Ecuador Volcano increased its activity

April 28, 2013 - 5:54 pm

The increase in activity this weekend Tungurahua volcano, located in central Andean Ecuador, caused ashfall in seven nearby villages, reported Sunday the Geophysical Institute of the Polytechnic.

According to the Institute, from 05.30 local time (10.30 GMT) there was an activity that generated pulse emission column rose up to four kilometers above the crater containing the ashes.

There she blows: Mount Etna erupts for 13th time this year spewing ... [Mail Online; 29 April 2013]

There she blows: Mount Etna erupts for 13th time this year spewing lava and ash hundreds of feet into the air

• Experts said violent eruption was 'spectacular' but not a risk to residents 

• The huge burst on Saturday could be seen for miles by surrounding towns 

• Town mayors called on the Government to introduce state of emergency

Mount Etna burst into life once more at the weekend as it shot lava, ash and smoke hundreds of feet into the air. 

Residents had been warned about the imminent eruption as grey smoke has been seen rising from the volcano for days. 

On Saturday, red hot lava was spat into the air as the volcano violently erupted once more.

Smoke and ash were sent up to 3,000ft in the air as Mount Etna erupted for the thirteenth time.

Experts said the eruption was 'very spectacular' but said local towns and residents were not at risk.

It is the thirteenth time Etna has erupted this year. 

Such is the scale of the activity that concerned residents have called on the Government to introduce a state of emergency.

However, experts said the latest activity posed no risk to local residents or towns. 

Stefano Gresta, president of the National Institute of Geophysics and Volcanology, said it was 'very spectacular, but not risky', according to youreporternews.it.

The airport was only briefly closed and the eruption caused very little disruption. 

The huge burst on Saturday could be seen by miles around and witnessed by residents of Catania and Taormina. 

Ash was sent flying down Etna's slopes and smoke rose more than 3,000ft into the air. 

Locals said the latest eruption is the most 'intense' of the year so far.

Ash was sent down the slopes of erupting Etna, which dwarfs towns that sit at the foot of the volcano

Huge plumes of smoke had been seen rising from the volcano for days before the eruption

The eruptions ended shortly before midnight on Saturday, although further bursts of activity were recorded yesterday. 

A series of minor earthquakes, measuring up to 2.55 on the Richter scale were also recorded. 

Earlier this month, mayors of towns surrounding the volcano called for 'urgent' government action. 

In a joint statement, the politicians said they wanted a state of emergency to be declared. 

Mount Etna is Europe's tallest active volcano. 

After past explosions, authorities in Sicily have been forced to build dams or dig ditches to divert lava away from people's homes. 

In 2008, an eruption continued for 417 days and was accompanied by more than 200 earthquakes.

Minor explosion reported at Alaska's Cleveland Volcano (May 5)

Scientists say there were two or three minor explosions at Alaska's Cleveland Volcano on Saturday morning.

The Alaska Volcano Observatory and U.S. Geological Survey say satellites detected a small, low-altitude ash cloud and elevated surface temperatures at the summit. The Federal Aviation Administration said there are no flight restrictions as a result.

Ecuador: Tungurahua Volcano generated seven explosions
The Tungurahua volcano, located in the central Andes of Ecuador and nine days ago saw the start of a new eruptive pulse maintains a moderate seismic activity, although the trend "slightly increased", informed the Geophysical Institute (GI) of National Polytechnic School.
Seven explosions, half hundred minor earthquakes related to fluid movement inside, and ten periods of constant shaking (tremor), by emissions of gas and ash, were recorded in the colossus in the last 24 hours, said IG report.
"The explosions are moderate, but some of them generate strong guns"
The strength of one of the "guns" produced windows shake and soil in nearby such as Pondoa and Runtín and was also heard in the tourist town of Baños de Agua Santa, at the foot of the volcano.

Kilauea (Hawaii / USA):/ Increasing activity

Looking at the electronic tilt on the northwest rim of Kilauea’s caldera, we notice that the summit has been steadily inflating since May 5th. In its latest update (May 10th), HVO indicates that “conditions of unrest have increased slightly: At the summit, there was general inflation with a rising lava lake, clusters of earthquakes south of Halema`uma`u that spread out across the south flank, and an increase in microseismicity in the Upper East Rift zone.

The tiltmeter on the north flank of Pu`u `O`o generally records weak inflation. GPS receivers on the north and south flanks of the cone have been recording extension since late-April along with increasing seismic tremor levels.

The situation should be closely controlled. There seems to be a strong lava ascent and the lava flows issued from Pu’uO’o are qu

Scientists: 2nd Alaska volcano is heating up, with seismic action signaling possible eruption  (May 13)

Another volcano in Alaska is heating up, with seismic instruments signaling a possible eruption, scientists said Monday.

Tremors were detected at Pavlof Volcano, 625 miles southwest of Anchorage, according to the Alaska Volcano Observatory. Satellite imagery showed the mountain was “very, very hot,” said John Power, the U.S. Geological Survey scientist in charge at the observatory.

The aviation alert level for Pavlof was raised from “yellow” to “orange.” A major ash emission could threaten international flights.

Pavlof is 37 miles from the community of Cold Bay, which was notified of the new activity that began about 8 a.m. Monday. Because of clouds, the volcano was not visible to the village of 100.

The volcano last erupted in 2007, but residents there said that eruption had no impact on Cold Bay, likely because the winds blew any ash fall away. Ash clouds were visible to residents, however.

Pavolf Volcano on Alaska's Aleutian Islands Eruption "Could Last for Months" (May 16)

The Alaska Volcano Observatory said Thursday a continuous cloud of ash, steam and gas from Pavlof Volcano has been seen 20,000 feet above sea level.

The lava fountain is estimated to haven risen several hundred feet into the air.

Onsite seismic instruments are picking up constant tremors from the eruption at Pavlof, located about 625 miles southwest of Anchorage.

Residents of Cold Bay, 37 miles away, have reported seeing a glow from the summit.

“As it got darker you could really see it shooting up and out — and then you could see the lava flow going down the side of the mountain.”

Pavlof was also shooting up ash clouds — some of them rising up to 20,000 feet.  

Jeff Freymueller, coordinating scientist at the observatory, said there's no way of predicting how long the eruptions will last. “It certainly could last months,” he said. “At this point we’re assuming that it’s going to be at least weeks.”

On Friday, the peak’s activity persisted, with small traces of ash now detectable in the atmosphere and nearly continuous tremors measured by five remote stations. Four of the stations are located about 6 miles southeast of Pavlof; the remaining station is 19 miles south but it's also detecting activity.  

Freymueller described the tremors as a continuous vibration, making it difficult to gauge the severity of the tremors.

But the activity is more severe than the 2007 eruption, a burping episode of subdued shakes and minor ash clouds, according to AVO. The tremors are 30-60 percent larger than the previous eruption’s. That may mean more magma spouting from the crater.

Turrialba Volcano spits massive ash and gas trail  (May 21)

At 5 a.m. Tuesday morning, the Turrialba Volcano, located east of the province of Cartago, began to spew gas and ash from two crater openings, the Volcanological and Seismological Observatory of Costa Rica (Ovsicori) reported.

By 8:30 a.m. a significant amount of volcanic material was released from the two openings of volcano, "which may indicate that these materials come from deep areas,” Ovsicori said.

"It is uncertain what will happen. Volcanologists are heading to the site to evaluate the activity," the statement said.

Experts said Tuesday's activity is “normal for an active volcano such as Turrialba,” but they recommended all nearby communities remain vigilant in coming hours.

The released material fell into grasslands and communities in the canton of Turrialba and reached some three kilometers west of the crater.

The trail of gases and ash can be seen from various locations in the provinces of Cartago, San José, Heredia and Limón. Public access to the volcano area was closed last year due to the activity.

Copahue: the situation could change- CHILE- ARGENTINA

The SERNAGEOMIN yesterday issued a complete report in which volcanologists describe an evolving situation in Copahue.
Even on the surface phenomena subside with such a no ash plume, seismicity only grow.

The image taken a few minutes ago: hard to believe that the whole edifice vibrates under the influence of a magma ascent. Image: SERNAGEOMIN

Chilean volcanologists Register now indeed indicate an average of 356 tremors an hour, sometimes so close in time they simulate a tremor (which is a continuous vibration). However, they state that no tremor was recorded at the moment.
They think that the events of recent days are to be linked with the development of a pocket of magma and therefore can not rule out a change in the situation until a phreato-eruptive magmatic activity or purely magmatic. It could be, according to them, similar to that experienced in the building in December 2012.

Red alert and ordered evacuated Copahue volcano area- CHILE -ARGENTINA

http://laculturevolcan.blogspot.fr/2013/05/copuahue-le-niveau-daler...

IThe last report SERNAGEOMIN explains the transition to the maximum warning by the pursuit of an abnormally high seismicity, albeit lower level, and the extent of deformation on the northeast side of the building (17 cm cumulative several months). These measures clearly indicate the development of a pocket of magma at shallow depth beneath the building. An explosion has been heard yesterday just after 22:30 (local time) Argentine side and it seems that, for the moment, whether it is the only eruptive event that occurred.

http://www.emol.com/noticias/nacional/2013/05/27/600729/decretan-al...

The resumption of activity of the massif has produced a string of earthquakes during the last hours, so Onemi declared red alert.

SANTIAGO. - The National Emergency Office (Onemi) Monday declared a red alert for the Alto Biobío, due to the reactivation of the volcano Copahue.

It has been decreed the alert, because the volcano's activity has increased in frequency and seismic activity, which, in the opinion of SERNAGEOMIN-is in the process of eruption risk, "said the minister at the end of a video conference held with the committee emergency in the Eighth Region
In that line, "instructed the immediate evacuation of people living within a radius of 25 kilometers around the volcano Copahue", ie 2,240 people (460 families), who will be referred to shelters arranged in the towns of Ralco, Guallalí and Chenqueco.

Priority will be given to one of the valleys that are at the highest risk, tomorrow we will continue with the second, and within 48 hours we will have completed the process, "he added, remembering the bad weather front also affects the area.
The massif was monitored from Friday after it was recorded "minor eruptive process dominated hydrothermal system." In fact, in the last 24 hours had recorded an average of 455 low-magnitude earthquakes per hour.

SERNAGEOMIN officials conducted an overflight of the area, showing an intense fumarolic activity concentrated in three sectors, two of which predominated steam and sulfur gases, while the third had a gray color because ash particles.

Meanwhile, Argentine authorities of the town of Caviahue, in northern Neuquén, decreed yellow alert and decided to suspend classes as a preventive.

Kamchatkan volcano Shiveluch emits 9-kilometer-tall plume (jun 9)

http://www.earthweek.com/2013/ew130614/ew130614d.html

The Kamchatkan volcano Shiveluch has thrice emitted columns of hot volcanic ash and gas. The tallest plume reached nine kilometers above the sea level, the Kamchatkan branch of the Russian Academy of Sciences' Geophysical Service reported on Sunday.
A code orange alert was issued for the volcano.

"Volcano seismicity is excessive, with rocks tumbling down its slopes," the report said.

In turn, the Kamchatkan territorial department of the Russian Emergency Situations Ministry said Shiveluch did not jeopardize residential areas and there had been no ash-fall.

Rescuers do not recommend visiting the erupting volcano, because ash may cause allergy in people and clog automobile systems.

Shiveluch is the northernmost active volcano of Kamchatka; it is situated 45 kilometers away from the Klyuchi town in the Ust-Kamchatsk district with the population of about 5,000. It is also one of the largest volcanoes in Kamchatka. Activity of Shiveluch intensified in May 2009, and a crack of about 30 meters deep went through its dome.

Huge Popocatepetl Volcano Eruption - Jun 17

Mexico’s Popocatepetl volcano registered a massive explosion spewing ash and incandescent rock almost 4 kilometers high. Authorities have warned that winds could blow the ash cloud as far away as Mexico City.

Inhabitants of villages up to 25 kilometers from Popocatepetl (colloquially known as ‘Don Popo’) rushed out of their houses when the massive explosion reverberated through their homes.

Esther Matinez, resident of Amecameca municipality, told Mexican publication La Jornada that the blast was like a rocket explosion. Around 4.5 million people live within a 50-kilometer radius of the active volcano, 650,000 of whom are considered to be at high risk.

According to authorities in the state of Puebla, where the second-tallest volcano in Mexico is located, the incandescent fragments released in the blast fell as far as 2 kilometers from the crater. Director of Puebla’s Civil Protection department Jesus Morales said that burning rocks sparked small fires around the volcano.

“There were clouds at the time of the eruption so it was possible to observe the large shock wave accompanied by a plume of ash and incandescent material,” Morales said.

Mexico's National Center for Prevention of Disasters (Cenapred) said the volcano had returned to its previous activity level, and that the volcanic alert level would remain at ‘yellow phase two.’ In addition, volcanic ash that was blown up to 4 kilometers into the air could be shifted by wind currents and then fall on Puebla, or even as far away as Mexico City, Cenapred warned.

Judging from a short video that can be seen on Facebook, it seems a second lava pond has appeared in the crater of Bembow, to the north of the former one. Actually, on Bembow and Marum, these are more lava ‘cauldrons’ than lava ‘lakes’ like the ones to be seen on Kilauea or Erta Ale. Here, it’s a permanent and vigorous bubbling of lava.

Alaska's Pavlof Volcano Eruption Intensifying (June 25)

Pavlof volcano has spewed ash and lava for the past six weeks but erupted with new intensity early on Tuesday, belching a plume of cinders 5 miles into sky and onto a nearby town and disrupting local flights, officials said.

The eruptions from Pavlof were its most powerful since its current eruptive phase began with low-level rumblings in mid-May, according to scientists at the federal-state Alaska Volcano Observatory.

The latest series of more powerful ash-producing blasts from the crater of the 8,261-foot (2,518-meter) volcano started late on Monday and continued overnight into Tuesday, scientists said.

"For some reason we can't explain, it picked up in intensity and vigor," said Tina Neal, an observatory geologist.

While the ash plume has so far remained too low in the sky to affect jetliner traffic, topping out at an altitude of 28,000 feet, smaller planes had to fly around it, officials said. Anchorage-based PenAir canceled one flight and re-routed others, said Missy Roberts, a company vice president.

Ash has dusted King Cove, a town of about 900 people located 30 miles southwest of Pavlof, the Alaska Volcano Observatory reported.

The National Weather Service issued an ash advisory for the region, warning of breathing problems for people with respiratory ailments and potential damage to exposed electronic equipment.

A second Alaska Peninsula volcano continued a low-intensity eruption, the observatory said. Ash from Veniaminof Volcano, 485 miles southwest of Anchorage, has been limited to the area around its 8,225-foot (2,507-meter) summit, the observatory said.

A third, more remote, Alaska volcano remained restless but was not currently spouting lava or ash, the observatory said. Cleveland Volcano, 940 miles southwest of Anchorage, began an on-and-off eruptive phase in mid-2011 but has not produced an explosive eruption since May 6, according to the observatory.

Popocatepetl Erupts 39 Times In 24-Hours (July 10)

Video of crater view from the air

Mexico's Popocatépetl volcano is keeping up its recent activity, emitting 39 exhalations over the past 24 hours. Ash, gases and steam expelled out of the volcano's crater this morning reached well over a mile in the air. The lava dome on "El Popo" - the mound of viscous magma which, being extruded from the crater's vent, dries and piles up not far from it -- continued to swell. Overnight, glowing fragments expelled from the inside of the volcano could be seen on its slopes.

El Universal wrote that one of the most significant emission of ash, steam and gas occurred today at 7:00 this morning. The volcano also registered tremors of "high and low frequency" as well as medium-sized micro-tremors occurring as a result of the movement of magma over the course of several hours.

"El Popo," one of several nicknames by which the Popocatépetl volcano is known by nearby residents, is located in Puebla state, about 43 miles southeast of Mexico City. Ash from recent fits of activity in the past few weeks have reached as far as Milpa Alta, one of the southernmost boroughs of the capital.

Authorities raised the alert level on the volcano back to Phase 3 Yellow on July 7 after several weeks of lesser activity. Ash from the volcano had disrupted flights into Mexico City, with over 40 American flights cancelled last week as a consequence of the volcanic ash.

The alert level is one step below Red, which would make necessary an evacuation of the surrounding area. Already it recommends that people stay away of a 12-kilometer exclusion zone around the volcano, and suggests that residents in towns in the area wear masks and long-sleeved shirts to prevent inhaling ash expelled the volcano. Cenapred estimates that in the event of a severe eruption, evacuees would tally up to more than 11,000 people from a total of 18 municipalities residing in the shadow of the volcano.

Fifty thousand people live in 24 towns surrounding Popocatepetl, whose name means "smoking mountain" in the Nahuatl Indian language.

The last newsletter CENAPRED indicates that during a survey conducted yesterday, volcanologists have noted the presence in the summit crater of a new active dome, about 250 m wide.
The detail is important because the dome would be a more effective "plug".

Big explosion this morning at Popocatepetl

http://laculturevolcan.blogspot.fr/2013/07/grosse-explosion-au-popo...
Browsing data VAAC Washington, it may be noted that reference is made to an exhalation which occurred around 8:10 GMT or 3:10 hours Mexican.
These images are indeed to believe that it is not a mere exhalation, as suggested by the VAAC, but a strong and brief explosion.

Two images
The first, taken by the Webcam of Tlamacas shows a very important incandescent zone on the eastern slope of stratovolcano at the hour of the event. This glow zone persists over several successive images, unlike most of the benefits of blocks and bombs, the cooling caused the disappearance them glow very quickly.

Blocks fell on all sides, but the slope is most affected by the explosion. Image: CENAPRED

It persists so that to ask if a lava fell into place, before it fades thereafter.

The other image that can give a fair dimension to the event is provided by the webcam installed in San Nicolas de Los Ranchos (opposite side is precisely). It shows, in a very low cloud ceiling, blocks propelled by the explosion.

blocks rolled up more than 4 km away from the crater into the wooded area, which stops around 3900 m above sea level on the slope. Rare during this crisis were the times or blocks have reached this distance.

Some more or less powerful explosions may occur in the coming days. They are even quite logical in the situation of Popocatepetl.

This is a possible mechanism (hypothetically) to explain the explosive activity "untimely": the dome is in place, although initially composed of a relatively fluid lava began to stiffen as a result of its cooling. It is therefore a more effective cap until it was being built. And while there, after 10 days of intense activity, less gas in the column of magma that built the dome, it is more difficult for him to escape because of the "plug". The latter can therefore generate pressures that create these brief explosions and more or less intense.

In any case it is because the activity may still be some surprises that the alert level is currently maintained by the yellow-3 CENAPRED.

Spectacular images that come from Ecuador following the violent explosion of the volcano Tungurahua yesterday.

Eruption Intensifies at 2nd Ecuador Volcano (July 17)

Lava flow and ash and gas emissions have intensified at a second Ecuadorean volcano, Reventador, as the full-bore eruption of the Tungurahua cone continues.

Reventador is located on the eastern branch of the Andes, has shown a significant increase in seismic activity, and is accompanied by the emission of a lava flow descends the southwestern flank of the cone, a phenomenon that has been observed since July 13.

Although gas emissions and a high level of seismic activity that is associated with the eruption, not as a threat to small towns in the area, or for roads or oil industries who live in the region.

The 11,400-foot (3,475-meter) volcano is nearly three times that distance from Tungurahua to the southwest which has been roaring since Sunday, when 200 people were evacuated from its flanks and one pyroclastic blast was heard as far away as the coastal city of Guayaquil.

Explosive Eruption at Japan’s Sakurajima Volcano (July 21)
A strong vulcanian explosion occurred at 11:02 GMT.  A loud cannon-shot bang accompanied the explosion, which generated a large mushroom cloud that reached 12,000 ft (3.7 km) altitude and engulfed the NE half of the Sakurajima peninsula and was followed by several smaller ones within about half an hour.

The volcano and much of the surrounding areas remained under the ash plume for several hours. In the hours after the explosion, the Showa crater continued to emit ash plumes in often near-continuous pulses, sometimes reaching several hundred meters in height, but with no visible incandescence or audible sounds.

2 Indonesian Volcanoes Erupt, Hundreds Flee, Officials Urge Calm (July 22) Indonesian officials urged people living near Mount Merapi to remain calm as the volcano belched thick black smoke and volcanic ash into the air, forcing hundreds to flee along its slopes.

The volcano unleashed a column of dark red volcanic material 1,000 meters into the air as terrified residents fled to safety.

The sound was heard 30 kilometers away.

"This was not an eruption, just the sliding-down of volcanic material from the top of the volcano," said Agus Hendratno, a geologist and lecturer at Gadjah Mada University in Yogyakarta. He said this is a common process in which part of the volcano's lava dome collapses, releasing ash and volcanic material.

Meanwhile, another volcano, the 1,500-meter Mount Lokon in North Sulawesi also erupted at 5:06 a.m. spewing a column of ash and smoke 2,000 meters up into the sky and spreading ash on the southern flank of the mountain.

Farid Sukendar, the head of the vulcanology observation post monitoring Mount Lokon, said that the eruption came as a surprise.

activity update: likely lava lake in summit crater

Recent satellite images suggest that a lava lake is most likely currently active in the summit crater of Mawson Peak.
NASA satellite infrared images show a very hot circular object of about 100-150 m in diameter that plausibly could only be produced by the strongly heat-radiating surface of a lava lake. Currently, no lava flows seem to be present on the other hand.

Russia’s Shiveluch Volcano Spews Ash 3 Miles High (Aug 5)

Russia's northernmost active volcano erupted Monday sending a cloud of ash 6 km into the atmosphere. 

This is the third release of ash by Shiveluch in recent days.

Two other eruptions occurred on July 29 and August 1 when the column of ash also reached a height of 6 km height above the sea level.

Shiveluch volcano has been increasingly active since May 2009.

Update on the ongoing eruption at Mt Rokatenda (Aug 11):

"The activity...remains high and at dangerous levels. There are no signs it will stop erupting any time soon," Surono, an official from the state vulcanology agency, said.

The volcano threw rocks and ash 2,000 metres into the sky and sent torrents of molten lava onto a beach, killing three adults and three children as they slept.

A rescue team is struggling to evacuate some 2,000 people inside a three-kilometre exclusion zone. A group of "traumatised" inhabitants have already left the island.

Team member Bakri Kari said rescue efforts were difficult as roads were blocked by ash and people were reluctant to leave their homes.

"It was tough trudging through hot ground covered in ash that was 10 to 20 centimetres thick," he said.

"Everything was burnt by the lava.

"People were scared and many were crying. They wanted to get away from the volcano but at the same time they were reluctant to leave their livestock and homes."

Rescuers have recovered the bodies of the adults killed on the beach but the children are yet to be found, he said.

About 2,000 people had already been evacuated to Flores before Saturday's eruption, leaving around 8,000 people still on the island.

Lascar is yellow alert . Not very large, the seismicity of the building is still a little "abnormal" with 245 tremors recorded. The majority of them (216) are related to the simple fracturing fluids without moving. The other 19 are shaking Long Period kind, caused by fluid movement in the building. Of these 19, 11 are jerks "tornillo" type, special seismic signals that have been described for the first time at Galeras in 1993, before an explosion killed several scientists symposium on site. It has since been shown that this type of signal is not necessarily a precursor of eruptive activity but encourage greater vigilance when it is saved.
From the outside, the building is fairly "zen" with a simple discrete degassing.

New phase of intense activity at Pacaya tonight- GUATEMALA

From 19:15 (local time), the eruptive activity of Pacaya began to show a clear upward trend, producing a tremor that has saturated the seismometers. Intense Strombolian activity began, with projections of bombs and blocks to a height of 500m, watering the slopes of Mac Kenney cone. VAAC Washington, alerted, issued a bulletin states that the ashes were not visible but a thermal anomaly has been identified at the beginning of the crisis, just before major cloud masses are block signal.

Quickly ash falls were reported near the building in the village of El Rodeo and El Patrocinio. Meanwhile a new casting began his training on the west side, rising up to a distance of about 500 m.

Sakurajima spews its highest volcanic column ever at 5000 meters [THE ASAHI SHIMBUN: 18 August 2013]

KAGOSHIMA--A spectacular eruption of Sakurajima volcano here sent up its highest plume in recorded history on Aug. 18, the Kagoshima Local Meteorological Observatory said.

The cascading column of smoke, caused by a massive 4:31 p.m. eruption, rose about 5,000 meters from the Showa Crater.

It marked the 500th eruption this year of the 1,117-meter-high mountain.

Blown by winds from the southeast, a large amount of volcanic ash fell in the central part of Kagoshima city, the capital of Kagoshima Prefecture.

The sky above the downtown area of the city became dark and visibility temporarily deteriorated.

Some passers-by shielded themselves from the ash with umbrellas. In addition, many drivers were forced to turn their car lights on in the darkened driving conditions.

White Island Volcano Vents Mile High Steam Off New Zealand (Aug 20)

White Island volcano erupted this morning, sending large plumes of steam into the sky.

Started about 10.20am, the volcano producing a steam column which rose about 2 km above the island.

"Whether it's going to develop into something over the next few hours or couple of days is too soon to tell," GNS vulcanologist Steve Sherburn said.

"There's always steam coming out of the island but there was a big shot of steam for about 10 minutes."

The plume was clearly visible from Whakatane, and as far as suburban Tauranga and Mt Maunganui this morning.

Western Bay of Plenty locals told Stuff they had immediately recognised the steam rising above the landscape as evidence of a White Island eruption.

White Island started to show signs of new activity last month, including jets of gas being shot through its small lake and sediments being ejected 30 metres into the air.

A retiree who'd lived along the coast all her life said it was by far the largest White Island plume she'd ever seen. "It's a constant threat along this coast. She could go at any time."

Indonesia Warns of Rising Volcanic Activity in East Province [The Wall Street Journal; 22 August 2013]

JAKARTA, Indonesia—Indonesian authorities have been warning local villagers in East Nusa Tenggara Province about increasing volcanic activities in the area in recent days.

Agence France-Presse/Getty Images

Mount Rokatenda volcano, shown here on Aug. 12, killed six people on Palue island two days earlier. Authorities are now watching two other volcanoes, subsea Mount Hobalt and and Mount Ili Werung, in the same eastern province.

“The people around the areas should continue to practice caution” despite there not having been fresh volcanic activity  on Wednesday,  said Sutopo Purwo Nugroho, the spokesman of the National Disaster Mitigation Agency.

The agency reported on Tuesday two volcanoes in the East Nusa Tenggara Province have shown “increasing activities.” The volcanoes are subsea Mount Hobalt and and Mount Ili Werung.

It noted Mount Hobalt erupted Tuesday morning, spewing cloud as high as 6,560 feet above the sea level for around two minutes.

“Visually, the water near the volcano turned yellow and bubbly,” the agency said.

Meanwhile,  Mount Ili Werung, located on the southern part of Lembata Island, started rumbling just before dusk Tuesday for about an hour and a half.

But the agency said, at least so far, it isn’t necessary for the villagers to evacuate their villages.

Six people were killed in the small Palue Island in the province when Mount Rokatenda erupted on Aug. 10, spewing hot ash and smoke up to 6,560 feet into the air. Nearly 3,000 people were evacuated from the area in the island since it first rumbled in October 2012.

East Nusa Tenggara is about  1,297 miles east of Indonesia’s capital city of Jakarta.  Just west to the province is West Nusa Tenggara Province, famous for the Mount Tambora, whose eruption in April 1815 is cited as the largest volcanic eruption in the world in recorded history.  The precise death toll from the eruption remains unclear, but it is believed to be at least 71,000. The eruption caused a “volcanic winter,” a reduction in temperature cause by volcanic ash and droplets of sulfuric acid. It made 1816 known as the year without summer due to the effects of the weather in North America and Europe.

New Submarine Volcanic Eruption in Indonesia (Aug 22)

An undersea volcano off of the southern coast of Lembata unexpectedly erupted over the last few days, producing strongly discolored waters and a plume that reached 2 km (6,500 feet).The latest GVP Weekly Volcanic Activity Report also mentions incandescence noted at the sea’s surface.

According to news reports, the volcano is called “Mt. Hobalt”, however, in the Global Volcanism Program‘s database, no such volcano exist. There is a Hobal that is part of the larger Iliwerung complex in the right area of Lembata, so this seems to be the volcano that is erupting.

This volcanic complex has been producing diffuse fumarolic activity since the beginning of the month and the PVMBG noted that seismicity has increased sharply in this area as well.  This new eruption from Hobal has prompted the PVBMG (Center for Vulcanology and Geological Disaster Mitigation) to put Hobalt on a Level II alert and warned fishermen and tourists to avoid the area.

There have been some fears that this activity near the coast could produce a tsunami, but so far those fears are unfounded. This would be the first eruption from Iliwerung since 1999 and much of the eruptive activity at Iliwerung has been from Hobal since 1973. The last known subaerial eruption from Iliwerung was in 1948 (but records can be incomplete across Indonesia).

Meanwhile, the continued eruptions at Rokatenda has caused a larger-scale evacuation of the region around the volcano. Seven hundred housing units are to be constructed for people who have had to leave their homes since October 2012 due to the ongoing activity. Recently at least 6 people died from a pyroclastic flow that swept across a beach where villagers were living on the island volcano.

Dome Collapse and Powerful Eruption at Santiaguito Volcano in Guatemala (Aug 22)

A major eruption occurred at Santiaguito Volcano on Thursday. The top part of the Caliente lava dome collapsed and produced a series of relatively large pyroclastic flows and explosions. Ash plumes rose more than 2 km to elevations of 4 km altitude.

The pyroclastic flows affected mainly the south, southeast and NNE sides. Bombs from explosive activity were ejected to distances of 500 m.

Volcanic 'Geyser' Erupts Close to Rome Airport (Aug 24)

Italian experts have been puzzled by the overnight appearance of a geyser crater spraying clouds of gas 15 feet in the air, yards from the end of the runway at one of Europe’s busiest airports.

Motorists on Saturday were alarmed to notice hot, stinking gas spurting from a newly formed crater in the middle of a roundabout close to the perimeter fence of Rome’s Fiumicino airport -- less than 900 yards from the end of a runway.

Spectators gathered around the smoking crater, which measured about six feet wide and three feet deep, before firefighters and vulcanologists arrived to seal off the roundabout to prevent inhalation of the gas, suspected to be a cocktail of carbon dioxide, hydrogen sulphide and methane. Tests are now underway.

While initial reports suggested the gas came from rotting organic matter trapped underground, one expert said volcanic activity was more likely.

“From Mount Etna in Sicily up to the Alban hills around Rome there is a good deal of underground volcanic activity,” Alberto Basili, a seismologist at the Italian National Institute for Geophysics and Vulcanology, told the Daily Telegraph.

The area covers Mount Vesuvius, which buried the Roman city of Pompeii when it erupted in 79AD, to a number of lakes formed in extinct volcanoes north of Rome.

Klyuchevskoi Volcano Erupts (Aug 27)
Powerful explosions were registered at the highest volcano on the Kamchatka Peninsula in Russia's Far East. The volcano spewed ash some 200-300 meters (650-985 feet) high in the air, while gas and vapor emissions occur within an interval of three to five minutes.

Apart from powerful mud flows that could form from ice thawing on the volcano's sides, the current eruption of Klyuchevskoi does not pose a threat to locals. Experts, however, say that the eruption could pose a threat to tourists visiting the volcano and local air traffic.

Last time the volcano erupted was in 2010, but its most powerful eruption in the recent years was registered between January and May of 2005. Following that eruption, the volcano "sank" by 50 meters (about 165 feet), from 4,800 meters (about 16,000 feet) to the current 4,750 meters (15,845 feet).

Alaska's Veniaminof Volcano Erupts in Step with 7.0 Quake (Aug 30)

The Alaska Volcano Observatory reported lava fountaining and ash emissions up to 20,000 feet (nearly 4 miles) from Veniaminof volcano Friday morning.

Scientists from the Alaska Volcano Observatory told that the latest emissions marked nearly the strongest unrest noticed this summer at the site.

Ash spewed from Veniaminof has already dusted the nearby village of Perryville, a fishing town with 112 residents, and light ash was expected to fall in other communities, according to the volcano observatory, jointly run by the state and federal governments and the University of Alaska, at Fairbanks.

Veniaminof, one of three Alaska volcanoes that have been restless this summer, began its latest eruptive episode in mid-June. But until now, ash clouds have been very small, mostly limited to the area around the peak's summit.

Seismic activity close to Mount St Helens- September 2, 2013

USGS geologists have been tracking an unusual sequence of earthquakes in recent weeks near Mount St. Helens. The swarm, which included M 3.7, M 3.4 and M 3.1 events on August 23rd, started on August 2nd with an M 3.1. They are occurring at about 20 km northwest of Mount St. Helens at a depth of about 16 km.

About 120 earthquakes in total have been recorded since the swarm began. People in Battle Ground, Clark County, reported feeling the M 3.7 event on August 23rd, but since then things have tapered off. The last measurable quake was a 0.6 magnitude on August 27th .

Similar activity has been recorded on the south side of Mount Hood, with 16 small earthquakes the largest of which reached M 2.0 on August 26th.

Of course, this is a signal that something is happening. But we still had to wait for suffisemment of bits of information in order to make a post.

The images of MTSAT-2 and MODIS finally today clearly show the presence of a plume that stretches up to a hundred kilometers away northeast.

Tokyo VAAC indicated in its latest reports that the ashes are walking at an altitude, all modest sum of 1600 m. With a building which rises to 799m, we can already conclude that the height reached by the plume is about 800 m. This estimate of the Tokyo VAAC is confirmed by the images produced by the Japan Meteorological Agency webcam installed on the volcano island close to Nakano-Jima.

Lava Flows Increasing at Fuego Volcano in Guatemala (Sep 2)

A phase of increased lava flow activity occurred this morning from about 6 am local time, generating a series of pyroclastic flows that descended several ravines on different, but mostly the southwestern side of the volcano.

The volcano has been in moderate effusive activity for at least the past two weeks, feeding relatively small lava flows on the upper steep slope. A sudden increase in effusion rate seems to have caused the destabilization of the lava flows, generating rockfalls that turned into pyroclastic flows.

The lava flows have quickly increased from previously 200 m to about 2 km length. The surge of magma supply is also suggested by the appearance of strong tremor pulses the previous night.

An ash plume rising as a by-product of the pyroclastic flows was reported to about 12,000 ft (3.6 km) altitude.

Ubinas Volcano in Peru Erupts 5 Times in 2 Days (Sept 3)

Ubinas Volcano in Moquegua registered two small eruptions on Sep 1.

A third eruption occurred the following day, and now the volcano has erupted twice more, bringing the total to five eruptions in less than 48 hours.

A number of news outlets have reported that the volcano’s sudden burst of activity has caused alarm in the area, which has been intensified by the appearance of a column of volcanic gases and ash that has reached a height of two kilometers.

The column of ash has deposited residue up to 10 kilometers away from Ubinas. However, Mariño Salazar stated that the ash column does not pose a danger to people or livestock at this time, as the wind is blowing it towards a mostly uninhabited area. Still, Salazar may meet with local authorities on Sept. 4 in order to discuss any necessary actions.

Scientists are investigating the cause of the eruptions.
