"Of course all volcanoes will explode, as this is going to be a very severe pole shift. What about the months and years preceding the pole shift? It is no secret that Mammoth Lake and the caldera of Yellowstone are warming up, and the populace has been prepared for these occurrences by the movie Volcano where there, in the middle of LA, lava is bubbling up. In fact, there is a fault line running from the approximate San Diego/LA area, up into the Sierras, and this is liable to rupture rather violently during one of the quakes that precedes the pole shift by some months. Volcanic eruptions from that area in the Sierras can be expected. Will Mount St. Helen erupt? All volcanoes that have been active within the memory of man will begin spewing and burping and oozing, and many that were not expected to become active will reactive. "   ZetaTalk - Feb 15, 2000

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.

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.

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.

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.

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.

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."

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.

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.

glacial flood and small phreatic explosion (Icelandic Civil Protection)
http://www.volcanodiscovery.com/kverkfjoell/news.html
A small phreatic eruption seems to have taken place yesterday at the ice-covered Kverkfjoell central volcano. The steam-driven (no fresh magma involved) explosion followed a small glacial flood on 15 August the Kverkjökull glacier released into the Volga river and was probably a result of the pressure release during the flood.

Lascar, Chile, 5592 m August 14, 2013

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.

Veniaminof - ALASKA : activity rebounding August 13, 2013

the eruption has found a real momentum since yesterday.
On webcam Perryville could see yesterday, some nice ash emissions swept westward.

According to the bulletin of the AVO ashes stood on the image to about 3600 m altitude.
This activity comes back clear and net thermal signal, visible even now on captured by the GOES satellite images.

The same newsletter AVO indicates that thermal signal can be explained by the presence of active lava flows.

A plume of ash saw yesterday from Perryville.

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.

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.
