"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

Sakurajima: sustained activity today
Sakurajima, Japan volcano is constantly erupting. Its activity is characterized by violent explosions, short, called "Vulcanian" (Vulcano, the wind turbine, which was described this type of activity Island). These are more or less frequent and violent depending on the activity level of the building.
At the moment it seems that the latter is relatively high. In any case that suggests this video taken today.

Particular note of the images on the left, the establishment of a fairly large pyroclastic flow

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.

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.

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.

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.

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.

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.

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

Kilauea, United State, 1222m

The eruptive activity exclusively effusive, remains at Kilauea. At the summit pit crater in the Halema'uma'u caldera, the lava lake is still present. Its relatively low level and stable since the end of April, began a slow rise since May 03, which has accelerated since 06.

The level of the lava lake on April 27

The level of the lava lake on May 9

On the East Rift Zone, the activity is always present. In the Pu'u O'o few brief outbursts occurred on hornito located on the eastern part of the floor, especially before yesterday. In addition, since May 07, a new casting progresses outside the Pu'u O'o, on the flank. It is clearly visible on the thermal camera located on this side.

The flows that feed lava Peace Day are still present. The lava progresses through a system of tunnels, from the area of ​​Pu'u O'o to the ocean. Lava enters the Pacific in two places, located either side of the northern boundary of the national park.

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.
