"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

activity update: likely lava lake in summit crater
http://www.volcanodiscovery.com/heard/news.html
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.

The activity of the building seems to know for a few days renewed.
the presence of the flows continues to manifest itself in a (small) thermal signal.

On the ground the eruption continues to fuel flows and, according to the images of the webcam installed Kozyrevsk, even vigorous activity in the cone. The glow of the latter is in fact returned pretty intense these days. A photo taken on July 23, can see both the cone is actually active and the flows escaping nearby are always supplied, but progress in tunnels.

White Island: aviation alert to yellow

The Geonet decided to change this morning the alert level of aviation in the White Island from green to yellow, but without affecting the level of volcanic activity, he remains at 1. The tremor has indeed tended to increase during the night

On the site potent activity in pools of mud, with projections up to 30 m in height and intense gas jets. .A situation similar to what was observed a year ago.

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.

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.

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.

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.

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 eruptive activity continues at Popocatepetl. Since Saturday the building supplies abundant gas plume whose ash content is generally low. Sometimes the most explosive phases produce rich ash plumes"
"Side population in many respiratory and eye problems have been identified following a few
60 hours of continuous ash falls on the northwest side between Wednesday and Saturday. Obviously the people who occupy this side complain that they receive no help from the federal state. Worse, the evidence collected by journalists in several villages indicate that, despite the passage warning yellow-3 health centers remained closed despite the large numbers of people affected."
