"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

Long Dormant Chilean Volcanic Complex Reawakens (Dec 13)

A "unique" burst of activity at a little-known volcanic complex near the Chile-Argentina border has attracted the interest of international scientists and led worried governments to plan for a potentially devastating eruption.

The volcanic field at the Laguna del Maule, located in central Chile near the Argentine border, has risen around two meters (6.5 feet) since 2007, undergoing "uplift" at a rate and consistency that is unprecedented in recent history, scientists said.

That likely means magma is exerting pressure on the Earth's crust in a zone where evidence indicates that explosive eruptions have happened repeatedly in the last few thousand years, though none in modern times.

If such an eruption were to happen at Maule today, it would have the potential to devastate nearby hydroelectric projects, and pump out ash that could wipe out crops across Argentina's pampas and severely disrupt global air traffic.

"We have so little experience with this kind of data, but the uplift is the biggest seen anywhere on the planet," said Bradley Singer, a geoscientist from the U.S. University of Wisconsin-Madison, who is leading an international research effort to understand what is happening under the surface.

"No-one has a seen a signal this large and this persistent. And it's in an area with an explosive record."

Scientists emphasize that it is impossible to know if or when Maule will blow again and how large any eruption would be.

Argentina and Chile have been working increasingly closely on monitoring the Andes volcanic chain that runs down their shared border. Most of the volcanoes - some 15 percent of the world's total - are located on the Chilean side, but winds usually mean Argentina faces the brunt of any ash cloud.

High in the remote Andes, the Laguna del Maule complex is centered around a deceptively calm, intensely blue lake of the same name, surrounded by arid volcanic rock.

The nearest towns are San Clemente in Chile, around 122 kilometers (76 miles) away, and the slightly closer Malargue on the Argentine side. Chile's capital Santiago is some 300 kilometers to the north.

About 2,400 people live or work in the nearby area, and the Maule river valley supplies around 25 percent of Chile's energy via 14 hydroelectric stations.

One of the people who knows the zone best is Raul Torres, an official who has lived close to the lake for around 60 years.

"About 10 or 15 years ago I noticed a real change in the area," he said, noting that the icy water temperature has warmed, algae have bloomed, and bubbles have appeared on the lake surface."

Mount St. Helens shakes 120 times within a week as volcano recharges, scientists say

http://www.seattletimes.com/seattle-news/northwest/mount-st-helens-...

In less than a week, four swarms of more than 120 earthquakes shook Mount St. Helens in late November. Although they were too small to be felt even by someone standing directly over their epicenters, scientists say they reveal the volcano is likely recharging.

“Each of these little earthquakes is a clue and a reminder we are marching toward an eruption someday,” said Weston Thelen, a U.S. Geological Survey seismologist with the Cascades Volcano Observatory in Vancouver.

However, “there’s nothing in this little modest seismicity, and none since 2008, that is a really good indicator of when that eruption will be.”

The earthquakes occurred between 1 and 2 miles below the surface and most registered at magnitudes of 0.3 or less; the largest was a magnitude 0.5. While the quakes are too small for human perception, scientists are able to study them thanks to sensitive seismometers stationed around the mountain.

As magma comes into the volcano’s system and is stored, scientists think that it releases gases and fluids that travel up into cracks, pressurizing and lubricating them, and causing small quakes.

“We know Mount St. Helens is slowly repressurizing. We can’t see it, but we think it’s inflating subtly,” said Liz Westby, a Cascades Volcano Observatory geologist.

Indeed, USGS scientists haven’t detected any anomalous gases or increases in ground inflation since the earthquake swarm.

“St. Helens is a well-behaved volcano, as far as we can tell,” Thelen said.

Westby said researchers have seen these kinds of earthquake swarms before.

Similar seismic episodes occurred during recharge periods between 1986 and the 2004 eruption; the small earthquake clusters resumed shortly after the eruption ended in 2008 and have continued periodically. Most recently, swarm earthquakes were detected in March through May of this year.

Scientists don’t exactly know how the volcano’s plumbing is laid out, but the little earthquake clusters give them a slightly clearer picture of what’s happening beneath the surface. By measuring how the speed of the seismic waves change as they move through the earth, researchers can better understand rock densities and where magma chambers are.

“These quakes don’t happen very often; you have to really exploit the ones we do get,” Westby said. “(It) gives us a better understanding of what’s going on and tells us where we need to do more research.”

Increasing Explosive Activity at Mexico's Colima Volcano (Dec 10)

Explosions are more frequent and increasing in size at the volcano in recent days.

Vulcanian explosions at rates of 1-3 per hour are producing 3,000 meter ash plumes that eject incandescent bombs onto the upper flanks of the volcano.

The active lava flow continues to creep down the southern flank along with incandescent rockfalls, alimented by the growing lava dome in the summit crater,

The arrival of gas-rich magma seems to manifest itself in this new phase of increased explosive activity, which likely will destroy the current dome.

Increasing Explosions at Peru's Sabancaya Volcano (Nov 28)

Sabancaya volcano in southern Peru continues to produce frequent explosions and now emits a continuous dense steam plume. Over the past weeks, activity has been gradually increasing.

Explosions are more frequent and stronger with plumes now regularly reaching more than 4000 m (2.5 miles) in height.

Peru's Geophysical Institute IGP reported 279 explosions during 14-21 Nov, a slow increase in SO2 emissions (up to 7000 tons/day) and some deformation of the volcano's SE flank, likely a result of a rising body of magma.

Strong Explosion at Mexico's Popocatepetl Volcano (Nov 25)

An unusually long and strong explosion occurred on 25 Nov 2016 starting from 10:47 local time.

A continuous jet of steam, gas, and fragmented volcanic material which lasted about 20 minutes rising 3 miles.

The dramatic eruption spewed ash over the nearby city of Atlixco Puebla.

During the previous 24 hours, there were 324 volcanic eruptions.

Several moderate to strong explosions have been reported on November 20, 2016 at Fuego volcano in Guatemala

Loud rumbling noises! The resulting column of ash and gas reached 5 km above the volcanic peak, is dispersing towards S and SO over an area of more than 15km.

Ashfall was reported in Morelia, Santa Sofia and Panimaché. No evacuations are underway.

The rumbling noises produced by each loud explosions were heard several kilometers away.

Pyroclastic flows have also been observed descending along the side of the volcano in the Ceniza and Trinidad canyons.

It’s not just the Fuego volcano that shows an enhanced volcanic activity, it’s all around the world since the deadly New

Zealand earthquake!

The volcano Zhupanovsky recorded two powerful explosions within 20 minutes on November 20, 2016.

The first eruption occurred at 14:29 local time, sending the ash and gas plume to an amazing height of 8 kilometers above sea level. The second ejection, 20 minutes later, sent ash up to 6.5 kilometers asl.

The Zhupanovsky Volcano in Kamchatka recorded to strong explosions on November 20, 2016, ejecting a column of ash to a height of 8 kilometers and 6.5 kilometers, respectively.

The first ash plume spread in a northeasterly direction, while the second was blown away in an easterly direction. Ashfall has been reported in settlements around the volcano.

Officials changed the level of Code Aviation danger to orange (high) and recommends tourist organizations not to conduct tours around the volcano.

Last time the volcano erupted was March 25th. Then the height of the ash column was eight kilometers. According to the Institute of Volcanology and Seismology (KVERT), all known volcanic eruption at Zhupanovsky were relatively weak and did not pose a threat for the surrounding populations.

The Zhupanovsky Volcano is a volcanic massif, consisting of four overlapping stratovolcanoes, located in the southeastern part of Kamchatka Peninsula, Russia. After 54 years of inactivity, the volcano began erupting on October 23, 2013, in 2014, and continuing nonstop into 2016.

Poasted Nov 11, 2016 - Two volcanoes, Sabancaya and Ubinas, erupt simultaneously in Peru – A first time for the country

http://strangesounds.org/2016/11/two-volcanoes-erupt-simulteneously...

Sabancaya and Ubinas volcanoes are separated by a distance of 100 kilometers, have different magma chambers, but they are erupting simultaneously right now! What a rare coincidence!

Both volcanoes are sending large volcanic cloud of ash and gas and show an enhanced seismic activity. Impressive explosions occur about every 4 hours, but every 15 minutes a small explosion occurs.

Sabancaya Ubinas and are separated by a distance of 100 kilometers. According to volcanologists, they have different magma chambers and currently simultaneous eruptions. A rare coincidence!

sabancaya began erupting 4 days ago (Nov 6) for the first time in 18 years. Ubinas is active since 2013 and has constant explosive phases.

As explained by Orlando Macedo, the director of the Geophysical Institute of Arequipa: “We are witnessing the simultaneous activity of two volcanoes right now! A first time for Peru. According to our data, this will continue.”
