"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
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.

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

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.
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.”

PERU: PERU'S SABANCAYA VOLCANO HAS FIRST MAJOR ERUPTION IN A DECADE NOVEMBER 06
Sabancaya volcano had its first major eruption in more than a decade on Sunday, November 6. The volcano, which is located in Peru?s southern Arequipa region, continued to emit clouds of ash and steam on Monday.

BULUSAN, Sorsogon—Thrice during the past week, Mount Bulusan in Sorsogon belched out gray ash plumes in a series of minor phreatic (steam-driven) eruptions that sent ash raining over villages in the towns of Bulusan, Casiguran and Irosin, threatening crops and endangering the health of some residents.
Antonio Banares, 64, a resident of Barangay Central in Bulusan town near the slope of the volcano said he thought the ash falling from the sky last week was just drizzle.
“I became aware that it was ash and that the volcano had a (minor phreatic) eruption. I saw the ash thicken and I thought, this is bad, especially for my heart condition,” he said.
Banares and other residents in 11 barangays in Bulusan had been suffering from the effects of phreatic eruptions on Oct. 17, 19 and 21. The Municipal Disaster Risk Reduction and Management Council (MDRRMC) of Bulusan said the villages of Dancalan,
Madlawon, Poctol, Sapngan, Dapdap, Looban, Central, Sabang, Mabuhay, San Rafael and San Bernardo bore the brunt of
the ashfall which dumped up to half a millimeter thick of ash.
Fumes coming from the volcano drifted to the villages of San Jose and San Francisco.
The Philippine Institute of Volcanology and Seismology (Phivolcs) also found small traces of ashfall in the upland barangays
of San Rafael and Sabang in Irosin town during the Oct. 19 eruptions
In Casiguran town, Luisito Mendoza, the town’s MDRRMC officer, said at least 350 houses were covered by ash in
Barangay Inlagadian from the Oct. 21 eruption.
At least 10 residents were treated for vomiting and stomach ache, said Mendoza. Masks were also distributed to residents. He said “if the situation gets worse,” officials would order preemptive evacuation.
Nerma Ricero, principal of Inlagadian Elementary School, canceled classes Friday after 310 students reported difficulty in
concentrating on their lessons. Bulusan Mayor Mike Guysayko also ordered classes suspended in eight elementary and
secondary schools.
Farmer Salvador Hajas, 33, said the continued eruption of Bulusan volcano is destroying crops. “Our produce are affected.
They get rotten due to ash,” he said.
Renard Fullon Garados, MDRMMC officer in Bulusan town, said officials are conducting an inventory of households that
