"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

Indonesia: Volcanic Ash Falls on Mt. Semeru

Indonesia, 7 Feb. (AKI/Jakarta Post) - Volcanic ash reportedly started showering some areas on the slopes of Mt. Semeru in Lumajang, East Java, on Tuesday morning.

Lumajang Disaster Mitigation Management head Rochani said the volcanic activity was still at a mild intensity level.

“Residents living in Besuk Sat, Pasrujambe district and its surrounding areas experienced the volcanic ash shower from Mt. Semeru,” Rochani said as quoted by tempo.co on Tuesday.

According to Rochani, the active volcano spewed gusts of hot cloud reaching 300 meters high from midnight to 6 a.m.

The Volcanology and Geological Disaster Mitigation Center (PVMBG) raised the alert status of Mt. Semeru as of Thursday last week, prohibiting local residents from going within a 4 kilometer radius of the volcano.

People are also not allowed to climb or approach the crater.

Volcano Activity in Cameroon on Monday, 06 February, 2012 at 19:10 (07:10 PM) UTC.

Cameroon state radio says that Mount Cameroon, a volcano in the country’s southwest region, sent ashes and flames into the air in a brief explosion. Cameroon Radio Television reported Monday that a violent explosion Friday lasted a couple of seconds and lightly injured two among the porters and guides on the mountain. Mountain guide Peter Buma Linonge told state radio there were explosions, then flames burst into the air followed by ash. Joseph Mokake, a resident of Buea, the town situated at the foot of the mountain, told The Associated Press there were tremors on Tuesday and Wednesday. He said he moved to a nearby town for safety. Residents say explosions and tremors serve as a precursor to a possible eruption. Measuring just over 13,420 feet (4,090 meters) high, Mount Cameroon is an active volcano and the highest peak in West Africa.

Santa Maria- Santiaguito Volcanoes, Guatemala, Geophysical Expedition Dec 2011- Jan 2012, preliminary report:

"

We collected >10 hours of synchronized images from the 5 cameras.  Some of the images have been stitched into a movie shown elsewhere on the blog.  We are still making sense of the image sequences, but here are some rough observations:

1) Parts of the dome are moving at >3.5 m/h.

2) Local inflation/deflation of the dome can occur as fast as 2.5 m in 13 minutes.

3) There are very hot regions of the dome that show no motion and persist over the duration of observations.

Time-lapse photography with particle image velocimetry and seismo-acoustic tilt signals for the night of January 7. Note clearly visible inflation and deflation of the dome, the active lava flow to the south (left side of animation), and visible explosions around 21:50, 22:15, and 24:31.

Ecuador Volcano Tungurahua Erupts:

Feb 04 2012 From approximately the 04:40 (local time) the morning of today began recording a constant seismic tremor signal. At 05:50 (local time) there was a burst of moderate size, which generated a roar about 5 minutes long, heard so mild Palitahua and Guadeloupe (14 km northwest of the volcano). There have been reports of mild roar and fall gravel (lapilli fine) grain size of coarse sugar rice Banos, Pillate and Juive. At the time from these areas is reported ashfall black.

MEXICO, POPOCATEPETL VOLCANO

Mexico volcano spews gas into skies near capital

Mexico's Popocatepetl volcano has been spewing gas, water vapor and incandescent materials into the skies near the country's capital for days, registering at least 14 "exhalations" late on Wednesday and in the early hours of Thursday, according to local media. The most significant emissions came on Tuesday afternoon and were accompanied by a small quantity of ash, scientists said, according to Excelsior newspaper reported . Local civil protection officials have been giving evacuation training in communities near Popocatepetl ahead of a possible eruption.

Lava Dome Forms on Mt. Cleveland, Alert Raised 

ANCHORAGE, Alaska — The warning level for a remote Alaska volcano has been raised after a new lava dome began forming, indicating the mountain could explode and send up an ash cloud that could threaten aircraft.

The Alaska Volcano Observatory on Tuesday elevated the alert status for Cleveland Volcano.

Officials say the new lava dome was spotted in the summit crater. The observatory says as of Monday, the dome was about 130 feet in diameter.

There have been no eruptions since Dec. 25 and Dec. 29, which destroyed the earlier lava dome built up over the fall.

Cleveland is a 5,675-foot peak on an uninhabited island 940 miles southwest of Anchorage.

Authorities say sudden eruptions could occur at any time, and ash clouds 20,000 feet above sea level are possible.

Here's a couple updates from last week...

Fuego Volcano (Guatemala)

Activity Update: Continuing Moderate Ash Explosions

Thursday Jan 19, 2012

Fuego volcano produced explosions observed on 11-13 and on 16 January, which produced ash plumes rising 400-1000 m above the crater. Shock waves and rumbling sounds accompanied the explosions and rattled windows and roofs in nearby villages.
Rock avalanches traveled SW into the Ceniza drainage and on the W, S, and SW flanks. At night on 13 and 16 January incandescence was visible from the crater.

Santiaguito Volcano (Guatemala)

Activity Update: Sporadic Explosions, Continuing Lava Dome Growth, Small Lava Flow on SE Flank

Thursday Jan 19, 2012

The lava dome growth of Santiaguito continues at moderate levels. Sporadic explosions produce ash clouds that rise up to 600-800 m above the lava dome and mostly drift SW. A viscous lava flow is active on the SE flank. Block avalanches are generated from the front of the lava flow and on the SW flank, accompanied by rumbling noises.

Nyamuragira Volcano (DR Congo)

UPDATE: Eruption Continues with Active Lava Lake and Lava Flow From New NE Vent

Friday Jan 27, 2012

During our recent expedition, we visited Nyamuragira's ongoing eruption during 22-25 January, and found that the eruption is still going on strongly, but somewhat less intense than during the first 1-2 weeks in January.
The second vent complex, which had started to form at the NE end of the eruptive fissure in late Dec or early Jan with about one week of constant fountaining, consists of probably 3 coalescent cones.
The middle and largest of them contained a crater filled with boiling lava, i.e. a small lava lake, which was strongly spattering every few seconds. The lava lake itself was not visible, but could be inferred from the strong glow and the hissing degassing noise of exploding gas bubbles that ejected liquid spatter bombs in all directions.
Some of the ejections reached up to about 200 m height and individual bombs reached the base of the cone....

New Strombolian Activity at Etna's New SE Crater

Saturday Jan 28, 2012

 

Sporadic strombolian eruptions have started at the New SE crater on 27 Jan, following ash emissions observed the previous day.
Explosions were observed at 19:54, 20:05, 20:54, 21:11 and 22:40 local time according to Etna Walk who monitor the webcam of INGV. The explosions ejected bombs up to a few tens of meters above the crater rim and mostly fell back inside.

At the time of writing, no changes in harmonic tremor are visible, and it is still unclear whether the start of strombolian activity heralds a new paroxysm - as it has done so 19 times before in the past 12 months - or not. The next hours and perhaps days will give an answer to it.
