Volcano watch

"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

I will try to update this post daily with new volcano news starting from August 2011.

Comment by Howard on April 13, 2012 at 9:14pm: Turrialba Volcano Erupts, Costa Rica (April 12)

Thursday morning the Turrialbla volcano unleashed a new series of eruptions, with experts converging on the colossus to take a close look at the smoke emanations coming from its centre.

According to the Red Sismológica Nacional (RSN) and the Observatorio Vulcanologio y Sismologico de Costa Rica (OVISCORI) the activity does not present any danger, but will continue to monitor the volcano much closer.

The alert followed reports by area residents of hearing a large rumble and then the sighting of dark coloured smoke, produced by gas fumes from the volcano.

Last January the volcano became a concern for residents and experts following the emanation of white gas fumes.

Several RSN experts are on their way to the top of the volcano and the OVISCORI is keeping the national park closed and under a green alert.

Comment by Howard on April 13, 2012 at 5:50am: Mount Etna Erupts AGAIN! (April 13) -

The eruption spewed blood-red molten lava and grey and white ash into the air - is the 24th in a series that started in January 2011.

The Sicilian volcano has erupted three times in the past month, with regular 12 day pauses.

The main eruption is located at the south-eastern crater, not far from Zafferana Etnea village, but so far Italian authorities have not issued any warning of danger to houses and people.

The south-eastern crater, born in 1971, has been the most active in recent years.

In the recent past, lava flows have mainly damaged properties, but due to its slow speed the lava has not killed anyone.

Heavy ash emissions sometimes force the closure of nearby Catania International Airport.

For now, the airport remains open.

Mount Etna, has erupted for the fifth time this year.

Hot lava and ash spewed from the top into a valley nearby on the Italian island of Sicily.

The eruption happened on Sunday morning at 4am local time for more than an hour and a half.

Although the area around the volcano was covered by ash, it didn't affect planes traveling near it.

Comment by Howard on April 12, 2012 at 5:08am: Tungurahua Volcano in Ecuador Produces 4-5 km Eruption -
Apr 11, 2012

A moderately large explosion occurred at Tungurahua volcano today at 08:56 (local time). The eruption generated an ash column of 4-5 km height above the crater. The ash at lower altitudes drifted north-east, east and south-east the lower column, and ash from the upper parts of the eruption column to the north-west.

The explosion ejected incandescent blocks to distances up to 500 to 600 meters below the crater rim on the northeast side. Seismically the explosion was followed by a signal of high-energy tremor that lasted about 40 minutes.
The explosion was heard in villages near the volcano and at the volcano Tungurahua Observatory (OVT), located 14 km north-west of the volcano.

From approximately 09:30 (local time) the energy and height of the eruption decreased significantly, and the height of the eruption column dropped to less than 1 km.

Red alert over possible eruption of central Colombia Nevado del Rui...

Authorities declared a red alert in areas downstream the central Colombia Nevado del Ruiz volcano Sunday amid growing concerns an eruption is imminent.

According to Colombia's meteorological institute IDEAM, the highest alert was justified "for the rivers close to the Nevado del Ruiz volcano because of a change in eruption threat and the heavy rains that have presented themselves in this area."

Increased seismic activity forced local vulcanologists to maintain an orange alert for the past ten days which was heightened by the national authorities on Sunday after a further increase in measured activity.

According to IDEAM, the red alert is "preventive" and the volcano may decrease its seismic activity without coming to an eruption.

However, the red alert allows authorities to increase monitoring of the areas under threat of avalanches if the Nevado del Ruiz comes to erupt.

The city of Manizales, the capital of the Caldas department, falls under the area where the red alert was declared.

The most tragic eruption of the Nevado del Ruiz took place in 1985 when 25,000 were killed.

Comment by Sevan Makaracı on April 9, 2012 at 11:16am: APRIL 7, ANAK KRAKATAU, INDONESIA

On the morning of the 7th April 2012 Anak Krakatau started to produce small eruptions from the southern part of the crater. The eruption clouds only reached a height of 100-150meters and only contained small amounts of ash and only a little rockfall, the eruptions was not of a explosive character. The rest of the crater and its fumaroles are producing a continuous white cloud of steam/gas, rising to greater heights than the eruption clouds from the southern part of the crater. Additionally the southern/southwestern part of the outer part of the crater does now have fumaroles, indicating that magma is trapped under this part of the cone.

Comment by Howard on April 7, 2012 at 11:19pm: Unexplained Melting at the Askja Volcano Crater Lake (Iceland) -

The crater lake on Askja caldera has mysteriously become ice-free over the last month while lakes around it (that aren’t on volcanoes) and at lower elevations are still ice-covered – not to mention that normally the lake isn’t ice-free until June or July.

Comment by Planet Twelve on April 4, 2012 at 5:53pm: Significant increase in the activity of the volcano Nevado del Ruiz, Colombia

Tuesday Apr 03, 2012 19:02 PM | Age: 22 hrs

BY: T

Nevado del Ruiz seems to be getting closer to a new eruption. INGEOMINAS reports that during the last week, there has been a significant increase in the activity of the volcano, which can be summarized as follows:
- From March 27, there have been phases of volcanic tremor pulses related probably to deep magma movements
- Since the last week, there were seismic signals interpreted with rock fracturing, i.e. dike intrusions, located west of the active crater. Similar seismic activity was observed prior to the eruptions in November 1985 and September 1989, although this time it is less energetic.
- On March 29 at 10:54 local time, for a period of 25 minutes, there were over 135 earthquakes located south of Arenas crater at a depth of about 4 km.
- From 04:00 am local time on 31 March, there has been a significant increase in seismicity of events associated with fluid movements and fracturing of rock located in the active crater.
- SO2 emissions continue at high levels.

Mount Etna Erupts AGAIN - 5 Times So Far This Year -

Another VIDEO

"Europe's tallest volcano Mount Etna has erupted for the fifth time this year, spewing forth lava and ash.

"Stunning images show molten lava pouring down the mountain's side just after 4am local time. Local reports said it continued until about 5.30am.

"Ash from the eruption was thrown around the local area in Sicily, southern Italy, but there was no damage reported and air traffic was not disrupted."

ANOTHER LAVA DOME HAS FORMED, ALERT LEVEL RAISED

The alert level for a remote Alaska volcano has been raised again after scientists found another lava dome has formed in the crater in the last week.

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