"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

Unrest at Turrialba Volcano, Costa Rica Thursday, 26 January 2012

(Click on image for larger view.)

Turrialba is the eastern-most of Costa Rica’s active volcanoes. A series of small explosive eruptions began there in January 2010, the first substantial activity at Turrialba since the 1860s. The 2010 explosions were presaged by the opening of small gas vents (fumaroles) beginning in 2006. A new vent, located on the southeastern flank of the volcano’s West Crater, opened on January 12, 2012. According to the Observatorio Vulcanológico y Sismológico de Costa Rica, the new vent exhibited “a vigorous output of bluish gas at high temperature (T > 592°C) that generated a jet-like sound audible from the visitor lookout.” Activity since 2010 had been confined to a larger vent on the southwest flank of the West Crater, which continues to be the major source of emissions.

This image was acquired on January 21, 2012, by the Advanced Spaceborne Thermal Reflection and Emission Radiometer (ASTER) aboard NASA’s Terra satellite. The false-color image is a combination of near infrared, red, and green light. Healthy vegetation is bright red, while vegetation damaged by years of acidic gas emissions is brown. Bare ground in the summit craters is brown or gray.

The rock is very weak at the summit of Turrialba due to the intense rains of the region and the persistent hydrothermal activity at the summit. This means that new vents can open at the summit when pressure in the conduit is high enough to make its way through the weakened rock. The activity of January 12 was a pressure release at the summit through the hydrothermally-altered “rotten rock,” not a magmatic or phreatic (steam-driven) eruption.

Tungurahua volcano (Ecuador), activity update: new eruptions and lahars

IG reported a new episode of activity and increased seismicity from Tungurahua during 11-17 January. On 12 January ashfall was reported in Manzano (8 km SW), Cahuají (8 km SW), and Choglontus (13 km WSW). 
A lahar descended the Achupashal drainage, carrying blocks up to 1 m in diameter, and caused the road to Baños (9 km N) to be closed. Cloud cover prevented observations of the crater. On 13 January ash-and-gas emissions were observed, and ash plumes rose as high as 7 km (23,000 ft) a.s.l. and drifted W. Ash-fall was reported in Palitahua (6 km SSW) and roaring noises were heard in Cusúa (8 km NW) and Manzano. 
On 14 January ash emissions rose 500 m above the crater and drifted WSW; ashfall was reported in Choglontus, Palitahua, and Manzano. Clouds obscured views on 15 January; however ashfall was reported in Palitahua and Manzano. Lahars descended drainages in Juive (NW) and Pondoa (N), carrying blocks 10-20 cm in diameter.

COSTA RICA, TURRIALBA VOLCANO

.

New Alert At Turrialba Volcano

The alert for the Turrialba Volcano is back following Wednesday's activity that included the expulsion of ash and a slight tremor. The activity was confirmed by the Observatorio Vulcanológico y Sismológico Nacional (Ovsicori) that constantly monitors the volcano.

The spewing of ash and debris and the tremor was confirmed by areas residents.

OVSICORI experts are on site analyzing the causes of this new outpouring of ash that lasted some 20 minutes. In addition, the experts are involved in flyovers of the area....

CHILE, PUYEHUE VOLCANO:

Volcanic ash closes Argentina airport again

 

 A cloud of ash caused by a Chilean volcanic eruption forced authorities to shut Bariloche airport in Argentina days after it was re-opened, according to media reports. The airport was shut for seven months before being re-opened.

Puyehue volcano had erupted in June last year and since then, the number of foreign tourists has gone down, the report said.

According to a BBC report, all flights flying in and out of Bariloche, in Patagonia, were cancelled on Monday.
