Volcano Eruption in Japan on Tuesday, 13 March, 2012 at 15:15 (03:15 PM) UTC.


Sakurajima continued its second day of violent eruptions on Tuesday, spewing hot rocks and ash, but there was no major damage in the vicinity, the Japanese Meteorological Agency said. The agency said Monday's powerful eruption was the most forceful since 2009. The volcano is located in the southern prefecture of Kagoshima. The Meteorological Agency added that the volcano has been erupting steadily for the last two years, but the eruption on Monday turned violent, throwing 50-centimetre (1 foot 6 inches) rocks nearly 1.2 miles away, the furthest since 2009. In response, the Meteorological agency extended the eruption warning to residents living further away from the mouth of the volcano. The volcano has already had over 300 eruptions this year. Sakurajima volcano, one of Japan's more active volcanoes, resumed activity in 1955 and has been active ever since. Sakurajima volcano in Japan's southern Kagoshima prefecture erupts violently in what officials say is the most powerful since 2009, though there has been no damage so far.


Volcano Activity in Colombia on Saturday, 10 March, 2012 at 03:56 (03:56 AM) UTC.


The Nevado del Ruiz volcano, whose eruption 26 years ago killed around 25,000 people, is showing signs of activity after nearly 20 years laying dormant, said Colombian geological group Ingeominas Thursday. Early Friday morning, geologists completed an observational fly-over with the assistance of the Colombian Air Force, during which they photographed the Nevado del Ruiz volcano and noted "ash on the glacier, near the crater rim and on the eastern flank," as well as a 4,500 foot gas column at the mouth of the volcano. During the same day a seismic tremor was reported along with an increase in sulfur dioxide emissions. All of these factors signal that the volcano is heating up. Located about 80 miles west of Bogota, Nevado del Ruiz is an active volcano that produces pyroclastic flows, or swift currents of hot gas and rock that lead to destructive mudslides. There have been numerous eruptions over the centuries, with the most recent was on November 13, 1985.


Volcano Eruption in Russia [Asia] on Friday, 09 March, 2012 at 08:22 (08:22 AM) UTC.


Friday saw a new eruption of the Bezymianny volcano on the Kamchatka Peninsula in the Russian Far East. Earlier in the day, the volcano spewed ash up to 8 kilometers high, seismologists said, adding that the eruption does not pose a threat to population centers in the area. One of the most active volcanoes in the world, Bezymianny is located 350 kilometers northeast of the city of Petropavlovsk-Kamchatsky. During its most powerful eruption in 1956, the 2,800-meter volcano ejected about three cubic kilometers of volcanic debris in a very short time.

Volcano Eruption in USA on Friday, 09 March, 2012 at 04:02 (04:02 AM) UTC.


Monitors have detected what is described as a small explosion at the Cleveland Volcano in Alaska. The volcano is located in Alaska's remote Aleutian Islands, southwest of Anchorage. According to the Alaska Volcano Observatory, the eruption happened just after 7 p.m. Wednesday. The incident was similar to eruptions in December which sent small ash clouds into the atmosphere. But they were small enough to dissipate quickly, and did not interfere with air traffic. Photos of the latest explosion was masked by cloud cover so satellite imagery is unavailable.


Volcano Eruption in Ecuador on Monday, 05 March, 2012 at 03:33 (03:33 AM) UTC.


Ecuador's Instituto Geofísico (IG) reports an increase of Tunguarahua volcano's activity: Since last night (3 March), 4 explosions have been reported of moderate to large size. An explosion at 07:31 local time today produced an ash columnreaching about 4 km in height and drifting to the west - northwest. A second explosion took place at 09:11 (local time) and produced a strong shock wave that rattled the ground and windows in nearby areas. CLoud cover has prevented detailed observations, but with the help of thermal sensors, hot fresh deposits were detected on the flanks, suggesting they were the result of a pyroclastic flow. In the morning, the observatory post at Cusúa reported the presence of hot deposits on the upper flank typical for fresh pyroclastic flow deposits. Ash fall was reported from Choglontús, Manzano and Motilones areas before, and this morning ashfall reached the Yuibug area. The monitoring system has been recording variable seismicity and powerful tremor episodes lasting minutes to hours (which probably indicate rising magma), interrupted by short moderate to large explosion signals corresponding to the ash eruptions from the growing lava dome.
