Worldwide Volcano News and Updates:
Lava extrusion at Soufriere Hills volcano on Montserrat continues. Over the past week, dome growth has occurred over a sector extending from the south-west around to the north-east. The eastward-facing lobe has continued to grow on the northeast side of the dome and a central spine was observed on 28 April. Small rockfalls and pyroclastic flows continued to fall from the active eastern flanks of the dome, adding to the talus in the upper reaches of the Tar River valley. Rockfall activity has been accompanied by minor ash venting. Thermal images taken on 27 April indicated some very hot (in excess of 400 degrees centigrade) areas on the eastern flanks of the dome.Read more...
Mount Merapi started to show first signs of fresh magmatic actiovity, erupting a small amount of ash on Friday 28 April 2006. The alert level remains at its second highest level and volcanologist think that a major eruption is possible in the near future.
Bulusan volcano erupted on Sat. 29 April 2006 at 10:44 am (0244 GMT) spewing a column of ash about 1.6 km high. Ash fall occurred in surrounding villages. There were no reports of casualties or damage.

As KVERT reports, strombolian-to-vulcanian activity continued at Karymsky during the past weeks. Satellite imagery showed ash plumes extending ~40-145 km E and SE of the volcano, and a large thermal anomaly at the volcano's crater. Karymsky remained at Concern Color Code Orange.
Over the past weeks, weak strombolian activity continued at Fuego volcano, ejecting incandescent material ~50-75 m high, and gas plumes to ~150-200 m above the volcano. Incandescent landslides traveled down the volcano's S and W flanks. Lava flowed ~400 m S towards Taniluyá ravine.
As of 13 April, seismicity at Raoul Island had returned to normal and Green Lake's water level was dropping. Raoul Island remained at Alert Level 2 (minor eruptive activity).
Jorge Clavero Ribes from the Chilean Geological Survey (Sernageomin) and Juan Cayupi-Chilean Emergency Office (ONEMI) sent the following report about the recent eruptions at Lascar volcano:Read more... Lees alle
Dome observations suggest continued lava extrusion throughout the reporting period. Growth has occurred over a sector extending from the east around to the north. The eastward-facing lobe has continued to grow on the northeast side of the dome and a whale-back feature was observed on 18 April. Numerous small rockfalls continued to fall from the active eastern flanks of the dome, adding to the talus in the upper reaches of the Tar River valley. Rockfall activity has been accompanied by minor ash venting. Due to the unusual wind conditions, the plume has predominantly been transported to the north and northwest shifting to east on 20 April. Due to this and frequent rockfall activity light ashfalls have occurred over much of the island.Read more...
