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 all
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.
We are proud to announce a scientific discovery that has been made in close connection to one of our past tours on Santorini: A new absolute date for the great Minoan eruption on Santorini volcano has been published yesterday in the issue of Science Magazine (28 April, 2006). It confirms an early date for the eruption putting it at 1627-1600 BC with very good confidence.Read all

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).
The eruption at Augustine may be approaching its end.
Activity at Augustine declined to low levels during 7-14 April, with seismicity decreasing to slightly above background levels, and rockfalls and avalanches decreasing in frequency in comparison to previous weeks. Low-level eruptive activity continued, consisting of slow effusion of lava at the summit accompanied by small rockfalls and avalanches on the volcano's flanks. Satellite imagery showed a decline in thermal output consistent with the decreased activity. Sulfur-dioxide gas measurements showed continued high levels of magmatic gas emissions that may have been associated with degassing of lava at the summit of the volcano. Augustine remained at Concern Color Code Orange.
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 all
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 all

The activity at Ubinas volcano continues. Sixteen families from the southern Andean town of Querapi were evacuated to a village three hours away according to news reports. About 60 other residents had already been evacuated from the same village over the past three days. Between 40 to 60 livestock, including vicuna and llamas, died near the slopes of the crater, and many more were reported ill, probably from drinking acid-contaminated water or eating ash-coated grass.
Lascar volcano IN TheCentral Andes (Northern Chile) started erupting on Tuesday morning (18 April, 2006). A column of steam and ash rose to about 3,000 m (1,864 miles) above the summit crater.
Tugurahua's strombolian acitivity has been increasing lately; in particular, the Institute of Geophysics and Volcanology in Quito reported an episode of lava fountaining from the crater last Sunday.
