The lava dome on Montserrat is again growing. The latest USGS/GVP activity report summarizes the recent activity: "MVO reported that pyroclastic flows from the Soufrière Hills lava dome occurred during 11-18 June. One of the largest pyroclastic flows traveled W down Gages Valley; others originated from within the collapse scar. A thermal camera showed several hot areas on the lava dome, likely exposed from rockfall and pyroclastic flow activity. On 28 June a small lahar descended the Belham Valley, to the NW. The Hazard Level remained at 3."

According to a local observer, the possibly first pyroclastic flow from Soufrière Hills since 11 Feb was observed on 1 March 2010. The lava dome was reported glowing bright at night.

NSAS and MVO published a comparision of two satellite images taken on 17 Mar 2007 and a recent one from 21 Feb 2010. The dramatic changes to the landscape including the extension of the eastern coastline near the former Bramble airport are spectacular. ...màs

A partial dome collapse occurred at Montserrat's Soufrière Hills volcano on Feb 11 at around 1 pm local time. Large pyroclastic flows travelled to the NE and reached the sea. A column of ash rose to at least 12 km. ...màs

MVO reported that during 8-15 January activity from the Soufrière Hills lava dome increased significantly. One explosion on 8 January and two on 10 January generated ash plumes that rose to altitudes of 5.5-7.6 km (18,000-25,000 ft) a.s.l. Ash fell in occupied areas to the NW, along with lapilli fall on 10 January. The explosions occurred from an area on the NE side of the volcano. Pyroclastic flows from column collapses moved rapidly NE (down Whites Bottom and Tuitts Ghaut), NW (down Tyers Ghaut and Belham Valley), W (down Gages Ghaut), and the SE (down the Tar River Valley). After the explosions activity decreased until 12 January, when cycles of increased numbers of rockfalls, pyroclastic flows, and ash venting were noted. ...màs [leer todo]
