Activity Report – 29 July 2008
There has been a partial dome collapse on the west side of the Soufriere Hills Volcano.
The collapse started at 11:27 pm local time on Monday 28th July 2008 without any precursory activity. Part of the western side of the lava dome collapsed generating pyroclastic flows that reached Plymouth and the sea.
There were also a few explosions from the dome during the collapse, with the largest at approximately 11:32 pm.
The height of the ash column was estimated at 12 kilometres (40,000 feet) above sea level.

Activity Report – 27 July 2008
Seismic activity at the Soufriere Hills Volcano has increased significantly. There was also a short series of eruptive events on the morning of Sunday 27th July 2008.
The seismic activity started to increase at approximately 1am on Saturday 26th July 2008 with renewed onset of hybrid earthquake activity. The numbers and size of the hybrid earthquakes slowly increased and peaked at about 9 pm on the same day, with a rate of around 15 events per hour. Seismic activity decreased over the next few hours, before starting to increase again at approximately 1 am on Sunday 27th July. This activity was mainly hybrid events, with a few long-period events. The activity peaked at around 3 am, at a rate of more than one event per minute, and continued at a high level until 9:35 am.
There was a short series of eruptive events on the morning of Sunday 27th July 2008. The first and largest event started at approximately 9:35 am and vented ash for about 15 minutes. The source of the ash could not be seen due to cloud cover, but was probably the Gages vent. This first event generated a non-energetic ash column which rose to about 2.5 kilometres (8,000 feet) above sea level. The ash cloud was blown to the west and north-west, and there was ashfall in Plymouth and St George’s Hill. There were no pyroclastic flows.
There were two other eruptive events in the next 45 minutes. These were much smaller, with ash clouds below 1.5 kilometres (5,000 feet) above sea level.
Seismic activity continued at a slightly reduced level following these eruptive events. If there is no further decline, more ash venting is expected.
