A Presentation Of The Government Information Services
In Conjunction With The MVO.

The current alert level is AMBER

There has been very little change in the style of activity at the Soufriere Hills Volcano over the last 24 hours. Mainly this consisted of rockfall and small pyroclastic flows and some long period and volcano-tectonic earthquakes.

The volcano-tectonic swarm finished mid morning yesterday (Thursday)and all together there were 38 earthquakes at depths of about 3 kilometres below the surface.

There were good views possible yesterday and some clear views of the dome obtained. The dome is obviously still growing and the southwestern face the most active. An EDM survey of the northern triangle was possible yesterday and results will be announced later today (Friday).

Early this morning there was a large rockfall over the Galways Wall and this pattern of activity is expected to continue. For this reason no one should visit the Tar River or White Valley regions - they are extremely dangerous.
