The current alert level is AMBER

Activity at the Soufriere Hills Volcano has once again increased over the last 24 hours. The seismic activity has been mainly in the form of a swarm of volcano-tectonic earthquakes and hybrid events. There were nearly 200 such events in the last 24 hours.

Several of the larger earthquakes triggered five pyroclastic flows over Galways Wall and these were recorded by the TV camera stationed there.

Yesterday (Friday) some EDM measurements were taken on what is known as the northern triangle (this is Windy Hill to Farrell's to St Georges Hill) and results show that it is remaining stable.

COSPEC measurements were taken yesterday to check sulphur dioxide levels in the atmosphere in the area between Foxes bay and Gingoes and the results will be published later today (Saturday).

Visibility has been very poor over the reporting period due to low cloud cover, however scientists are informing everyone that the dome is still growing and is steep and unstable. It is likely to have collapses at any time and this will result in pyroclastic flows.
