Seismic activity at the Soufriere Hills Volcano during the last 7 hours has remained at a similar level to that seen throughout the day. The generally low level has been interspersed with short periods of continuous tremor at most stations in the network. Hybrid-type earthquakes have been occurring at a rate of 1-2 per minute. This type of seismicity is indicative of continued dome growth. Numerous signals interpreted as the result of rock avalanches have been recorded throughout the evening.
Two larger events occurred at 20:24 and 22:23, possibly the result of small explosions in the crater. These events are similar to those which have been seen to produce ash plumes in recent days. However low cloud over the crater area prevented confirmation of the presence of ash plumes associated with these events.
The situation continues at a high level of alert. The apparent quiescence of the volcano should in no way be taken as a sign that the current crisis is over.
