Seismic activity at the Soufriere Hills volcano during the night has been dominated by near-continuous low to moderate amplitude broadband tremor recorded at the closest seismic stations, especially the Gages seismic station. The tremor started around 17:00 on 23 April. The small, repetitive hybrid events, whose size is now very small, continue to occur in this tremor at a rate of about 1 per minute. Several rockfalls also occurred and a few signals interpreted as representing possible small explosions were recorded. The largest rockfall/explosion occurred at 02:07 this morning and produced a moderate-sized seismic signal on most of the nearest seismic stations.
Visibility during the early morning period from both the Observatory and Bramble Airport was very poor because of low cloud.
Scientists at the MVO still view the situation at the Soufriere Hills Volcano with grave concern and continue to urge that visits to the evacuated zone be kept to a minimum. The Tar River, Long Ground and Whites areas are extremely dangerous, and should not be entered under any circumstances.
