Seismic activity at the Soufriere Hills volcano during the night has continued at the same slightly reduced level seen during the day time. Small hybrid earthquakes continue to occur at a rate of about one every two minutes and their size is much smaller than a few days ago. Intermittent low amplitude broadband tremor was recorded at the closest seismic stations. Several rockfalls also occurred and a few signals interpreted as representing possible small explosions were recorded. The largest rockfall/explosion occurred at 22:16 on 24 April. Two small volcano-tectonic earthquakes and a long period event were also recorded but still have to be located
Visibility during the early morning period from both the Observatory and Bramble Airport was poor.
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.
