The activity at the Soufriere Hills volcano during the night has been at a slightly higher level than that observed during the day time. Seismicity continues to be dominated by the occurrence of small- to moderate-sized rockfalls. Rockfalls around 05:30 this morning produced a small quantity of ash which was seen from the Observatory drifting through the Upper Gages area into Plymouth and environs. Intermittent low amplitude broadband tremor was also recorded at the seismic stations closest to the volcano. A few small long period events were also recorded. Two small volcano-tectonic earthquakes were located: one at a depth of less than one km beneath the crater and the other at a depth of 2.5 km beneath St. George's Hill.
Visibility during the early morning from the Observatory and Bramble Airport was poor but the situation is expected to improve during the day.
The present level of activity at the Soufriere Hills Volcano continues to cause concern to the scientists. The MVO continues 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.
