Volcanic activity at the Soufriere Hills volcano during the night was at a slightly higher level than during the latter part of yesterday. Seismicity continue to be dominated by small- to moderate-sized rockfall signals. The largest of these events was recorded at 20:35 on 23 May and was associated with light ashfall in Lover's Lane, Ryners and Gages. Intermittent low-amplitude broadband tremor continued to be recorded on the seismic stations closest to the volcano (Gages and Chances Peak). A few long-period events were also recorded during the period.
Visibility during the early morning from the Observatory and Bramble Airport was very poor; low cloud cover continue to obscure the top of the volcano.
The MVO still views the situation at the Soufriere Hills Volcano with grave concern and the scientists 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.
