Morning Update
0700H 21 May, 1996


Volcanic activity at the Soufriere Hills volcano during the night continued at about same level observed during yesterday. Seismicity continues to be dominated by small- to moderate-sized rockfall signals and broadband tremor. Repetitive hybrid events have increased in frequency overnight and are now occurring at a rate of 4 events per minute. These events are still quite small and are only recorded by the Chances Peak seismic station. Low- to medium amplitude broadband tremor on the Gages seismic station have been continuous throughout the night.

Visibility during the early morning from the Observatory and Bramble Airport was 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.
