Morning Update
0700H 09 June, 1996

Volcanic activity at the Soufriere Hill Volcano has continued at a similar level to yesterday. Small- to moderate-size rockfall signals has been recorded on seismic stations closest to the volcano. The largest rockfall signal was recorded at 20:22 on 8 June; very poor visibility prevented observation of any ash cloud that may have been associated with this event. The slight change in frequency and size of rockfall signals noted yesterday have been reversed during the night and many smaller events are now being recorded compared with fewer, larger events.

Low-amplitude broadband tremor has been intermittent for most of the night. One period of continuous high-frequency tremor occurred between 04:10 and 04:55 on 9 June.

The summit of the volcano was a bit more visible early this morning but low cloud cover continues to prevent any clear views from being obtained of the summit.

Scientists at the Montserrat Volcano Observatory continue to view the situation at the Soufriere Hills Volcano with grave concern. Visits to the evacuated zone should be kept to a minimum. The Tar River, Long Ground and Whites areas are extremely dangerous due to the frequent occurrence of pyroclastic flows in the Tar River valley. People should not enter these areas under any circumstances. If they do, they put themselves at direct risk of serious injury or death.
