Montserrat Volcano Observatory

Morning Update
Report for the period 16:00 07 October
to 07:00 08 October 1996

Seismic activity at the volcano has remained at the low level experienced since 01 October. There have been a few rockfalls during the night, but these have been less common than yesterday. No volcano-tectonic earthquakes have been recorded.

Low cloud has prevented any views of the crater area this morning. Observations during yesterday confirmed that the October 1 dome is still growing at a high rate.

MVO scientists expect more rockfalls will occur as the October 1 dome increases in size. Further pyroclastic flows are possible. All indications are that the rockfalls and pyroclastic flows will be confined to the Tar River valley area but ashfalls may affect other areas. Dust masks should be worn at all times in ashy environments.

Despite the current low level of seismic activity, the volcano is still highly dangerous and the activity could change at any time. Individuals put themselves in extreme danger if they venture beyond Long Ground into the Tar River valley. All individuals passing checkpoints in whatever part of the island are reminded that they are entering areas which may become unsafe very quickly, and they should be on maximum alert. All residents of southern Montserrat are asked to ensure that they become familiar with the new alert system and evacuation procedures which would be published during this week.
