Montserrat Volcano Observatory

Morning Update
Report for the period 16:00 08 October
to 07:00 09 October 1996

Seismic activity at the volcano has remained at a low level overnight with only a few rockfalls being experienced. Small rockfall signals has continued to be the only type of event recorded by the seismic network. Broadband tremor on the Gages seismic station, has been at a higher level than yesterday; this may be due to increased steam venting as a result of intermittent downpours of rainfall experienced during the night. One regional event was recorded at 00:35 early this morning.

Low cloud has prevented any views of the crater area this morning.

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.

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.
