Morning Update
Report for the period 16:00 10 October
to 07:00 11 October 1996

Seismic activity at the volcano has been at a relatively low level overnight, continuing the trend observed since October 1. Small rockfall signals continue to be the most frequent seismic event recorded. One long period and one hybrid event was also recorded by the seismic network. A single regional event occurred at about 05:27 this morning. High frequency broadband tremor on the Gages seismic station has been intermittent throughout the night with one period of increased tremor which began at 02:20 this morning and lasted for about 3 hours.

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

MVO scientists stress that the volcano is still in a highly dangerous state, despite the current low level of seismic activity. The October 1 dome is growing fast, and the rate of lava production is similar to that immediately prior to the 17-18 September explosion. Further pyroclastic flows are likely, and could trigger another explosive eruption with very little warning. The Tar River and Long Ground areas are extremely dangerous, and people entering them face a high risk of death.

The current alert level remains at Amber. Further details of the new Montserrat Alert System would be available in the newspaper today and would be officially launched at a media conference at 11:00 this morning. All residents of Montserrat are urged to exercise caution while visiting the evacuated zone and to become familiar with the new alert system and evacuation procedures.
