Morning Update
Report for the period 16:00 11 October
to 07:00 12 October 1996

The volcano has been quiet overnight, with very few earthquakes recorded. There has been a high level of tremor recorded only at the Gages seismometer. This tremor has been seen a lot recently, and is thought to be due to steam and water movement within the volcano.

Low cloud has prevented any views of the crater area this morning, although the generally clearer conditions make make some observations possible later.

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.

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.
