Morning Report
Report for the period 6 pm 9 November
to 7 am 10 November 1997

During the reporting period the level of seismic activity has again been relatively high.

Hybrid earthquakes have again dominated the activity. The hybrid earthquake swarm which began at 4.30pm on 8 November is continuing. The magnitude of these hybrid events has however diminished over night. It is possible that this hybrid earthquake swarm will probably eventually culminate in a series of pyroclastic flows.

The high level of seismicity at the moment means there is a high possibility of more pyroclastic flows, which could travel down Ghauts on any flank of the volcano. A substantial dome collapse could also initiate further explosions. If these explosions do occur, they may do so with little or no warning. Friths, Old Towne and Salem are not safe places to live.

In the event of an explosion or ashfall residents are reminded that they should not attempt to drive, but should get indoors and remain under the shelter of a strong roof. Residents are reminded that they should carry dust masks at all times and use them whenever there has been an ashfall. Everyone is advised to remain alert and keep listening to Radio Montserrat for any new information.
