Morning Report
Report for the period 6 pm 7 November
to 7 am 8 November 1997


Seismicity has been dominated by elevated tremor on all stations since yesterday evening and up to the time of this writing. There was one pyroclastic flow signal at about 4:20 am today. This event generated an ash cloud which drifted North East and deposited very light ash in the northern part of the island. It is likely that this tremor is associated with rapid re-growth of the dome.

The high level of seismicity at the moment means there is a high possibility of more pyroclastic flows, which could travel down Ghauts on the northern flank of the volcano. In addition, there is a high chance that the volcano will start having explosions again. If these explosions do occur, they may do so with little or no warning at all. In these conditions 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. There is a lot of very fine ash in the air today and the weather is very dry. This condition makes it easier for the fine ash to be blown around. Residents are therefore reminded that they should wear dust masks, protect children, the elderly and persons with respiratory problems. Drivers are also reminded to be very careful to continue being courteous when driving on roads with ash. Everyone is advised to remain alert and keep listening to Radio Montserrat for any new information.
