Montserrat Volcano Observatory


Morning Report
Report for the period 16:00 11 February
to 07:00 12 February 1997
The current alert level is ORANGE


The level of activity at the volcano has remained about the same overnight, with another swarm of volcano-tectonic and hybrid earthquakes. This swarm started at around 11:50 pm last night, and finished at about 6 am. Since then end of the swarm, a period of hybrid earthquakes and low-level tremor has begun. This sequence is typical of the recent seismic activity.

The crater area is obscured by cloud, so no observations have been possible so far.

The eastern side of dome is still steep and unstable. Further pyroclastic flows could occur with little warning. Residents are therefore reminded to remain alert and responsible at all times. This includes traveling with an ash mask, spending the minimum possible time in the evacuated zone and being prepared to take recommended action when advised. The Tar River and upper Galway's areas are extremely dangerous, and should not be entered under any circumstances. Zone E, which includes Corkhill and the airport, remains safe at this time.
