Montserrat Volcano Observatory


Morning Report
Report for the period 16:00 16 February
to 07:00 17 February 1997
The current alert level is ORANGE


Activity at the volcano has been at a low level overnight. The volcano-tectonic earthquake swarm that began yesterday at 10.00 am continued until 5:52 pm and this was followed by low level volcanic tremor between approximately 9.00 pm and 3.00 am. A few small rockfall signals have also been recorded during the night.

The visibility is very good this morning, with the summit of the dome visible from the observatory. Observations will shortly be made from the east and a dome survey may be undertaken.

Despite the relatively low level of activity which has been experienced over the past week, the volcano is still quite dangerous. The eastern side of dome is still steep and unstable, so that 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.
