Montserrat Volcano Observatory


Morning Report
Report for the period 16:00 30 May
to 07:00 31 May 1997
The current alert level is ORANGE


The level of activity has been fairly low overnight but regular rockfalls and small pyroclastic flows suggest that the dome is still growing. Between about 6pm and midnight the activity level was slightly elevated and signals from a number of small pyroclastic flows were recorded. There have been a small number of long period earthquakes overnight which have triggered rockfalls

The volcano is obscured by low cloud again this morning.

Small pyroclastic flows have already entered Tuitt's Ghaut and the continued growth of the dome makes it probable that more pyroclastic flows will enter Tuitt's and the other northern Ghauts. Large pyroclastic flows could occur with no warning in both the Tar and White River valleys.. Nobody should enter zones A and B and only essential visits to the central corridor should be made. The central corridor should not be used as a route to the airport.
