Montserrat Volcano Observatory


Morning Report
Report for the period 16:00 01 April
to 07:00 02 May 1997
The current alert level is AMBER


The level of activity at the volcano overnight has continued at a low level. The seismic records have again been dominated by signals associated with rockfalls and small pyroclastic flows. The source area of these events is most likely the active area of the dome above the Galway's Wall. There have been some long-period earthquakes, some of which triggered rockfalls. Other types of earthquake activity has been very low.

Presently the summit of the volcano is obscured by low cloud but it is hoped that this will clear to allow observations of the dome complex to be made.

The volcano remains in a dangerous state and rapid changes in the level of activity are possible. Only essential visits should be made to Zone C, and people should wear ash masks when in ashy environments. All of Zone A, which includes Long Ground and St Patrick's, is very dangerous and should not be entered under any circumstances.
