Montserrat Volcano Observatory

Morning Report
Report for the period 16:00 29 April
to 07:00 30 April 1997
The current alert level is AMBER

Activity at the volcano has continued at a low level overnight. The main form of activity has again been rockfalls and small pyroclastic flows from the active area of the dome complex above the Galway's Wall. The seismic network has continued to detect a number of long-period earthquakes, some of which triggered rockfalls from the dome.

Low cloud around the summit of the volcano is currently hampering views of the dome.

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.

Everyone is reminded that the siren system will be tested this afternoon between 3 and 6 p.m. A full test of the system is planned using the sirens in the different modes which are available.
