Montserrat Volcano Observatory


Morning Report
Report for the period 6 pm 18 December
to 7 am 19 December 1997


Seismic activity overnight has remained slightly elevated, with frequent small rockfall signals, and some hybrid and VT earthquakes. Active growth continues high on the Galways sector of the dome, producing a persisting plume of ash and steam. There has been again some light ash fall on island between Salem and St Peters, and further reports of smells of sulphur.

These effects are related to the active growth of the dome. This growth could switch quickly to other parts of the dome with little or no notice and pyroclastic flows could occur down any of the ghauts on the volcano. Everyone is advised to listen to Radio Montserrat for any new information.
