Morning Report
Report for the period 6 pm 19 December
to 7 am 20 December 1997


Seismic activity overnight has been lower than over the previous two days, with only occasional rockfall signals and a few hybrid earthquakes. Low amplitude tremor has occurred on the St. George's Hill Seismic station for the last couple of hours and is probably a result of the heavy rain in the early morning. Active growth apparently continues high on the Galways sector 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.
