Montserrat Volcano Observatory


Morning Report
Report for the period 6 pm 12 November
to 7 am 13 November 1997


The seismic activity remained at a slightly elevated level last night with some small hybrid earthquakes and very few rockfall events throughout. It is likely that most of these are being produced on the new dome above Galways although there is also unstable older dome material on all sides of the volcano. This unstable material along with new dome material may collapse to form pyroclastic flows which could travel down ghauts on any flank of the volcano. A substantial dome collapse could also initiate further explosions. Everyone is advised to remain alert and keep listening to Radio Montserrat for any new information.
