Montserrat Volcano Observatory


Morning Report
Report for the period 6 pm 17 November
to 7 am 18 November 1997


Rockfall signals again dominated the seismicity overnight, and several of the events included a long period precursor. The long period signals are usually thought to be a result of degassing from the dome. The rockfalls are of similar size to those recorded over the last few days. Rockfall signals are interpreted to mean that the dome is growing and so more pyroclastic flows can be expected, these may travel down ghauts on any flank of the volcano. Everyone is advised to listen to Radio Montserrat for any new information.
