Montserrat Volcano Observatory


Morning Report
Report for the period 16:00 10 November
to 07:00 11 November 1996
The current alert level is ORANGE.


Activity at the volcano has been at a high level overnight. The VT swarm that started at about 15:30 on 09 November has continued throughout the night. The activity increased during the night and peaked at about ten events per hour between 23:00 and 24:00. Activity has declined since then and there were between two and three earthquakes per hour at the end of the reporting period. Seventy-five earthquakes were recorded during the period with activity less intense than that experience during the swarms on 1-2 November and 4-6 November. All the VT earthquakes are located at shallow depths beneath the crater, similar to most of the activity in recent swarms. Variable period of seismic tremor was recorded on the Gages station throughout the night. No other seismic signals have been recorded during the night.

The volcano is overcast this morning and no clear views of the crater has been possible.

The MVO scientists are concerned about the VT swarms which have been experienced during the past week. There is a possibility of a rapid escalation of volcanic activity during the next few days and all residents are urged to always remain alert. The volcano is in a very dangerous state and all residents should follow the recommendations laid out in the alert procedures and listen to Radio Montserrat as they go about exercising their civic duty today.
