The Volcanic Explanation
For The 24 Hour Period Ending 7 AM On Thursday March 13, 1997
A Presentation Of The Government Information Services
In Conjunction With The MVO.

The current alert level is AMBER

The seismic activity at the Soufriere Hills Volcano has been quieter over the last 24 hours. However, the dome continues to grow and there are continued rock avalanches into the Tar River Valley.

There was a major earthquake swarm which started mid afternoon yesterday (Weds) and lasted until midnight. The peak of this activity was at about 8 pm last night.

Over the last 24 hours there have been no good views of the crater because of low cloud cover. However the TV camera at Galways is producing good pictures of the activity at Galways Wall and the continued rockfalls in this area. There has been a direct correlation between volcano-tectonic earthquakes and rock avalanches from the Galways Wall.

Some GPS and EDM measurements were taken yesterday and these results will be available later today (Thursday).

Scientists at the MVO are warning that the dome is becoming increasingly unstable and that further pyroclastic flows are imminent. Everyone is being urged to be vigilent and keep tuned to updates on Radio Montserrat.
