For The 24 Hour Period Ending 7 AM On Saturday February 08, 1997
A Presentation Of The Government Information Services
In Conjunction With The MVO.

The current alert level is ORANGE

Over the last 24 hours the seismic activity dropped a little at the Soufriere Hills Volcano. Once again there were periods of volcano-tectonic earthquakes followed by volcanic tremor. This activity caused some pyroclastic flows the heaviest of which was at about 4 pm yestarday (Friday).

This and other pyroclastic flows caused ash clouds leading to ash fall in Plymouth and points south. The ash reached heights of about 11,000 feet.

The activity further decreased overnight and for the first time in over a week a volcanic -tectonic earthquake swarm very early this morning (Saturday) was not followed by volcanic tremor.

As we write the dome is covered in cloud so no visibility is possible, however scientists feel that there is the possibility of a dome collapse on the eastern side of the dome. This area is very unstable and further pyroclastic flows from the area can be expected.
