The Volcanic Explanation
For The 24 Hour Period Ending 7 AM On Tuesday February 04, 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 activity at the Soufriere Hills Volcano was dominated by three episodes of high amplitude volcanic tremor during which there were pyroclastic flows.

The largest of these flows just reached the sea at the base of the Tar River Valley and generated ashfall on the west and northwest of the island. The ash reached heights of 8000 feet above sea level.

There were also some volcano - tectonic earthquakes as well as rockfall signals.

Most of the activity was above Castle Peak which finally disintegrated and eroded yesterday (Monday) so Castle Peak is no more.

A GPS survey was started yesterday at the Long Ground, Windy Hill, amd Harris stations, the results will be available later in the week.

Visibility is poor this morning (Tuesday) however scientists feel that as the eastern face of the dome is so steep it will collapse shortly leading to further pyroclastic flows and ashclouds.

Scientists are warning everyone to keep clear of Tar River, Long Ground, and the Upper Galways areas as they are very dangerous.

The alert level remains at ORANGE and health authorities are advising everyone to wear their dust masks.
