The Volcanic Explanation
For The 24 Hour Period Ending 7 AM On Friday April 11, 1997
A Presentation Of The Government Information Services
In Conjunction With The MVO.

The current alert level is ORANGE

The activity at the Soufriere Hills Volcano has once again been low over the reporting period. Seismic activity has been in the form of mainly rockfall signals with just a few earthquake signals.

Early this morning there was a period of low amplitude tremor on all recording stations and this was followed by a large pyroclastic flow at 4.50 am.

Good visibility yesterday allowed scientists to observe the area around Galways Wall from the helicopter - it is obvious that the recent dome growth has pushed further southward towards the wall. The upper surface of this area is highly fractured and there are high temperature gas emissions from the cracks.

This morning (Friday) there is rain in the mountains and this will probably lead to more volcanic debris flowing down Fort Ghaut. There is very little visibility of the dome this morning.

The volcano remains active and dangerous, with a very large dome which could collapse at any time. People should exercise extreme caution and remain vigilant at all times. Ash levels are high and everyone is urged to wear their dust masks in ashy areas.
