The Volcanic Explanation
For The 24 Hour Period Ending 7 AM On Sunday March 23, 1997
A Presentation Of The Government Information Services
In Conjunction With The MVO.

The current alert level is AMBER

The activity at the Soufriere Hills Volcano has continued at an increased level over the last 24 hours.

Yesterday (Sat) morning there were numerous rockfalls and pyroclastic flows and this was followed by an earthquake swarm which lasted up until about 11 pm last night. The swarm contained over 80 volcano-tectonic and hybrid earthquakes.

One pyroclastic flow over the Galways Wall produced an ash cloud reaching 5000 feet above sea level and this blew northwards depositing some ash as far north as Corkhill and beyond.

Yesterday and this morning (Sunday) the dome has been quite clear and scientists at the MVO continue to inspect it. The growth continues in the uppermost parts of the dome and it is obvious that the dome is now larger and higher than it has ever been before. It is currently about 150 feet higher than Chances Peak.

Scientists are warning that there will be a partial collapse of the dome in the near future and are warning that no one should be in the evacuated zones A,B, and C at night time. Residents are asked to remain vigilent at all times and to wear their ash masks in ashy areas.
