The Volcanic Explanation
For The 24 Hour Period Ending 7 AM On Monday May 26, 1997
A Presentation Of The Government Information Services
In Conjunction With The MVO.

The current alert level is ORANGE

The level of activity at the Soufriere Hills Volcano remained at a high level yesterday (Sunday) and then lowered a little overnight.

There were two hybrid earthquake swarms in the reporting period, the second of which is still continuing as we write. The number of rockfalls in the last 24 hours increased which signifies an increase in the rate of growth of the dome.

The tiltmeter installed on Chances Peak is producing data which suggests a decrease in the rate of deformation in the last 24 hours.

The volcanic activity is now falling into a routine with hybrid swarms followed by sustained pyroclastic flows. This means that there will probably be more flows in the course of today (Monday) and as the wind is blowing from the south east any ash produced will probably blow into the safe zones.

Scientists are also warning that pyroclastic flows could break into Mosquito Ghaut, Tuitt's Ghaut and White's Ghaut in the very near future and thus everyone should stay clear of these areas.

The alert level remains at ORANGE which means there should be no visits into Zones A and B and anyone visiting Zone C should have a rapid means of exit. The central corridor road is dangerous and motorists heading for the airport should drive the northern route. All Montserrat's residents are asked to remain vigilant and stay tuned to ZJB Radio for updates.
