The Volcanic Explanation
For The 24 Hour Period Ending 7 AM On Sunday February 16, 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 remains at a very low level. Over the last 24 hors there have been 35 volcano-tectonic earthquakes and 40 hybrid signals.

There was some rockfall activity over the Galways Wall and a small pyroclastic flow occurred yesterday evening in the Tar River Valley.

Visibility has been good over the recording period and it has been observed that some of the steep pinnacles on the eastern side of the dome have collapsed.

A helicopter survey of the dome was carried out yesterday (Saturday) to determine the growth rate of the dome. These results are still being processed.

Despite the low level of activity of late, the eastern face of the dome is very unstable and there could be further collapses causing pyroclastic flows and ashclouds.
