The Volcanic Explanation
For The 24 Hour Period Ending 7 AM On Sunday January 19, 1997
A Presentation Of The Government Information Services
In Conjunction With The MVO.

Activity at the Soufriere Hills Volcano over the past 24 hours has been very similar to that of the previous recording period.

A total of over 50 rockfall signals were recorded over the last 24 hours with additional hybrid and volcano - tectonic earthquake (VT) signals being recorded. The majority of VT's were recorded early yesterday (Saturday) and again early this morning (Sunday).

For most of the last day there has been low cloud cover over the volcano so very little visibility is possible. However, members of the GPS team have been going to the upper summit stations by helicopter and are reporting a few rockfalls. The team reoccupied the GPS networks over the last 24 hours and are concentrating their efforts on Chances Peak, Hermitage, Perches, Whites and Farrell's stations and the results will be avilable later this week.

The head scientist of the MVO Lloyd Lynch of the Seismic Research Unit in Trinidad told listeners to ZJB over the weekend that they can expect more pyroclastic flows and ash clouds over the coming weeks as the dome gets more unstable.

This morning the alert level remains at ORANGE and the W. H. Bramble Airport is open.
