The Volcanic Explanation
For The 24 Hour Period Ending 7 AM On Friday January 03, 1997
A Presentation Of The Government Information Services
In Conjunction With The MVO.

Over the last 24 hours the activity at the Soufriere Hills Volcano has been dominated by rockfalls and pyroclastic flows in the Tar River Valley from the Oct 1st dome (dome # 3).

The visibility over the reporting period was moderate and some views were obtained. It was noticed that the rockfalls were close to Castle Peak.

Some of the rockfalls caused ash clouds which drifted westwards with the wind. Some ash was reported 60 miles to the west of Montserrat at a height of 4000 feet.

The seismic stations recorded over 60 rockfalls, 1 volcano tectonic earthquake and over three dozen hybrid events.

Some COSPEC measurements were taken to check the level of gas in the atmosphere, the results showed very low levels.

The dome growth which started on Christmas Day continues at very high levels and the alert level remains at ORANGE. There should be no one in Zones A and B and only daytime access of Zones C and D for persons with a means of rapid exit.
