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 was at a very moderate level for the past 24 hours.

There were regular rockfalls and some very short lived pyroclastic flows, most of these travelled down the north and northeastern sections of the dome overlooking Tuitts, Whites and Mosquito Ghauts. Some ash plumes were formed reaching heights of 4000 feet and this was blown out to sea.

It was possible to see sections of the dome and Galways Wall from the South Soufriere Hill Occupation Post and it was observed that there has been little change in this area. During the 5 hour occupation of the post no rockfalls at all were seen which confirms that the activity has switched to the northern areas.

The seismic network only recorded three hybrid and two long period earthquakes yesterday (Sunday). Some COSPEC measurements were carried out yesterday to check sulphur dioxide content of the atmosphere, the results for Thursday and Friday were announced yesterday at 770 and 510 tonnes respectively.

The dome is still growing and remains dangerous, the alert level remains at ORANGE.
