The activity at the Soufriere Hills Volcano has been reduced for the last 24 hours with no large pyroclastic flows taking place. However, the recent trend of earthquake swarms and tremors repeating every 13 to 14 hours continued. This regular pattern has been going on since last Saturday.
It was posiible yesterday to get some visibility of the dome from the helicopter, scientists noted that the new extrusion on the dome has extended further down the slope and has a blocky front. They also noticed that more material has fallen from the face to the base of the dome.
The top of Galways Wall has altered significantly in recent days with a deep slot having been cut through the top of the wall along the line of weakness. Material from the pre - September dome has now fallen through this slot and forms a grey deposit lying on top of previous rockfalls.
Yesterday (Tuesday) a GPS survey was undertaken at the Tar River, Windy Hill, Whites and Farrells stations, the results will be published later. This morning (Weds) there is very poor visibility because of early morning rain, however scientists are saying that the eastern face of the dome is very unstable and is likely to collapse at any time.
Public Works Dept are attempting to clear Fort Ghaut after the damage caused by floods over the weekend.
