The activity at the Soufriere Hills volcano further reduced over the last 24 hours. Seismic activity has dropped considerably with only a few signals being recorded.
Rockfalls have also dropped and there was only one pyroclastic flow in the last 24 hours. This happened mid morning yesterday (Saturday) and reached just past the Tar River Estate House. This caused wet ash to fall in Plymouth.
There was a brief period of visibility of the dome on Saturday and scientists noted that the new extrusion has blocks which have moved further downhill and that there has been constant ash production on the east side of the dome.
COSPEC measurements taken over the last few days show that the sulphur dioxide gas content of the atmosphere is 450 tonnes per day. This is a low figure and consistent with recent measurements.
Once again this morning (Sunday) the dome is under cloud so there is no visibility. However the dome is unstable and this will lead to pyroclastic flows.
