The current alert level is AMBER

The level of activity at the Soufriere Hills volcano remains low however the north east face of the dome is becoming more unstable.

There have been some rockfalls and small pyroclastic flows but the seismicity has been low with just two earthquakes being recorded.

Yesterday and today there are good views of the dome possible and scientists took a long look at the north east face - there is evidence of steam venting and rockfalls from this face.

COSPEC measurements continue to be taken, throughout the week the results have been in the region of 160 tonnes per day of sulphur dioxide emmission.

The recent observations show that the dome is becoming increasingly unstable. It is already the largest it has ever been, and collapses could be imminent. There will be rockfalls and pyroclastic flows leading to large ash clouds so everyone should be vigilent.

No one should be in the vicinity of Long Ground, Tar River, and Galways as these areas are particularly dangerous.
