There has been an increase in rockfall activity in the last 24 hours at the Soufriere Hills Volcano.In addition there was some volcano-tectonic earthquake activity.

There have been further landslides from the top of the Galways Wall and some sections of the wall have been overtopped by fragments from the dome.

Visibility has been good throughout yesterday and today (Tuesday) and it is clear that the dome is still growing. The scar left by the January 20th collapse has now filled back in and the material in this area is higher than the October 1st dome (dome # 2).

EDM measurements were taken from Amersham to Chances Peak steps and the results will be announced shortly. In addition yesterday (Monday) there was also a dome survey carried out. This showed that material is being extruded at about 3 to 4 cubic metres per second.

As the dome continues to grow the possibility of dome collapse and pyroclastic flows greatly increases and there could be a major event over the course of the next few days.

The alert remains at ORANGE and the W.H. Bramble Airport is open as normal.

Scientists are urging everyone to keep clear of the Tar River Valley area and Long Ground as they are extremely dangerous.
