Activity at the volcano has again been at a low level overnight. Rockfalls and small pyroclastic flows continue to occur from the active area of the dome. Long-period earthquakes are still occurring at above-background levels. Some of these events trigger rockfalls from the dome. The largest rockfall signal overnight was at 4:44 this morning. Moderate amplitude tremor is being recorded on the Gages seismometer.
Cloud is currently obscuring the summit of the volcano and the upper parts of the dome. Steam production is strong at the moment, due in part at least to the rain overnight. The steam plume has some ash within it generated from the rockfalls, and is stretching several tens of miles off to the west of Montserrat.
Whilst dome growth continues at the Soufriere Hills volcano, it remains dangerous. Pyroclastic flows and associated surges could occur at any time and without warning in the Tar River or White River valleys, and these and peripheral areas should not be entered at any time. Rapid changes in the style of activity and areas affected are possible. Visitors to Zone C should thus stay alert and are reminded to stay well clear of ghauts in the event of heavy rain. Masks should be worn in any areas affected by ash.
