The level of activity at the volcano has been moderate overnight. Rockfall and pyroclastic flow signals continue to dominate the records, with an increase in the number of suspected Tar River rockfalls as opposed to those in the White River. Long-duration signals were recorded on several occasions overnight and are probably the result of pyroclastic flows in the Tar River valley similar to the one witnessed just after 5 pm yesterday afternoon. Long-period earthquakes continue to occur at above background levels. A small regional earthquake was also recorded by the network, but no volcano-tectonic earthquakes occurred last night.
Presently the summit of the volcano is obscured by low cloud. MVO scientists will again try to get views of the upper flanks of the dome to more fully assess the current growth pattern of the dome.
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.
