The level of activity at the volcano has increased somewhat overnight. Rockfall and pyroclastic flow signals continue to dominate the records, and these have been both more frequent and of higher amplitude in the past day than during the rest of the week. Long-period earthquakes continue to occur at above background levels. Several volcano-tectonic earthquakes have also been recorded overnight, one larger than any others seen so far in this swarm.
Presently the summit of the volcano is obscured by low cloud but it is hoped that this will clear to allow observations of the dome complex to be made. The increase in rockfall activity indicates the possibility of an increasing growth rate for 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.
