Activity at the Soufrière Hills Volcano has been low this week.

Nine rockfalls events and four Volcano Tectonic (VT) earthquakes were recorded this week.

The average sulphur dioxide measurement this week was 552 tons per day, with a maximum of 861 and a minimum of 370 tons per day.

Clear views of the dome this week revealed no major changes. Large steep, unstable and, in places, overhanging areas are present in several parts of the lava dome and pyroclastic flows remain likely, particularly to the north, west and east.

Despite the low level of activity, sporadic pyroclastic flows can and do occur without any warning. The Hazard Level is 3. There is no access to the terrestrial Zone C and only daytime transit access to shipping through the maritime extension of the zone.
