Activity at the Soufrière Hills Volcano is at a low level.

The seismic network recorded five rockfalls and two volcano-tectonic (VT) events this week.

The average sulphur dioxide measurement over three days this week was 591 tons per day with a maximum of 620 and a minimum of 565 tons per day. Unusual wind directions precluded measurement on four days.

Residents may have noticed the smell of volcanic gases as southerly winds, associated with the passing of Hurricane Irene, have blown the volcano's plume towards inhabited parts of Montserrat.

Brief clear views of the south-west part of the lava dome showed no significant changes.

Despite the low level of activity, sporadic pyroclastic flows will continue to 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.
