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

The seismic network recorded two rockfalls and seven volcano-tectonic events and one hybrid this week.

The average sulphur dioxide measurement over five days this week was 422 tons per day with a maximum of 657 and a minimum of 289 tons per day.

There were no clear views of the dome this week.

Intense rainfall generated small lahars on the western flanks of the volcano on the morning of 11 October.

Despite the low level of activity, sporadic pyroclastic flows can 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.
