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

The seismic network recorded four rockfalls and twelve volcano-tectonic (VT) events this week. Six of these VTs occurred in a small swarm on the morning of 18 November.

The average sulphur dioxide measurement over six days this week was 257 tons per day with a maximum of 407 and a minimum of 186 tons per day.

Partial clear views of the dome showed no changes in morphology.

Despite the low level of activity, pyroclastic flows can still occur without any warning. Lahars (mudflows) also remain a hazard and caution should be exercised crossing the Belham valley during rainfall.

The Hazard Level is 2. There is daytime access (8:00 am to 4:00 pm) to Zone C. Maritime zone W remains daytime transit only (boats may sail through the zone but must not stop)
