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

The seismic network recorded five rockfalls and ten volcano-tectonic (VT) events this week. Seven of these VTs occurred over ten minutes on 14 December.

The average sulphur dioxide measurement over four days this week was 742 tons per day with a maximum of 1782 and a minimum of 248 tons per day.

Multiple lahars (mudflows) occurred on the southern and western sides of the volcano on 10 December associated with heavy rainfall during a thunderstorm.

Despite the low level of activity, pyroclastic flows can still occur without any warning. Lahars (mudflows) also remain a hazard.  Tracks across the Belham valley are frequently destroyed or heavily modified by lahars, therefore caution should be exercised crossing the valley during and after 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).
