Activity at the Soufrière Hills Volcano is low.
The seismic network recorded two VT earthquakes, one hybrid event, two long-period events and 13 rockfalls this week.
Sulphur dioxide measurements on eight days this week gave an average output of 654 tonnes per day, with a maximum of 1198 and a minimum of 295. The value was elevated following the ash-venting activity on 8 August, with average values of 911 up to 12 August and 397 thereafter.
There were no clear views of the dome this week.
Pyroclastic flows can occur at any time without warning on any side of the volcano, including Gages from where they can travel rapidly into Plymouth. Tracks across the Belham valley are frequently destroyed or heavily modified by flash flooding or lahars, and caution should be exercised crossing the valley during and after rainfall.
The Hazard Level is 2. There is no access to Plymouth or Zone V. 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).
