Activity at the Soufrière Hills Volcano remains at a low level.
Four rockfalls and five volcano-tectonic earthquakes were recorded by the seismic network this week.
The average sulphur dioxide measurement over seven days this week was 287 tonnes per day with a maximum of 491 and a minimum of 182 tonnes per day.
On 28 January a small pyroclastic flow occurred on the western, Gages side of the dome. This had a run out of around 300 m, had no precursors and shows that the western side of the dome can still shed pyroclastic flows.
Lahars (mudflows) 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. In addition pyroclastic flows can still occur at any time without any warning.
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).
