Activity at the Soufrière Hills Volcano is at a low level.
One rockfall and eleven volcano-tectonic earthquakes were recorded by the seismic network this week. Nine of these VTs occurred in 11 minutes on 17 January.
The average sulphur dioxide measurement over seven days this week was 263 tons per day with a maximum of 334 and a minimum of 164 tons per day.
No significant changes in the lava dome were observed this week.
Pyroclastic flows can still occur at any time 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).
