Activity at the Soufrière Hills Volcano is low.
The seismic network recorded nine rockfalls and one volcano-tectonic (VT) earthquake.
The average sulphur dioxide measurement this week was 618 tonnes per day with a minimum of 393 tonnes per day and a maximum of 1125.
Clear views on 14 April showed no changes to the new craters formed on 23 March.
Lahars (mudflows) occurred in several valleys on the western flanks of the volcano owing to heavy rainfall in the early hours of 19 April. Lahars (mudflows) remain a hazard and will increase in frequency as hurricane season approaches. Tracks across the Belham valley can be destroyed or heavily modified by lahars, and caution should be exercised crossing the valley during and after rainfall.
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.
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).
