Activity at the Soufrière Hills Volcano is low.

There were no earthquakes recorded by the seismic network this week

The average rate of sulphur dioxide emission for 5 days this week was 456 tonnes per day, with a minimum of 223 and maximum of 713 tonnes per day.

Extensive cloud cover prevented any clear views of the volcano.

Heavy rain on 16 May generated a small lahar (mudflow) in the Belham valley.

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. 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.

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
