Activity at the Soufrière Hills Volcano is low.

There were five rockfalls recorded by the seismic network this week.

Sulphur dioxide measurements on 6 days this week gave an average output of 319 tonnes per day, with a maximum of 553 and a minimum of 200 tonnes per day.

Partial views of the lava dome on 26 July showed no major changes. A small pond of water was observed inside the new crater formed on 23 March in the collapse scar. Observations with the thermal camera show no high temperatures anomalies associated with the crater, although there were some strong fumaroles on its margin.

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).
