Activity at the Soufrière Hills Volcano is at a low level.

The seismic network recorded five rockfalls and six volcano-tectonic events this week.

The average sulphur dioxide measurement over six days this week was 260 tons per day with a maximum of 368 and a minimum of 174 tons per day.

There were no clear views of the lava dome this week due to low cloud.

Heavy rainfall on 22, 23 and 25 July caused lahars in several valleys around the volcano.

Despite the low level of activity, sporadic pyroclastic flows will continue to occur without any warning. The Hazard Level is 3. There is no access to the terrestrial Zone C and only daytime transit access to shipping through the maritime extension of the zone.
