Activity at the Soufrière Hills Volcano has been low this week.

Sixteen rockfalls events and forty six volcano tectonic (VT) earthquakes were recorded this week. Thirty six of these events occurred in a swarm over one hour on the 28 March. This was the largest VT swarm since February 2010

The average sulphur dioxide measurement this week was 471 tons per day, with a maximum of 1206 and a minimum of 266 tons per day.

There were no clear views of the dome this week.

Despite the low level of activity, sporadic pyroclastic flows can and do 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.
