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

The seismic network recorded sixteen rockfalls, three volcano-tectonic (VT) events.

The average sulphur dioxide measurement was 461 tons per day, with a maximum of 594 and a minimum of 332 tons per day. Gas measurements were not possible for the later part of the week owing to unusual southerly and south-easterly wind directions.

A small pyroclastic flow occurred in the February 2010 collapse scar on the morning of 11 May. The runout was about 1 km however a vigorous ash cloud rose to about 6000 ft and the ash cloud drifted to the north-northeast of the volcano. A little light ash fall was reported in Lookout village.

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.
