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

The seismic network recorded three rockfalls and eight volcano-tectonic (VT) events.

The average sulphur dioxide measurement this week was 297 tons per day with a maximum of 398 and a minimum of 230 tons per day.  Fourier Transform Infrared measurements gave HCL/SO₂ ratios of 0.25, consistent with other measurements in the last year.

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

Temperature measurements were made of the 11 February 2010 pyroclastic flow deposits in the region of the old tower at Trants this week. Studies are ongoing but this work shows that these deposits are 194 ^oC at 3.1 metres below the surface.

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.
