Activity at the Soufrière Hills Volcano remains low.

The seismic network recorded two volcano tectonic earthquakes this week.SO2 flux measurements were taken by boat on 22 February and by helicopter on 23 February. The average flux values were 471 tonnes per day on the 22 February from 12 traverses and 364 tonnes per day on 23 February from 12 traverses.

Due to the large size of the lava dome, 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 can be 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 1. There is no public access to Zone V, including Plymouth. Maritime Zones E and W are daytime transit only between sunrise and sunset (boats may sail through the zone but must not stop). Anyone who ignores these restrictions is liable to be prosecuted.
