Activity at the Soufrière Hills Volcano remains low.
The seismic network recorded thirteen (13) volcano tectonic earthquakes and two (2) rockfalls during the reporting period.
SO2 flux measurements were taken by helicopter on 09 February and by boat on 10 February. The average flux values were 484 tonnes per day on the 09 February from 12 traverses and 413 tonnes per day on 10 February from ten 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.Volcanic Activity Report: Graham Ryan, Director MVO
