Weekly Report 7 – 14 April 2017

Activity at the Soufrière Hills Volcano remains low.

The seismic network recorded two rockfalls and two volcano-tectonic earthquakes this week.

No measurements of the SO2 flux have been possible since 21 January 2017. The smell of volcanic gases was noticeable at times during the week. This was caused by unusual wind conditions, when the gas plume was blown towards the north over inhabited areas.

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.
