Activity at the Soufrière Hills Volcano remains low.
The seismic network recorded three rockfalls and five volcano-tectonic earthquakes this week. The rockfalls occurred following the heavy rains on 18th and 19th April and were most likely located inside the 2010 collapse scar.
Sulphur-dioxide measurements were not possible during the reporting period. The gas plume was blown northwards over inhabited areas at times during the week and the smell of volcanic gases was noticeable.
Following heavy rain on 18th and 19th April, there were lahars in the Belham Valley and other valleys draining the flanks of the Soufrière Hills Volcano.
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 are frequently 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.
