MONTSERRAT VOLCANO OBSERVATORY (MV0) WEEKLY REPORT SEPTEMBER 28TH TO OCTOBER 5TH, 2018

 

Activity at the Soufrière Hills Volcano remains low.

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

Data from the new permanent gas-monitoring stations, which are currently being tested, indicate that the flux remains in the range 100 to 400 tonnes per day. This week, measurements of the SO2 flux were taken from the DOAS station at Windy Hill on 3 October. This is an additional spectrometer which has recently been installed to supplement the existing DOAS network. This will allow measurements of SO2 to be captured when the wind blows the gas plume more towards the north, away from its usual position to the west of the volcano. Measurements from six scans at this station throughout the day on 3 October gave an average SO2 flux of 261 tonnes per day.

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.
