MONTSERRAT VOLCANO OBSERVATORY (MV0) WEEKLY REPORT NOVEMBER 9TH TO NOVEMBER 16TH, 2018

 

The seismic network recorded two rockfalls and 16 volcano-tectonic earthquakes this week. 14 of the VT earthquakes occurred in a very brief swarm in the morning of 13 November.

Measurements of the SO2 flux were taken from the helicopter on 9 November. There were eight traverses with an average flux of 209 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.
