MONTSERRAT VOLCANO OBSERVATORY (MVO) WEEKLY REPORT FOR PERIOD APRIL 13TH TO 20TH, 2018.

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

Measurements of the SO2 flux were made from the helicopter on 13 and 17 April. Five traverses were carried out on 13 April, with an average flux of 145 tonnes per day. Six traverses were carried out on 17 April, with an average flux of 248 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.
