HERE’S WHAT YOU SHOULD KNOW ABOUT TSUNAMIS – TSUNAMIS ARE RARE, BUT ARE A POTENTIALLY DANGEROUS THREAT TO THE EASTERN CARIBBEAN

Montserrat is located in the Eastern Caribbean which is considered the most seismically active area along the Caribbean Plate.

Numerous volcanoes – both above ground and submarine – have the potential to cause landslides that generate tsunamis. This tsunami threat is in addition to earthquake-generated tsunamis along major faults and plate boundaries. Each year, over 1200 earthquakes are recorded in the Eastern Caribbean.

MONTSERRAT VOLCANO OBSERVATORY (MV0) WEEKLY REPORT JANUARY 4TH, 2019 TO JANUARY 11TH, 2019

Activity at the Soufrière Hills Volcano remains low.

The seismic network recorded three volcano-tectonic earthquakes this week

Measurements of the SO2 flux were taken from the helicopter on 10 January. There were six traverses with an average flux of 149 tonnes per day. The smell of volcanic gases was noticeable at times on 10 and 11 January as the prevailing winds blew the gas plume 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.
