MONTSERRAT RECOGNIZES WORLD TSUNAMI AWARENESS DAY

Montserrat joins the rest of the world today, Sunday, November 5th, 2017 to observe World Tsunami Awareness Day.

Although, no activities were held locally today to commemorate the day, the Disaster Management Coordination Agency (DMCA) will continue its Tsunami preparedness education to establish Tsunami Ready Communities island-wide and a Tsunami Plan For Montserrat is currently being finalized to take to Cabinet for approval this year.

The DMCA believes the observance of this day will bring greater awareness to the dangerous nature of tsunamis and will help to improve public knowledge and preparedness.

Although, the topography in Montserrat has very few low lying areas, a tsunami could still impact the island depending on the intensity of the tsunami waves, the undersea features, and the land topographic elevations.

In the event, Montserrat should be impacted by a tsunami, the islandwide siren system installed will warn residents of a tsunami threat on the island. The sirens are tested daily.

Meantime, Director of the Montserrat Volcano Observatory (MVO) Roderick Stewart says in Montserrat, there have been three occasions when collapses of the dome entered the sea and generated tsunamis.

They are the December 26, 1997, collapse in White River valley that generated a small tsunami in Old Road Bay and the collapses on July 13, 2003, and on May 20, 2006, that, generated wave heights around the Tar River Valley up to 6-8 metres.

Mr Stewart confirmed that these tsunamis were very localised and would not have been seen at other locations.

He said the tsunami hazard in Montserrat that needs to be highlighted is from more distant sources – tsunamis generated by other volcanoes in the Caribbean Sea or generated by earthquakes.

“The Caribbean Tsunami Warning System will hopefully provide warning of these”, he stated. Continue reading

MONTSERRAT VOLCANO OBSERVATORY(MVO) WEEKLY REPORT FOR THE PERIOD OCTOBER 20TH TO 27TH, 2017

Activity at the Soufrière Hills Volcano remains low.
The seismic network recorded one volcano-tectonic earthquake this week.

Measurements of the SO2 flux were made using the helicopter on 25 October. A total of six traverses beneath the plume were carried out, with an average SO2 flux of 185 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.

Activity at the Soufrière Hills Volcano remains low.
The seismic network recorded no volcanic earthquakes this week.

No measurements of the SO2 flux have been made since 14 September.

The smell of volcanic gases has been noticeable at times during the week when the volcanic plume was blown 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.
