Recent Earthquake reports from USGS
It is interesting to plot the earthquakes in the area close to Barbados going back to the Brittons Hill tragedy earlier this year. USGS will provide notification by email of any earthquake it registers, anywhere in the world. The red balloons mark the approximate locations and give the date of their occurrence. The numbers 5 and 7 relate to the sizes of the earthquakes.
There was a large one of size 7.4 just off the north coast of Martinique on 29th November 2007 and a smaller one the day after nearby. However, there have been three others around Martinique, since September, two of them occurring in November, one the day before the big one on the 29th of November which was felt right here in Barbados.
Geologists tell us that the islands shown in the Google Earth screen capture above were literally lifted out of the water by a process of subduction of the Atlantic plate under the Caribbean plate. This process gives rise to earthquakes and created the volcanoes associated with the islands to the west of Barbados.
It would be interesting to look at the locations of earthquakes prior to Brittons Hill and locate them on the map above. The incident in Ellerton where part of a house disappeared into the earth on the 29th November may very well give us additional clues as to why the incident at Brittons Hill occurred.
Perhaps Mont Pelee will soon start acting up.
