Caribbean seismic activity

[cycloneye]

Here is a summary of the 6.4 quake that occurred north of PR.

Tectonic Summary


The January 13, 2014 M 6.4 earthquake north of Puerto Rico occurred as a result of oblique-thrust faulting. Preliminary faulting mechanisms for the event indicate it ruptured either a structure dipping shallowly to the south and striking approximately east-west, or a near-vertical structure striking northwest-southeast. At the location of this earthquake, the North America plate moves west-southwest with respect to the Caribbean plate at a velocity of approximately 20 mm/yr, and subducts beneath the Caribbean plate at the Puerto Rico Trench. The location, depth and mechanism of the earthquake are consistent with the event occurring on this subduction zone interface.


While the Puerto Rico Trench is known to be a significant seismic hazard, and is capable of hosting M8+ earthquakes, moderate-to-large events on the subduction zone are rare. Over the past century, three such events have occurred nearby to the January 13, 2014 earthquake – a M 6.6 event in 1915, just to the east of the 2014 event; a M 7.0 earthquake 70 km to the west in 1917; and a M 7.6 earthquake in 1943 just northwest of the 2014 earthquake. Two earthquakes occurred in the Mona Passage approximately 100 km to the southwest of the 2014 earthquake in 1916 (M 7.0) and 1918 (M 7.3), while the 1946 M 7.9-8.0 Hispaniola earthquake struck 230 km to the west, also on the North America slab interface. The July 1943 North Mona Passage earthquake did not cause significant damage in Puerto Rico, though it did spawn a small tsunami, and was the first in a series of large events in the broader northern Caribbean region between central Hispaniola and Puerto Rico over the following decade, including the larger 1946 earthquake. The 1946 event is known to have caused significant damage in both Hispaniola and Puerto Rico, including destruction from a subsequent tsunami.

Looks like our daily newspaper "FranceAntilles" have numbers up to 7.0 quake east of Martinica.

A magnitude 6.3 earthquake felt Friday morning in Guadeloupe.

http://www.microsofttranslator.com/bv.a ... 269242.php

A strong earthquake of magnitude 6.3 on the Richter scale was recorded this Friday, at 7:01 and identified of tectonic origin.
The epicenter was located at 117 km northeast of La Désirade, 11 km from depth. This earthquake has been well felt in the nearest affected areas, but do not appears to have brang damages. A second quake, magnitude 5 on the Richter scale, was felt ten minutes later. Other aftershocks could occur. A call for vigilance at sea is launched.

Here is a report of these 3 earthquakes who have occured in the same day in Guadeloupe. Something to keep an eye if things continues to shake roughly... Islanders be on your guard.


More than 20 aftershocks to the strong earthquake Friday morning
http://www.microsofttranslator.com/bv.a ... 269242.php

A first quake, relatively strong because of magnitude 6.3 on the Richter scale, was recorded this Friday, at 7:01 and identified of tectonic origin. The epicenter was located at 117 km northeast of La Désirade, 11 km from depth. This earthquake was widely felt by the people of Guadeloupe and Martinique, but appears to have not caused damages.
It was followed by more than 20 earthquakes, recorded by OVSG (volcanic and seismological Guadeloupe Observatory). A second shake , magnitude 5.2 on the Richter scale, was felt eleven minutes later. Other aftershocks have occured , the vast majority of low magnitude and not felt. But two have proved somewhat stronger, one at 830 AM, magnitude 5.4, the other at 834 AM magnitude 5.2.
