One dead after Central American Earthquake.

The United States Geological Survey recorded a Magnitude 7.3 Earthquake at a depth of 40 km, roughly 67 km offshore of the Nicaraguan coastal resort of Jiquilillo, slightly after 9.50 pm local time on Monday 13 October 2014 (slightly after 3.50 am on Tuesday 14 October, GMT). The quake was felt across much of Central America, from southern Mexico to Panama, and while there are no reports of any major damage one person was killed by a falling power cable in San Miguel in El Salvador.

 The approximate location of the 14 October 2014 Central American Earthquake. Google Maps.

Nicaragua and El Salvador are located on the southern part of the Caribbean Plate, close to its boundary with the Cocos Plate, which underlies part of the east Pacific. The Cocos Plate is being pushed northwards by expansion of the crust along the East Pacific Rise, and is subducted beneath the Caribbean Plate along the Middle American Trench, which runs parallel to the south coast of Central America, passing under the peninsula  as it sinks into the Earth's interior. This is not a smooth process, the plates tend to stick together, breaking apart again once the pressure from the northward movement of the Cocos Plate builds up to much, triggering Earthquakes.
