Eight killed by Earthquake in Peruvian Andes.

The United States Geological Survey recorded a Magnitude 4.9 Earthquake at a depth of 43.2 km in Acamyo Province in the Cusco Region of Peru, at about 9.35 pm local time on Saturday 27 September 2014 (about 2.35 am on Sunday 28 September GMT). The quake was felt across much of the region, and is reported to have caused the collapse of 45 homes and an eighteenth century church in the village of Misca, and led to the deaths of four adults and four children in the village.

Peru is on the west coast of South America and the western margin of the South American Plate, close to where the Nazca Plate, which underlies part of the east Pacific, is being subducted along the Peru-Chile Trench. The Nazca Plate passes under the South American Plate as it sinks into the Earth, this is not a smooth process and the plates repeatedly stick together then break apart as the pressure builds up, causing Earthquakes. As the Nazca Plate sinks further it is partially melted by the friction and the heat of the Earth's interior. Some of this melted material then rises through the overlying South American Plate, fuelling the volcanoes of Peru and neighbouring countries.
