Magnitude 6.3 Earthquake in Lampa Province, Peru.

The United States Geological Survey recorded a Magnitude 6.3 Earthquake at a depth of 10 km, in Lampa Province in southern Peru, slightly after 5.40 pm local time (slightly after 10.40 pm GMT) on Thursday 1 December 2016. Around a hundred houses are reported to have been destroyed by the event, and at least 800 more have been damaged, as well as at least two schools and two churches.

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.

Witness accounts of Earthquakes can help geologists to understand these events, and the structures that cause them. The international non-profit organization Earthquake Report is interested in hearing from people who may have felt this event; if you felt this quake then you can report it to Earthquake Report here.
