It is defined as the movement or vibration of the ground, which is generally produced by the sudden release of energy accumulated for a long time due to displacement of rock masses in geological faults or by the displacement of the plates tectonic.
Last earthquakes in the world
What is an earthquake and what is its origin?
In general, the Earthquakes can have various sources of origin. and among the best known are the formation and reactivation of geological faults, displacements of tectonic plates, volcanic eruptions, by anthropic activity (mining, nuclear tests), seismicity induced by dams, possible meteorite falls, among others.

Why do earthquakes occur in our country?
He Peru It is located in the so-called Pacific ring of fire, at the same time the South American continent (Continental Plate) on whose western edge we are, is collided frontally with the Nazca Plate and as a product, the Nazca Plate (Oceanic Plate) enters below the Continental giving rise to the process called subduction. As a result of this collision, the Andean Cordillera has been formed, being considered worldwide the youngest dynamic structure of the tierra.
The plate collision occurs between two surfaces in continuous friction and give rise to the highest frequency of earthquakes in Peru, being here where the largest earthquakes of which history exists have been generated. He growth of the mountain range it also produces earthquakes and they are less frequent and smaller in magnitude, but they can be just as damaging as subduction ones.
It must now be understood that the oceanic plate It is found moving below the mountain range to distances so far from the coast that it is possible that it is below the city of pucallpa to a depth of 120 km on average and also produces major earthquakes that often cause damage to surface.
What zones or regions of Peru are the most seismic?
In Peru there are mainly two sources seismogenic. The first considers the entire area between the coastline and the Peruvian-Chilean trench, this source being the one that generates the largest number of earthquakes to depths of 60km and magnitudes as high like those of the earthquake Pisco 2007 (8.0 Mw).
These earthquakes have their origin on the surface of plate friction, Nazca and South America. The second source considers the regions where there are active geological faults that produce earthquakes with less frequency and moderate magnitudes (< 6.5 Mw) that can cause significant damage because their epicenters are close to cities and near the surface.
In this source the Moyobamba earthquakes of 1990 and 1991 due to the RiojaMoyobamba fault system. A third, less important source is the one that causes earthquakes at depth levels between 71 and 300 km.
These earthquakes have presented their foci at depths of the order of 120-250 km and magnitudes that have not exceeded the value of 7.5 Mw, being rarely felt on the surface with sufficient intensity to cause damage. The earthquakes, here it originates from the internal deformation of the Nazca plate that moves below the Andean Cordillera.
