A terremoto, Latin terra terrae 'land, earth', and motus 'movement', also called earthquake or earthquake is ajerk terrain that occurs by the collision of tectonic plates and release of energy in the course of a sudden reorganization of crustal materials to overcome the state of mechanical equilibrium.ORIGIN
The origin of earthquakes is in the accumulation of energy that occurs when, for rebalancing shift materials inside the Earth, from unstable conditions that result from volcanic and tectonicactivities, which are mostly due to the edges plate.
Although tectonic and volcanic activity are the main causes that are generated by earthquakes, many adverse factors can originate them:
*Accumulation of sediment, by: falling rocks on the slopes of the mountains, caves collapse.
* Changing rainfall regime, altering watersheds and river channels and estuaries.
* abrupt changes inatmospheric pressure by cyclones.
These phenomena generate events of low magnitude, which usually fall in the range of microdisk: tremors detectable only by seismographs.

Scale magnitude of body waves ().
seismological Richter Scale, also known as the local magnitude scale (ML) is an arbitrary logarithmic scale which assigns a number to quantifythe effect of an earthquake.
Scale seismic moment magnitude is a logarithmic scale used to measure and compare earthquakes. It is based on measurement of the total energy which is released in anearthquake. In 1979, Thomas introduced C. Hanks and Hiroo Kanamori as a successor to the scale Richte
Intensity scales seismological Mercalli Scale of 12 points, which was developed to assess the intensityof earthquakes as the effects and damage to various structures. Named after the Italian physicist Giuseppe Mercalli.
