It is called seismicity to the analysis of the number of earthquakes that occur in a given geographic region. Such a study records the various existing epicenters on a map, in addition to taking into account the frequency with which these phenomena occur. To do this, it uses a series of laws that help to understand and explain these events, such as the Omori's Law, the bath law, the Gutenber-Ritcher law, etc.
To understand the circumstances surrounding the earthquakes and tremors it is necessary to consider that the Earth crust It is fragmented into various plates that are in collision in some areas of the planet; This collision or collision is the cause that has formed the different mountain systems. Thus, for example, the Andes mountain range is the product of the collision between the Nazca plate and the South American plate.
A earthquake is a reorganization of the Earth crust as a consequence of a plate clash. This is followed replicas, or tremors smaller terrestrial magnitudes that occurred with a short time distance between them. Thus, earthquakes tend to be concentrated in specific regions of the planet, coinciding with the existence of fractures in the Earth crust.
The study of earthquakes helps reduce the damage that these can cause in human populations. On many occasions, high numbers of human lives have been skewed, in addition to large economic losses that are difficult to remedy both in the short and medium term. That is why governments in regions affected by the seismic activity they can only consider as an investment the study of the activity in the earth's crust, in order to take the most appropriate measures for its treatment. Experiences in the past have already been instructive enough to underestimate the consequences that these phenomena can cause.
