A earthquake is a tremor or one earth shaking due to internal causes . The term is synonymous with earthquake or seism , although in some geographical regions the concepts of earthquake or earthquake are used to refer to earthquakes of less intensity than an earthquake.
These movements are produced by the shock of tectonic plates . Collision free Energy while the materials of the earth's crust are reorganized to regain mechanical balance.
One of the main causes of earthquakes is the deformation of rocks next to an active fault, which release their accumulated potential energy and produce great tremors. Volcanic processes, hillside movements and sinking of karst cavities can also generate earthquakes.
However, experts in the field are also clear that an earthquake can occur as a result of a series of important changes in what is the river regime of an area or those that occur in relation to atmospheric pressures.
Among the main consequences that an earthquake can bring are ground ruptures, fires of varying severity, tsunamis or tsunamis and landslides of very different sizes. Given all this, the main tips to follow when an earthquake is suffering are the following:
If you are outside a property, you must be located in an open area, away from any type of building, and also not be placed near electric poles.
If you are inside an establishment or the house, the fundamental thing is to place yourself under the lintel of a door and always away from windows or any other object that can break and harm us. If we run out of light we have to go for flashlights and never for candles whose flame can cause a fire.
There are areas that have a greater tendency to suffer earthquakes. These are those regions where the concentration of forces generated by the boundaries of the tectonic plates makes the readjustment movements more frequent, both inside the earth's crust and on the surface of the land .
He hypocenter or seismic focus It is the inner point of the Earth where the earthquake takes place. If a vertical line is drawn from the hypocenter to the surface, we find the epicenter (the point on Earth where seismic waves impact with greater intensity).
Many are the earthquakes that have occurred throughout history throughout the world. However, among the most important is that of Valdivia (Chile) that took place in 1960 and reached a magnitude of 9.5.
They are followed in gravity and power by Aceh (Indonesia) in 2004 with 9.3; and that of Prince William Sound (Alaska) in 1964 which reached a value of 9.2.
The Richter seismological scale , baptized in tribute to the American Charles Richter (1900 -1985 ), is the most common logarithmic scale used to quantify the effects of an earthquake.
