Earthquakes: Natural Destruction Phenomena
Hypothesis
The earthquakes are wave movements of the surface, have a lot of information about them, however scientists and people still have some doubts, can they predict or avoid?, These are questions that do not currently have a specific answer.
Purpose
The author’s purpose is to provide true and precise information about these natural phenomena, since for hundreds of years they have been given mythical causes and false information has been shared, in addition to this it is intended to inform to act correctly during the incident,since due to the bad information, damage and deaths in earthquakes increase.
The earthquakes have been present throughout the life of planet Earth, for the first civilizations of the ancient world these facts were totally unknown because the people of that time, had no information about these phenomena, so they were associated withMythical beings, gods, or extraordinary creatures, the Japanese, for example, believed that in the center of the earth lived a catfish or huge cat, and movements on the surface were the product of their shakes. The Aztecs had the belief that life ended every so often, this fact called "the fifth sun" which should end with a great magnitude earthquake, to delay this fact made sacrifices.
The first to study natural causes these movements were the Greeks, approximately in the 5th century.C, some philosophers claimed that water and humidity were the main causes, while some others said that they were produced by the air exit from the center of the earth, thus over the years new theories arose, some still relatedwith mythical facts, until in the seventeenth century scientists such as. Kircher, m. Lister and n. Lesmer resume research and again attribute natural causes to earthquakes.
In the mid -16th century. Von Humboldt did investigations and defended his theory by establishing that geological failures were the causes of the earthquakes, from that moment that subsequent investigations based on that theory which was the most accepted at that time, this was how the new areas of The science that were specifically dedicated to the study of these phenomena, psychology is a branch of geophysics that studies the aspects related to the recurrence of earthquakes, earthquakes or earthquakes, this is of the utmost importance, since although the earthquakes are not They can predict, you can know what are the seismic sources such as the sources of collapse, the explosives and the volcanic ones, the latter are the most frequent because there are several active volcanoes, various devices have been created that help us measure intensity, Behavior, duration among other characteristics of earthquakes, these earthquakes occur between 1 and 20 km below the earth, p or the general are of low magnitude and spread on the surface.
There are also the sources of impact that occur when a meteorite impacts the earth’s surface and generates seismic waves, although it is rare that this happens have registered some cases, such as Siberia on June 30, 1908.
A very frequent question is, can earthquakes be prevented?, For many years people have discussed the possibility of predicting natural disasters of this type, to be prepared in a risk situation, scientists have thought of several methods to avoid large earthquakes, it is said that if a type of type oflubricant several kilometers deep where the rupture areas are located, the magnitude of the earthquakes would be lower, however it is currently impossible to perform such maneuvers because there is not sufficient technological advances, in addition to that the costIt would be too high, however they do not rule out that in the not too close these methods can be used to avoid the great disaster that these seismic movements leave in their path.
It is very important to know what to do before, during and after an earthquake, this can make a big difference in the records of damage and deaths after the event, organizations must be formed, ask the authorities helped to establish evacuation routes, in buildingsWhere many people are concentrated, such as schools, hospitals, among other places with great population density, it is necessary to periodically review the state of the constructions to determine if there are no damage to the structure that can be harmful in a catastrophe.
During an earthquake it is important to always keep calm, many times it happens that someone panic and then the rest of the people, this is because seeing someone scared, other people also believe that they are in a true situation of risk, if you are in closed places, it should be evacuated with caution, avoiding running, shouting and pushing other people, this will favor rapid evacuation and prevent more accidents from being caused, you must also move away from structures or objects that may fall andCause some injury, such as trees, electricity posts, etc. After an earthquake, calm must be preserved, and be attentive to any new situation, since there are usually less magnitude replicas, in the event that it is in a several level building, it must be carefully evacuated, in places whereThe sea is close to the notices of the authorities, because a large earthquake can shake the sea violently and form a tsunami, these phenomena are also very dangerous, since waves of up to 200 meters can be formedhigh, destroying everything in its path.
