What is seismology
seismology It is a branch of geophysics that is responsible for studying earthquakes, earthquakes or tremors that occur inside the earth and on the earth’s surface.
An earthquake, colloquially known as an earthquake, is a natural phenomenon characterized by a strong earthquake caused by the collision of tectonic plates, volcanic activities or geological faults. In reference to its structure, the place where the earthquake occurs is called the focus, its projection on the Earth’s surface is the epicenter, and the distance between the epicenter and the seismological station is known as the epicentral.
See also Earthquake.
Apart from studying the movements of tectonic plates, seismology is also responsible for analyzing the consequences produced by volcanic activities at the level of vibrations in the earth.
However, tsunamis, known as tidal waves, are a large wave that is produced due to a volcanic explosion or an earthquake that moves at high speed across the surface of the sea.
See also Tsunami.
On the other hand, seismographs They are instruments that allow recording the movement of the ground caused by a seismic wave. The seismograph amplifies ground movements on a strip of paper or sends them to a computer where the location, magnitude, and time of the earthquake, among other data, are studied.
Seismographs were created in the 19th century and have been perfected over time. It is noteworthy that in reference to this topic there is the seismological network which consists of analyzing the seismicity of a region. On the other hand, in each country it operates the Seismological Servicethe organization in charge of seismological observation in the national territory.
In reference to this topic, daily study is very important to obtain an advance in seismology that allows saving millions of people who are lost every year due to the damage caused by the previously identified telluric movements, as observed in the earthquake. of Nepal, suffered on April 25 of this year, which so far totals more than 7 billion victims.
