Earthquake or earthquake is called moving the surface of the earth. This occurs because of the seismic waves caused by the sudden release of energy in the earth's lithosphere. Earthquakes can be very violent and some have the ability to demolish people by damaging them and destroying the entire city.
The earthquake is measured with the seismometer, which is also called a seismograph. The horizontal magnitude of an earthquake is measured on a modest scale, or a related and obsolete Richter magnitude is taken. An earthquake of 3 or less magnitude Richter is often indistinguishable, while the earthquake of 7-Richter intensity causes severe damage to large areas. The intensity of the shaking is performed on the developed Mercalli scale.
On the surface of the earth, earthquakes are revealed by shaking or displacing the earth. When a major earthquake occurs at the epicenter of the coast, it causes adequate displacement on the shores of the ocean, which is the reason for the tsunami. Earthquake shocks can sometimes cause landslides and volcanic activities.
In the most general sense, the word earthquake is used to describe any seismic phenomenon, a natural phenomenon or a phenomenon caused by humans - which produce seismic waves. Often earthquakes come due to geological defects, large amounts of gas migration, mainly deep methane inside the Earth, volcanic erosion, landslide and nuclear tests are the main drawbacks.
