What is Earthquake definition/concept

An earthquake or earthquake is the movement of tectonic plates that manifest themselves on the Earth’s surface through tremors or displacements of the ground popularly known as earthquakes. The earthquake produces a sudden movement that can have different levels of intensity and duration and its consequences can either seriously affect an area or go unnoticed by the population.

Geologists analyze the hypocenter of an earthquake, that is, the place where the seismic waves started located in the earth’s crust and its epicenter, which is the point on the surface well above the place where the earthquake started and that will be affected by it. These analyzes are possible through information obtained by devices called Seismographs that are spread over the earth’s surface and are capable of detecting ground movements.

To assess the intensity of an earthquake, the Richter scale is usually used , a logarithmic system of base 10, that is, where each value attributed to the earthquake is multiplied 10 times. Therefore, intensity 3 earthquakes are not even noticed most of the time while intensity 5 earthquakes are capable of displacing furniture and breaking glass as they are 100 times stronger.

After the main earthquake, aftershocks of lesser intensity may occur during the next hours and days.

How to act during an earthquake?

What to do after the earthquake?

Check the condition of your home, as there may have been some kind of crack in the walls. Although everything is apparently in perfect order, it is possible that the interior of the cabinets becomes disorganized as a result of the movement.
