The Earth’s crust is made up of seven tectonic plates. Wherever these plates collide with each other, there is a threat of earthquakes. When these plates rub against each other, a large amount of energy is released. Due to that friction, the earth above starts to shake. Japan is considered a frequent destination for this attraction. Vibrations are caused by the periodic energy released when the plates rub against each other. These are called aftershocks.

The impact according to the intensity of the earthquake on the Richter scale is as follows..

– An earthquake with a magnitude of 0 to 1.9 on the Richter scale- can only be detected by a seismograph.

– Mild earthquakes occur when recorded on the Richter scale of 2 to 2.9.

– 3 to 3.9 – will be the same as a truck passing by you.

– A 4 to 4.9 magnitude earthquake will shatter windows. Frames hanging on the wall may fall down.

– When there is an earthquake of magnitude 5 to 5.9 on the Richter scale, even furniture can shake.

– An earthquake of 6 to 6.9 on the Richter scale can cause the foundations of buildings to crack. Upper floors may be damaged.
