Japan Earthquake: Earth trembled again in Japan, the intensity measured at 6.1 on the Richter scale

Strong tremors of the earthquake have been felt in Hokkaido, Japan. Its intensity has been measured at 6.1 on the Richter scale. Earthquake tremors were felt at 2.48 pm (Indian time). The National Center for Seismology has given this information.

How do earthquakes happen?

The main reason for the occurrence of earthquakes is the collision of plates inside the earth. Seven plates inside the earth keep on rotating continuously. When these plates collide at some point, a fault line zone is formed there and the corners of the surface are folded. Due to the cornering of the surface, pressure builds up there and the plates start breaking. Due to the breakdown of these plates, the energy inside finds a way to come out, due to which the earth shakes and we consider it an earthquake.

Earthquakes with a magnitude of less than 2.0 on the Richter scale are classified as micro and cannot be felt. 8,000 earthquakes of micro category on the Richter scale are recorded daily worldwide.

Similarly, earthquakes with a magnitude of 2.0 to 2.9 are kept in the minor category. 1,000 such earthquakes occur daily, we do not even normally feel them.

Very light earthquakes of magnitude 3.0 to 3.9 are recorded 49,000 times in a year. They are felt but hardly cause any damage. Light category earthquakes are of magnitude 4.0 to 4.9 and are recorded on the Richter scale about 6,200 times in a year all over the world. These tremors are felt and household items are seen moving due to them. However, they cause negligible damage.
