The Izu Islands are a group of volcanic islands extending south and east from the Izu Peninsula of Japan. The USGS reported that the earthquake occurred at 12:06.
Earthquake occurred at a depth of 28 kilometers
According to the USGS, the quake occurred in Japan’s Izu Islands at a depth of 28.2 km. There is no news of any loss of life or property due to the low intensity of the earthquake.
Earthquake occurs due to collision of plates
This earth is mainly made up of four layers, which are called inner core, outer core, mantle and crust. The crust and the upper mantle are called the lithosphere. These are 50 kilometers thick layers, which are called tectonic plates. These tectonic plates keep on moving from their place, keep on rotating, keep on sliding. These plates usually move about 4-5 mm from their place every year. They can move from their place both horizontally and vertically. In this sequence, sometimes a plate moves closer to another plate and some moves away. During this, sometimes these plates collide with each other. In such a situation, an earthquake occurs and the earth shakes. These plates are about 30-50 km below the surface.
