Earthquake tremors in Manipur’s Ukhrul

mphal: Earthquake tremors were felt in Ukhrul in the northeastern state of Manipur on Saturday morning. The intensity of the earthquake was measured at 4.0 on the Richter scale. According to the National Center for Seismology, the epicenter of the earthquake was 10 km below the ground. At present, there is no news of any casualty or damage to property. Earlier, tremors were felt in UP’s Shamli late on Friday night, whose intensity was 3.2 on the Richter scale. Earlier on January 31, tremors of earthquake were felt in Manipur in the early morning. At that time its intensity was measured at 4.5 on the Richter scale. The National Center for Seismology, which informed about the earthquake, had told that Kamjong of Manipur was the epicenter of this earthquake. These tremors of the earthquake were felt at 10:19 in the morning. Its depth was 67 kilometers below the ground.

Earthquakes with a magnitude of less than 2.0 on the Richter scale are kept in the micro category and these earthquakes are not 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 and we do not feel it normally. Very light category earthquakes are of 3.0 to 3.9 magnitude, which are recorded 49,000 times in a year. They are felt, but do not cause any harm. Light category earthquakes are of 4.0 to 4.9 magnitude, which 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.
The earth is mainly made up of four layers…inner core, outer core, mantle and crust. The crust and the upper mantle core are called the lithosphere. This 50 kilometer thick layer is divided into several sections, which are called tectonic plates. The upper surface of the earth is made up of 7 tectonic plates. The main reason for the occurrence of earthquakes is the collision of these plates inside the earth. These seven plates keep rotating continuously and when they collide at some place, a fault line zone is formed there and the corners of the surface are folded. Due to the bending of the corners of the surface, pressure builds up there and the plates start breaking. Due to the breakdown of these plates, the energy inside the earth finds a way to come out, due to which vibrations are created, which we call earthquakes. Sometimes the intensity of vibration is very less, so we do not feel it or even if we do, only the earth remains shaken. Sometimes the intensity of the company is so high that it creates havoc.
