Port Blair: Earthquake tremors were felt in the Andaman and Nicobar Islands in the early hours of Thursday. According to the National Center for Seismology, an earthquake of magnitude 4.3 struck at around 2:29 am on November 10, 253 km south-east of Port Blair in Andaman and Nicobar Islands. The depth of the earthquake was 10 km below the ground. However, there is no report of any damage due to this earthquake. Earlier on September 2 and 3, earthquake tremors were felt in the Andaman and Nicobar Islands, whose intensity was measured at 4.9 and 4.4 on the Richter scale, respectively. A day earlier, around 1:58 am on November 9, strong tremors of earthquake were felt in the whole of North India including Delhi-NCR for 10 seconds. According to the National Center for Seismology, the magnitude of the earthquake was measured at 6.3 on the Richter scale, followed by Nepal. Its depth was 10 km below the ground.
6 people died in different accidents due to earthquake in Nepal. The main reason for earthquakes is the sliding or collision of tectonic plates inside the earth. There are seven tectonic plates inside the Earth, which are constantly rotating. When these plates collide at some place, a fault line zone is formed there and the corners of the surface are twisted. Due to the turning of the corners of the surface, pressure builds up there and the plates start breaking. Due to the breaking of these plates, the energy inside finds a way out, due to which the earth shakes and we call it an earthquake. An earthquake with a magnitude of less than 2.0 on the Richter scale is categorized as micro and its tremors are not felt. According to a report, more than 8000 earthquakes of micro category are recorded daily in the world.
Similarly, earthquakes of magnitude 2.0 to 2.9 are kept in the minor category. 1,000 such earthquakes occur every day. We usually don’t even feel it. Very light category earthquakes of magnitude 3.0 to 3.9 are recorded 49,000 times in a year. They are felt, but do not harm. Light category earthquakes with a magnitude of 4.0 to 4.9 are recorded on the Richter scale about 6,200 times a year all over the world. These tremors are felt. However, they also cause negligible damage. Earthquakes with a magnitude of more than 4.9 on the Richter scale are dangerous and most of the times they cause devastation. It depends on where the epicenter of the earthquake is located.
