Earthquake in Diglipur
Earthquake tremors were felt in Andaman and Nicobar on December 29 last year. These tremors were felt in Port Blair. The National Center for Seismology had informed that the earth shook around 5:30 in the morning due to the earthquake’s tremors. Its intensity was measured at 4.3 on the Richter scale. The epicentre of the quake was 165 km southeast of the island.
Why does an earthquake happen?
Earth is made up of four layers. The inner core, outer core, mantle and crust core. The crust and upper mantle core are known as the lithosphere. This 50 km thick layer is divided into several sections. These are called tectonic plates. These tectonic plates keep moving in their places. When this plate starts moving a lot, it is called an earthquake. These plates can move from their place both horizontally and vertically.
How is the tremor of an earthquake measured?
Earthquakes are measured with a seismograph. The moment magnitude of an earthquake is traditionally measured, or the related and obsolete Richter magnitude is taken. An earthquake with a magnitude of 3 Richter is standard, while an earthquake of 7 Richter is causing severe damage. The earthquake not only causes loss of life and property, but it also causes a lot of damage to buildings, roads, dams and bridges etc.
To prevent this, earthquake-resistant houses must be constructed. Make a disaster kit consisting of radio, mobile, essential papers, torch, matches, slippers, candle, some money, and essential medicines. Immediately turn off electricity and gas in case of an earthquake. Not only this, do not even use the lift at all. Directly run to an open area and stay away from trees and power lines whenever tremors are felt.
