Earthquake / Earthquake tremors in Jammu-Kashmir and Ladakh, magnitude 4.4 on the Richter scale

Earthquake: Earthquake tremors were felt in Jammu Kashmir and Ladakh. Its magnitude was 3.0, according to officials. There is no information about any damage in it. The Meteorological Department official said that the epicenter of the earthquake, which occurred at around 2.03 pm, was Ramban.

The depth of the earthquake was five kilometers below the ground. According to the administration, there is no news of any damage from anywhere. Earlier on Wednesday, tremors were recorded four times in the state within nine hours. Due to the tremors of the earthquake in the state, cracks appeared in many buildings. Five people were injured by falling debris. Two girl students of class 10 were also involved in this.

Actually there are many plates inside the earth which are displaced from time to time. This theory is called plate tectonics in English and plate tectonics in Hindi. According to this theory, the upper layer of the earth is about 80 to 100 kilometers thick, which is called the lithosphere. In this part of the earth, there are plates broken into many pieces which keep floating.

Normally these plates move at a speed of 10-40 mm per year. However, the speed of some of them is also 160 mm per year. The Richter scale is used to measure the intensity of an earthquake. This is called the Richter Magnitude Test Scale. Earthquake waves are measured on the basis of Richter scale from 1 to 9.

Earthquake risk varies from place to place in the Indian subcontinent. India has been divided into four parts Zone-2, Zone-3, Zone-4 and Zone-5 on the basis of earthquake area. Zone 2 is the least dangerous zone and Zone-5 is considered to be the most dangerous zone. All the states of North-East, Jammu-Kashmir, Uttarakhand and some parts of Himachal Pradesh come under Zone-5 only. From low altitude parts of Uttarakhand to most parts of Uttar Pradesh and Delhi come under Zone-4. Central India falls in Zone-3 with relatively less danger, while most parts of the South come in Zone-2 with limited danger.

The intensity of an earthquake is estimated by the waves of energy emanating from its center (epicenter). This wave that spreads up to hundreds of kilometers causes vibrations. Even cracks fall in the earth. If the depth of the earth is shallow, then the energy coming out of it is very close to the surface, which causes terrible destruction. The earthquakes that occur in the depth of the earth do not cause much damage on the surface. Tsunami arises when an earthquake occurs in the sea.
