An Earthquake is an unexpected movement of the Earth’s surface.
It occurs when two parts of the Earth’s surface move relative to each other along a fault line. Due to tectonic forces ,the surface of the Earth starts vibrating and tremors are felt.
The point of origin of the Earthquake is known as FOCUS and the point directly above it on the Earth’s surface is known as EPICENTRE.
An earthquake warning system is a system of accelerometers, communication, computers, and alarms that is devised for regional notification of a substantial earthquake while it is in progress.
As of 2013, Japan is the only country with a comprehensive nationwide earthquake early warning system. Other countries and regions have limited deployment of earthquake warning systems, including Taiwan and Mexico.
Zone – II: This is said to be the least active seismic zone. Parts of Maharashtra and Uttar Pradesh fall under this zone
Zone – III: It is included in the moderate seismic zone. Andaman and Nicobar Islands, parts of Kashmir, Western Himalayas fall under this zone.
Zone – IV: This is considered to be the high seismic zone. Delhi, Jammu and Kashmir fall under this zone
Zone – V: It is the highest seismic zone. The region of Kashmir, the western and central Himalayas, North Bihar, the North-East Indian region and the Rann of Kutch fall in this zone.
The Indian subcontinent has a history of earthquakes. The reason for the high frequency and intensity of earthquakes is the Indian plate driving into Asia at a rate of approximately 49 mm/year.
India also has a long list of earthquakes. The Seismic Zone V and IV are most vulnerable to earthquakes, the following are some of the major Earthquakes in India:-
