What is an earthquake? Earthquakes are caused by the release of energy that generates waves that travel in all directions causing the shaking of the earth’s surface. Earth is not just one piece. It is made up of a jigsaw puzzle which is called tectonic plates. These plates are placed on a hot, partially molten layer of earth’s mantle. This is the reason why these pieces are continuously moving. An earthquake generates under the earth and this releases the energy across. The point at which the earthquake occurs under the earth is called hypocentre and the exact place above it at the surface of the earth is called the epicentre. Earthquakes are of 3 types, Convergent boundary, divergent boundary, and Transform fault. The most horrifying earthquake recorded till date was of a magnitude of 9.5 out of 10, this happened in Valdivia in Southern Chile in 1960.
