How to measure earthquake magnitude

The “size” of earthquakes is commonly expressed in two ways-

An earthquake is the sudden release of strain energy in the Earth’s crust, resulting in waves of shaking that radiate outwards from the earthquake source. When stresses in the crust exceed the strength of the rock, it breaks along lines of weakness, either a pre-existing or new fault plane. The point where an earthquake starts is termed the ...Take cover under a heavy piece of furniture. Stay inside till the tremor stops. During the shaking of an earthquake, one must not leave the building because heavy and sharp objects can fall on you.
