Help me!!! it is urgent?

An earthquake is the shaking and vibration at the surface of the earth caused by underground movement along a fault plane or by volcanic activity. There are several important recommendations that you don’t need to forget during an earthquake.

First, be careful indoors during an earthquake. Drop, cover and hold on. Get under a table or bench, hold on to one of the legs and close your eyes. If there aren’t any tables or desks, sit against a wall away from things that might fall on you and away from windows, bookcases or heavy furniture. Wait in your safety spot until the shaking stops and then check to see if you are hurt. Move carefully and look out for fallen things.
