When there is an earthquake a tip to survive is to drop to the ground and hold your head and neck so you can protect your brain. We can measure earthquakes by using the machalli scale and the ricter scale. Earthquakes are created when the tectonic plates move away from each other ,towards  each other or they rub against each other. Most earthquakes occur  in the ring of fire. Another tip to survive is to not go near any windows and go under a door frame because that will be the last thing that brakes.
