What should we do at school when an earthquake breaks out？···

What should we do at school when an earthquake breaks out？First, we mustn't panic, all our actions must be according to the teachers' commands. If we are having a class,we should hide ourselves under the desks quickly. If we are on the playground, we must stay in-situ, without moving, squat, protecting our heads. We should keep away from the tall buildings and we mustn't jump off the buildings from upstairs.
We should help each other to overcome the current difficulties.
