Walls of wells will have deep cracks.

There will be bright light in the sky;

Cows, dogs and pigs become too nervous to eat;

Mice run out of the fields looking for places to hide.

The water in the wells will rise and fall.

What do you think you would do first if the room started to shake?

• To my knowledge,the moment you realize you are confronted with an earthquake,you must keep cool and avoid being seized with panic. It is foolish of you to run aimlessly or to jump from your building. The best way of saving yourself is to take shelter where you are.

• 1) If you are in class, take shelter under a desk, shielding your eyes with one hand from the flying fragments of broken class.

• 2) If you are in a building, resort to narrow rooms, like kitchens, rest rooms,bathrooms, or the staircase rooms,for protection.

What do you think you would do first if the room started to shake?

• 3) If you are in a single-story house, run as far away from the house and other structures as possible when there is enough time for you to do so and when you can still keep your balance; otherwise, shield yourself under a bed/in a corner or attach yourself to a pillar/other concrete structures, covering your mouth and nose with a towel.

• 4) If you are in a workshop, cut off the electricity or the explosive/inflammable gas supplies first and then take shelter under a big machine. In the Tangshan earthquake, for example, all 30 workers in a weaving workshop survived the quake in this way except one, who was killed when running out of the building.

How should we prepare for earthquakes?

• Since earthquakes occur at any time without fore- warning signs, we should prepare for them as follows:

• 1) Regularly check and reinforce our houses, place heavy things in low positions, attach cupboards and cabinets to walls.

• 2) Keep in place survival supplies such as water, food, a radio receiver, a torch, extra batteries, a first-aid box, some rope and some warm clothing.

• 3) Arrange an auxiliary cooking and heating source; keep a fire extinguisher, a pair of heavy boots, and other proper tools to turn off gas and water supplies.

• 4) Make arrangements in case of an earthquake for family members to save and support themselves.
