Do NOT go outside．You could get injured from falling glass or parts of buildings．If you are outside, stay away from buildings and power lines(输电线)．
Stay under a desk, table, or other strong furniture．Hold on to it．Or stay in a corner of the building．Cover your face and head with your arms and cover your mouth with a towel or clothing．Stay inside until shaking stops and it is safe to go outside．
Keep away from windows, pictures or advertisements on the wall or the building, and anything else that could fall and hurt you．Most people get injured by falling things during an earthquake, not by the shaking itself．
Also keep away from a fire．You could fall down and burn yourself on the fire．

Have you ever heard an echo of your voice?
An echo is a reflected(反射)sound．Stand in a very large, empty hall with nothing on the walls．Then shout．The sounds you make will hit the walls and come back to you．The walls reflect the sounds．These reflected sounds are called “echoes”．
We can use reflected sound to make sound travel farther．Hold a watch about fifty centimeters from your ear．You cannot hear it．The sound of the watch travels a short way in all directions．It does not travel as far as your ear．You can make it travel to your ear by using a roll of cardboard(纸板筒)．
Make the roll of cardboard about fifty centimeters long．Put one end over your ear and hold the watch at the other．Now you can hear the watch because the sound has not gone in all directions．It is reflected down the roll to your ear．
A megaphone(喇叭筒)works in the same way．It makes sound travel farther．It reflects the sound into a beam which can travel a long way．In the ship, the sailor uses the megaphone to make his voice travel．Without the megaphone, his voice cannot travel far．
We use reflected sound in many ways．We use it to measure the depth of the sea, for example．Among the animals, bats and whales use reflected sound to tell them where they are and what things are near them．
