Because earthquakes happen without warning, it’s important to take measures now to prepare. Because you don’t know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.

　　1. Water

　　A person needs at least 1/2 gallon(加仑) of water daily just for drinking. Store at least 1 gallon of water per person per day and be prepared for a 72-hour period. It is suggested that you buy bottled water. Keep bottled water in its original container and do not open it until you need to use it. Also, do check the “use by” date.

　　2. Food

　　It’s always a practical idea to keep a supply of non-perishable(不易腐烂的) food on hand. Have an enough supply of canned food, powdered milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.

　　3. Torch(手电筒) and spare batteries (电池)

　　Keep a torch beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks(泄露).Prepare a battery-powered radio and spare batteries. Most telephones will be out of order, so radios will be your best source of information.

　　4. Clothes

　　If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.
