Experts know that a disaster is coming but they do not know when it will happen. They do know that it could cause a lot of damage. They think it will be worse than a hurricane. The disaster they are worried about is an earthquake.
There is a break in the earth’s crust (外壳). It is called the San Andreas Fault. The San Andreas Fault is in California. Many earthquakes happen along the San Andreas Fault. In 1989 there was a big earthquake on the fault. The earthquake was called the “Loma Prieta Earthquake”. Many people were hurt or died. Many buildings were ruined. Lots of people lost their homes. Roads and bridges were also damaged.
A large earthquake could happen in Southern California. Many small earthquakes have happened in the last year. Earthquake experts think that a large earthquake will happen there soon. They think a big earthquake will happen in the next few years.
The San Andreas Fault has many power lines stretched across it. There are water channels close to the earthquake fault. A large earthquake in Southern California would destroy energy and water supplies (供应). Lots of people would be without power or water for weeks. Buildings that have not been built strong enough would be destroyed. Not all hospitals would be able to help people who were injured. Many people would die or be homeless.
People need to be prepared. They need to know what to do if an earthquake happens. Everyone in California should have a survival kit at home. The emergency kit (应急箱) would include food and water. There should be medication and first aid supplies in the kit. A good survival kit will also have a portable radio, flashlights and spare batteries. All of the supplies in the kit should last at least 3 days.
