An earthquake can happen anywhere, however here is a list of some of the worst earthquakes recorded.

Effects and impacts of earthquakes
As you know, earthquakes can cause mass destruction of buildings, homes, roads, and highways, but they can also cause other natural disasters such as tsunamis (large waves caused by earthquakes in the ocean), avalanches and landslides. There is no determined amount of time it takes to completely recover from the destruction of an earthquake. It is documented that earthquakes, depending on the magnitude can level an entire city.
Be prepard. Tips on what to do before, during and after an earthquake
There is no real way to predict an earthquake. As discussed earlier, scientists are working on being able to provide information on when an earthquake will occur, however you can use the following tips to be ready for this type of natural disaster and what to plan for once the event has ended.
1. Build and emergency kit with things like first aid supplies, flashlights, batteries, and water.
2. Make a family communication plan, and practice earthquake drills often.
3. During an earthquake, take shelter under something sturdy, to be protected from falling objects and debris. Hold on to something and stay inside until the shaking stops. Remember there are always aftershocks from an earthquake that can cause more structures to collapse.
4. After, provide first aid where appropriate. Do not move any seriously injured people as this can further complicate any injuries they may have.
5. Wait for the all clear to return to your home. Be careful opening cabinets, as things may call from them.

1. A city in Chile moved 10 feet in the massive 8.8 magnitude earthquake Feb. 27, 2010
2. The moon has earthquakes. They are less powerful and not as frequent as the ones here on earth. Shouldn't they be called moonquakes?
3. Extracting oil from the earth can cause minor earthquakes.
4. An earthquake from side of the earth can shake the other side.
5. San Francisco moves towards Los Angeles at the rate of about 2 inches a year.
