An earthquake is caused by a sudden slipping or movement of a portion of the earth’s outer layer, called the crust. This sudden movement occurs along faults, or breaks in the earth’s crust along which blocks of earth move when built-up strain is released. The release of tension can cause the ground to shake violently, resulting in damage to buildings, roads, and utility systems over a wide area. Earthquakes can occur at anytime of the day or year with no warning.
Did you know that an earthquake occurs somewhere in Southern California almost every week? Most of them are too minor for anyone to feel them. However, much larger earthquakes have occurred in our area in the past, and will occur again sometime in the future. Major fault zones run throughout Orange County. If a large-magnitude earthquake were to occur along one of these faults today, the impact would be devastating.

If you're inside, stay inside. Take cover under a table or heavy piece of furniture.
If no protective cover is available, sit next to an interior wall and cover your head and neck with your arms.
Stay away from glass/windows or objects that could fall.
If outside, stay there. Move into an open area away from buildings or electrical wires.
If you're in a car, try to find a place to stop.
WHAT SHOULD I DO AFTER AN EARTHQUAKE?
Remember to assess the 3 'S's
SELF - Assess yourself for injuries. Falling debris during an earthquake is the number one cause of most traumatic injuries.
SURROUNDINGS - Assess your immediate area for other dangers such as exposed electrical wires, broken water mains, gas lines, etc
SURVIVORS - If it is safe to do so, help anyone in need of assistance. Render first aid to those in need of it.
Check gas, electric, and water lines for damage
Shut off the valves of any damaged utility lines
If you smell gas, leave the building immediately
Listen to the radio for news
