What to do if an earthquake occurs
When an earthquake occurs, it is very important to know the proper steps to protect yourself and minimize injury. The California Department of Public Health (CDPH) provides detailed guidelines on what to do during such events. The key points are:
Drop, cover, and hold on:
Drop: Immediately drop to your hands and knees. This position prevents falls and allows you to stay low and crawl to safety if necessary.
Protect yourself: Use one arm to protect your head and neck and seek shelter under a sturdy table or desk if possible. If you don’t have a place to evacuate, get down next to an interior wall, away from windows. Get on your knees and lean forward to protect your vital organs.
Wait: Stay in your shelter until the shaking stops. If your shelter changes, be prepared to move with it.
