What to do in an earthquake
During an earthquake, it’s crucial 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. Here are the key points:
Drop, Cover, and Hold On:
Drop: Immediately drop down onto your hands and knees. This position prevents you from being knocked over and allows you to stay low and crawl to safety if necessary.
Cover: Use one arm to protect your head and neck, and if possible, take shelter under a sturdy table or desk. If no shelter is available, get down next to an interior wall away from windows. Stay on your knees and bend over to protect vital organs.
Hold On: Hold on to your shelter until the shaking stops. Be prepared to move with your shelter if it shifts.
