What to do in an earthquake?
It is important to know the right steps to protect yourself and minimize injuries during an earthquake. The California Department of Public Health (CDPH) provides detailed guidelines on what to do during such events. Here’s the key points:
Drop: It falls to your hands and knees immediately. This position prevents you from being knocked over and allows you to stay low and safely crave if necessary.
Cover: Use one arm to protect your head and neck, and if possible, take shelter under a sturdy table or desk. If shelter is not available, please go down through the window next to the interior wall. You can kneel and lean to protect your important organs.
Wait: Hold the shelter until the shaking stops. If the shelter shifts, be prepared to move with the shelter.
