Earthquakes in California

According to the California Earthquake Authority, there are over 500 active faults in California. The CEA said most residents live within 30 miles of an active fault line.

Each year California is struck by about two or three earthquakes that are large enough to cause moderate damage to structures — with magnitudes of 5.5 and higher.

What should you do during an earthquake?

Actual shaking rarely causes injury. Injuries and death occur when walls and roofs collapse and glass and other objects fly or fall, especially when people try to move during the shaking, according to ShakeOut. No matter where you are, don't move if you can avoid it until you're sure it's safe.

When the shaking starts, ShakeOut advises the following:

◾ If you are inside a building, move no more than a few steps, drop to the ground, take cover by getting under a sturdy desk or table and hold on to it until the shaking stops.

◾ If outdoors, find a clear spot away from buildings, trees, streetlights, and power lines, then drop, cover and hold on and stay until the shaking stops.

◾ If driving, pull over to a clear location, stop and keep your seat belt fastened. Once the shaking stops, proceed with caution, avoiding damage that might have occurred.
