Ridgecrest earthquake rocks Southern California: Live updates - CNN

CNN's Scottie Andrew has this guide on how to stay safe before, during and after earthquake, according to the Department of Homeland Security, Earthquake Country Alliance and Red Cross:

Drop, cover and hold on: Try to avoid moving too much; if the quake is severe, it'll likely knock you to the ground.

Avoid windows: Flying objects could break through the glass and cause harm, so keep away.

Stay where you are: If you're in bed, stay there, but cover your face and neck with a pillow. If you're inside, don't run outside -- parts of the building's exterior could fall from overhead. If you're driving, stop your vehicle in an area clear of trees, buildings, overpasses or wires.

Don't take the elevator: Even if the power isn't out, the elevator could stop working if quakes continue. It's best to stay put, then take the stairs when it's safe to move.
