Earthquake Safety & Preparedness
Drop, Cover, Hold On

During an earthquake, drop to your hands and knees, take cover under sturdy furniture, and hold on until the shaking stops.

Know Your Hazard Zone

Check if your area is near an active fault or within a liquefaction or EQ-induced landslide zone using the maps above.

Tsunami Awareness

If you are in a coastal area and feel a strong earthquake, move to higher ground immediately. Do not wait for official warnings.
