If You Are Inside When the Shaking Starts...
Drop, cover and hold on. Move as little as possible.
If you are in bed, stay there, curl up and hold on. Protect your head with a pillow.
Stay away from windows to avoid being injured by shattered glass.
Stay indoors until the shaking stops and you are sure it is safe to exit. When it is, use stairs rather than the elevator in case there are aftershocks, power outages or other damage.
Be aware that fire alarms and sprinkler systems frequently go off in buildings during an earthquake, even if there is no fire.
If You Are Outside When the Shaking Starts...
Find a clear spot (away from buildings, power lines, trees, streetlights) and drop to the ground. Stay there until the shaking stops.
If you are in a vehicle, pull over to a clear location and stop. Avoid bridges, overpasses and power lines if possible. Stay inside with your seatbelt fastened until the shaking stops. Then, drive carefully, avoiding bridges and ramps that may have been damaged.
If a power line falls on your vehicle, do not get out. Wait for assistance.
If you are in a mountainous area or near unstable slopes or cliffs, be alert for falling rocks and other debris. Landslides are often triggered by earthquakes.
