A large damaging earthquake could happen any time and can be followed by aftershocks that continue for a long time. Most earthquake-related deaths and serious injuries are caused by collapsing walls, and falling glass and objects caused by the shaking. In a major earthquake, masonry and glass can fall off buildings and into the streets.
During an earthquake
If you are inside, Drop, Cover and Hold – do not run outside or you risk getting hit by falling masonry and glass.
If you are outside, move away from buildings, trees, streetlights, and power lines, then Drop, Cover and Hold.
Stay there until the shaking stops.
If an earthquake is very strong and/or long and you are near the beach or coast, move quickly to higher ground in case a tsunami follows the quake.
