After an earthquake, the recommended time to stay outside varies depending on the situation, but key safety practices are consistent:
- Remain outside in a safe, open area away from buildings, power lines, trees, and other hazards immediately after the shaking stops to avoid falling debris and structural collapses
- Expect aftershocks , which can continue for hours, days, or even longer. Aftershocks may cause additional damage, so stay vigilant and be prepared to drop, cover, and hold on again if needed
- Do not re-enter damaged buildings until they have been inspected and declared safe by authorities or structural engineers
- Stay outside or in a safe location for at least several hours after the main earthquake to monitor for aftershocks and secondary hazards such as gas leaks, fires, or tsunamis (if near the coast)
- Plan to be self-sufficient for at least 3 days, up to 2 weeks , as emergency services may be delayed or unavailable immediately after a major earthquake
In summary, after the shaking stops, stay outside in a safe open area away from hazards and do not return indoors until authorities confirm it is safe. Remain alert for aftershocks and be prepared to stay outside or in a safe location for hours or longer depending on the severity of the earthquake and local conditions
