Natural disasters

Emergency numbers differ by country. This page uses 911, the number for the United States and Canada. Many other countries use 112, 999, or another number. Find the number for your country.

Natural disasters can strike with little warning, and the first minutes matter most. These guides tell you what to do during each kind of disaster and what to check afterward, in plain steps you can follow under stress.

If this is happening right now

  • Shaking ground: drop, cover, and hold on. See earthquakes.
  • Water rising: move to higher ground and never drive through floodwater. See floods.
  • Fire or heavy smoke nearby: leave early if officials tell you to. See wildfires.
  • A tornado warning: go to an interior room on the lowest floor. See tornadoes.

If anyone is hurt or in danger, call your local emergency number (911 in the United States and Canada, 112 across the European Union, 999 in the United Kingdom). The emergency numbers page lists more countries.
