If you're at home during a tornado warning, what should you do with your windows?

Never open windows to "equalize pressure." That's a myth. Closed windows offer more protection from flying debris, but don't bother boarding them up. Just close them and head for a central room on the lowest floor.

What should you do if you can't escape the path of a landslide or mudflow?

Always leave the path if possible, but if you can't, FEMA advises curling into a tight ball and protecting your head. The flow can fell trees and crush cars, and landslides generally move much faster than humans can run.

If you're inside during an earthquake, you should ...

Don't exit a building during the shaking. Most earthquake injuries occur when people try to move around inside a building or try to leave. Only seek shelter in a doorway if you're sure it's load-bearing and strongly supported.
