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.

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.
