Crawl Spaces : Good vs Bad

Slabs resist moisture but crack more easily when soil shifts. Crawl spaces work better on sloped properties but cost more. Slabs provide more durability, while crawl spaces hold up better in earthquake- and flood-prone areas.

Ideally, crawl spaces are safe during a tornado. However, they are not 100% safe. You should not be in a space as confined as that when there's the risk of house collapse looming above you. Also, the piping and wiring down there are dangerous if it's exposed and you are close to it.
