The most devastating tornadoes are usually the ones rated F5 or EF5. Tornadoes of this intensity have been known to obliterate entire neighborhoods and kill dozens. Examples of especially devastating tornadoes of such intensity include the Moore, Oklahoma tornado of 1999 which killed 36; the Hackleburg, Alabama of 2011 which killed 72; and the Joplin, Missouri tornado of 2011 which killed 158. Occasionally an F4 or EF4 tornado makes it onto the list as well, such as the Wichita Falls, Texas tornado of 1979 which killed 42, and the Tuscaloosa, Alabama tornado of 2011, which killed 64.
