Part of the terror of an EF5 tornado like the one that hit Moore, OK is the notion that nothing above ground can survive a direct hit of 200 mph winds that rip homes off foundations.
But that’s not exactly true. Above ground storm shelters held up exceptionally well in that tornado and could be a better choice than a traditional underground storm cellar, said Larry Tanner, a research associate at the National Wind Institute at Texas Tech University.
Tanner was among a team of researchers from the institute that toured the damaged areas after the Moore tornado. They examined how different types of structures held up in the storm, with particular attention given to storm shelters.
