For anyone who might be wondering why a faint memory bell is ringing in your head when you hear the words "Moore, Oklahoma", but can't figure out the where or why, it's probably because it's the most "tornado famous" place on Earth. Two EF5's in a 14 year period, with seven more in the time between them. And the first biggie was a confirmed "old scale" F5 (no E) with an actual measured wind speed over 300 mph.
How scary is 300+ mph wind? It will lift and strip asphalt roads from the ground; and residential structures aren't just knocked over, or just flattened and scattered, they are completely erased. (Except for the concrete boxes below ground level that were once basements, there is absolutely nothing left.)
