Shaky ground in tornado alley

The shaking came in the dead of the night on a recent Wednesday morning, vibrations so intense that they startled Faye Sayre out of a deep sleep. Her bed was lurching up and down and back and forth — and Sayre, in her drowsiness, initially thought it was Gunner, her 180-pound English mastiff puppy, leaping on her mattress as if it were a doggie trampoline. “I thought, ‘Why is my dog jumping in my bed?’” Sayre recalled. “The bed was really rocking. ... And she doesn’t do that. She’s not excitable like that. She’s a very calm dog.” But as Sayre sat up to figure out what was happening, she noticed Gunner was sprawled in her usual spot on the floor next to her bed. The dog was looking up at her quizzically, and Sayre suddenly realized it wasn’t just her bed that was moving. The entire room was shaking.
