The Wall Street Journal this week reported the story of Sandra Ladra of Prague, Oklahoma. She was sitting in a recliner at home when the earthquake struck. As she describes it, the ground shook, her chandeliers “swung wildly” and the stone chimney in her house disintegrated, sending blocks through her roof and onto her legs. “‘I was screaming. I was trying to keep the blocks from hitting me’ said Ms. Ladra, 64 years old.
