5.6 EARTHQUAKE in Oklahoma? Story here. Nobody hurt, but another preparedness reminder.

UPDATE: More.

ANOTHER UPDATE: Reader Kevin Furr writes: “I felt it, sitting at home in Dallas 200 miles away! The wonder of the Internet — felt some slight rocking, so I got on Facebook and all my Arkansas friends were suddenly checking in babbling about houses and shelves shaking. I could pretty well estimate it to be in Oklahoma just based on social media!”
