In home in Randle (1 km N from epicenter) / MMI III (Weak shaking): I was laying on the couch when I heard and felt the roof, which is metal and not connected to the home, vibrate and then the house shake. The vibration lasted less than a second. My wife was outside when she thought she heard a distant boom and felt what she described as a change in air pressure,(ear popping feel).
