From Canada to Olympia – a rumbling shook western Washington on Sunday night. "Suddenly somebody jerked the couch really violently," said Ranate Hartog, manager of Pacific Northwest Seismic Network at the University of Washington. "It felt like but it was brief and it took a second but it was like, 'Oh it’s an earthquake.'" The earthquake's epicenter was near Marrowstone Island which is close to Port Townsend and Whidbey Island. It happened just after 7:20 p.m. The latest earthquake was below the threshold for sending an alert, Hartog said. If the quake exceeded magnitude 5 an alert would have given people near the epicenter a five seconds heads up. In the Seattle area, it would have been 11 seconds. Moments that would help people register what’s happening and find a secure place to take cover.
