VIDEO: 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.'" Hartog not only felt the earthquake, but she’s studying it.
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.
Researchers inside UW's Pacific Northwest Seismic Network lab have been analyzing earthquakes like Sunday's, which left no reported damage.
"Nobody felt really strong shaking, even though it might have been exciting," Hartog said.
The latest earthquake was below the threshold for sending an alert, Hartog said.
