Some thought their pets got the zoomies, others thought a car hit their home, but fortunately the impacts of the earthquake that shook the Puget Sound region Sunday evening ended there.

At 7:21 p.m., the Pacific Northwest Seismic Network recorded a 4.3 magnitude earthquake with the epicenter under Marrowstone Island, which is just west of Whidbey Island. It was at a depth of 35.5 miles.

Though no earthquake-related emergency calls were made, as verified by local law enforcement officers, many Facebook users across the island reported feeling the earthquake, which was also felt across Western Washington and British Columbia.

Megan Anderson, an earthquake geologist for the Washington State Geological Survey, said she felt the earthquake in Olympia. She explained that earthquakes are a common occurrence in Washington, with smaller, unperceivable shakes happening nearly daily.

She explained the quake was below a threshold at which seismographers would expect to see any damage whatsoever. She estimated that threshold to be at least a 5.5 magnitude quake on the Richter scale.

According to Anderson, the earthquake was too small to trigger ShakeAlert — a system managed by the U.S. Geological Survey that alerts people of an imminent earthquake — to send an alert. However, she still recommends signing up, as it can save lives by giving just enough time to seek cover.
