11:41 AM: This was small enough and deep enough that it may have gone entirely unfelt, but a friend pointed this tweet out to Verne, who emailed us, so for the record: An earthquake of 1.4 magnitude – what’s considered a microquake – happened at 9:48 pm Christmas night, 17 miles beneath the West Duwamish Greenbelt, east of where SW Thistle ends. Here’s the Pacific Northwest Seismic Network page for it; here’s its US Geological Survey page (which includes a link for sending a report if you felt it); here’s a map. The quake was originally estimated at 2.0, but that was revised to 1.4 once it got an official review this morning.
2:11 PM: The microquake’s been reviewed again and now the epicenter has been shifted south to White Center, 14th SW just south of Roxbury.
