EARTHQUAKE: Local microquake on Christmas night

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.

    I think I felt this in the N. Admiral area. It was so subtle though that I wasn’t sure if it was an earthquake.

    Was this bigger or smaller than Beastquake? :)

    Maps of the Seattle Fault show the southernmost branch of the fault runs just north of the epicenter.

      Wow, I looked up the map and just now learned the Seattle Fault runs right next to my house (and under the neighbor’s).  Good times!

        Yep.  Runs right under my house too.

    So the earth did move for you too!

    It’s wrong that I’m sorry I didn’t feel it, isn’t it?

Sorry, comment time is over.
