9:33 PM: Just got a text from someone in the Alki area saying they felt an earthquake that hit about half an hour ago in the Hood Canal area. Preliminary info indicates it was magnitude 4.2, which is stronger than the mild earthquakes which otherwise aren’t so uncommon in the region. The epicenter is described as west of Belfair. (The US Geological Survey map puts it under Hood Canal.) Will add anything more we find out.
10:26 PM: No damage reported, according to authorities near the epicenter:
Yes, Mason County, we had an earthquake! We had some alarm systems go off but no reports of slides or other damage as of now. Be safe!

So we’re going to take a moment to remind you again of your Emergency Communication Hubs – memorize the nearest one, so you know where to go in case of something big:
