Felt it in Foggy Bottom. At first I thought it was the AC or jackhammering. I'm happy I don't have to experience this often, like in California.
Erm... We don't experience this often in California... I definitely felt the '89 quake, probably felt one in the 90s and I think I felt a quake a few years ago. So I've felt them once per decade.
Further, CA has built relatively well to account for earthquakes and doesn't have a giant off-shore shelf waiting to collapse and drown us under a tsunami[1], so we have that going for us, which is nice.
