There’s a quake — still going on as I write this.
UPDATE: Initial tremor was sudden, followed by gentler shaking. It lasted long enough for me to start and publish the above post — probably 10-15 seconds in all. I will post USGS information as it becomes available.
Anyone else local feel it?
UPDATE x2: According to USGS, the quake was quite small. A 2.9 magnitude quake, centered 1 mile SE of Encino. I was guessing it was small, but I figured it was closer.
