Northridge ‘94 (6.9) survivor here. You all in LA stay safe!
I remember it well -- the night the Devil had a nightmare. Compared to that, here in Camarillo today's seemed like one of the big Northridge aftershocks. It lasted a long time, 20-30 seconds, and seemed to grow in intensity before tapering off. Scared the hell out of the cat, and I found myself heading toward the back yard when it stopped!
