FRiend in Northridge didn’t even feel it.
I am up here on our family farm but lived in Downey for 32 years befor retireing 3 years ago; my wife is still at the Downey house, she’s still to young to retire (heh,heh).
She called me about it a little while ago, said it shook pretty good for about 30 seconds or more then rolled for a while longer. No damage in the house other than a couple of scared dogs and all is well.
I’m in Hollywood and didn’t feel it. So words like “huge” and “violent” went over my head.
There are huge and violence quakes … but this wasn’t one of them.
