The article says it was located in Big Bear (90 miles away from L.A.) - anyone in LA should be just fine. Doubt there was even damage - it was a 5.4 quake.
Gary and I "lived" in Big Bear for about 8 months in 1998! (In the R.V. There is a GORGEOUS R.V. resort up there).
We were in a 4.6 earthquake - first one I'd ever been in. Big Bear was the epicenter of that one too. Everything was shaking and rattling. Gary got up and opened the door (we have a steel frame) - it was so cool to watch the trees "bouncing." (Even though I was scared). It lasted for a few seconds.
The liquor store in town had a number of bottles fall off the shelves. That was the only damage then.
