Yesterday 3:39 pm,I was seated in my workshop, yacking on the phone with my pal Dago when I felt like I was on the lake in our boat. I mentioned the quake to my pal & it was about 10 seconds later that he felt it & his wife heard it, whilst standing out side. They live 35 miles due north of my location, literally on top of the san andreas fault.
Everything is ok here for now, however socal is over due for another big one. The last big one here was in 94, it destroyed the I-5 corridor in the Newhall Pass & a large part of Northridge, Ca. I heard of a story yesterday, from a motorist travelling from San Felipe north to Mexicali, who saw liquefaction while it was occurring, most who see this don't live to tell the tale, ( big cracks in the roadway & surrounding terrain, that opened up after the quake with massive volumes of water surfacing out of the ground).
I have been in many quakes, 1971 Sylmar(6.1), 1981 Mammoth (6.4), 1987 Whittier Narrows (5-6?), 1994 Northridge ( originally reported at 7.1 then down rated for some unknown reason to 6.5, go figure?) Northridge was by far the most violent of them all, massive lateral shaking with vertical movement, I was bounced what seemed like a foot or so straight up out of bed. Not fun at all....
All of this is a reminder that our building codes are only a minimum requirement when designing & constructing a building. Build dense & strong, with lots of steel, thru bolted sections, over kill foundations, over sized post & beam type framing & so on..
R.V.s & dirt bikes are very useful when we have disasters that earthquakes can cause. :think:

P.S. our location is aprox 350 mile to the epicenter of yesterdays quake, not felt violently here but some substantial movement.
Cal tech reported the epicenter as 125 miles south east of T.J. That places it very near a location known as Laguna Hansen, It's in a range of large mountains that runs north-south in the middle of the baja peninsula. I hope that mikes sky rancho is still standing, It's another 125 miles south of that location.
