We just left Ca.  July 7 and are now back in New Mexico.  We were there for 4 months and I just cannot imagine being in an RV with an earthquake.  We are full-timers.  I looked up on my laptop the fault map and read up on it finding out that we were right in the areas of where they were. However, I figure there are so many people there if a big one hits it hits it hits.  You just cannot worry about it, as its like just anything else floods, fires and whatnot.

I've lived in southern California my whole life and have been through many earhquakes. It's quite an experience, you feel completely helpless. All you can do is get under some heavy piece of furniture or a doorway and hope the ground stops shaking.

The house I grew up in had a long hallway. I remember during the Sylmar Quake (the biggest I've experienced) I ran down the hallway bouncing from wall to wall. When I got to the front of the house and looked out our picture window I could see the ground rolling and telephone poles swaying. It was quite a sight. We lived a block away from some large Electric transmission towers and could hear the power lines banging into each other and the towers creaking.

It's amazing how centralized the damage is from the large quakes. Just like tornados. There are certain areas with a lot of damage, maybe a couple of square miles, and then fingers branching out for blocks or miles, with moderate to little damage. And then a few spotty areas with cases of damage, some moderate (usually older masonary buildings), in areas far away from the epicenter.

And just like tornados, the way the media covers the damage, it sounds like all of Los Angeles was destroyed, when in fact the damaged was centered in a couple of mile area about 23 miles east of LA.

Several years ago, we were sleeping in the RV with jacks down when a 4.0 earthquake hit the area and it felt just like a bear was rubbing up against the RV.

If you see the trailer rockin, it's probably due to an earthquake.....or a bear !!!

Red and I were in our 5th wheel in Zion Canyon NP several years ago when a 5.9 earthquake hit. Being from East Texas where we dodge tornadoes and 100 degree temperatures not earthquakes we weren't sure exactly what had happened until one of the neighbors told us the next morning.
The guy next to us was in a tent & sleeping on the ground. He said that even though he was from California and had been through many quakes that one was the most "up close and personal" he had ever experienced.
In my limited opinion I believe an RV with shocks, springs, and rubber on the ground is probably the best place to be to weather that particular phenomenon.
