Barbara... more suggestions:the strength and duration of strong ground motion is related to whether you are located on a sedimentary basin, and also to the shallow soils. There exist ground motion maps...you may be able to find them through SCEC pages (www.scec.org). They may be called shake maps, but I'm not sure. They may or may not show the probability that some percentage of "G" (gravity) will be exceeded in the next 30 years. If detailed enough, they might be useful to choosing which parts of Ojai might have the strongest ground motion...although the particular earthquake might give different results. The basin geometry and velocity of the shallow sediments may be particularly important to the motion from the most likely earthquake: one on the somewhat distant San Andreas. Such a quake would cause very strong and long ground motions in Ventura basin in places like Fillmore and Santa Paula (3D ground motion simulations). Ojai is probably not in as deep a basin (would need to look at maps to know if it is a basin at all). A well built 1 or 2 story wood frame house (or engineered house of some other material??) might handle the long-period motions pretty well. It is the taller building that may have problems with such motion. You may want to avoid the edge of a steep hillside...getting your house tossed off of this is not good, nor are landslides.
Qualification: not an expert, but have been exposed to some of this information....you are on your own to confirm or not these things.
