Resources for Strengthening Your Home to Resist Earthquakes, and Earthquake Preparedness
International Code Council (ICC) PublicationsThe International Existing Building Code (IEBC). The IEBC may be available for free viewing on the web somewhere, but it is not easy to find. The IEBC is almost identical to the California Existing Building Code which is available for free viewing (see below under "Standard Plans").

“Wood-Framed Shear Wall Construction—an Illustrated Guide” (SECOND EDITION)
The second edition of the Shear Wall Construction Guide is 180 pages long, with over 150 illustrations and photos. Chapter 6 introduces residential earthquake retrofits.
The Shear Wall Construction Guide addresses many field conditions and obstacles encountered in shear wall construction. It also includes information on collectors, openings through shear walls, wood shrinkage, and other topics related to new or retrofit construction.
Both of the above publications are also available from Builders Booksource in Berkeley: 1817 4th St., Berkeley, CA 94710 (510) 845-6874
US Federal Emergency Management Agency (FEMA) documentsFEMA P-593 Seismic Rehabilitation Training for One- and Two-Family Wood-Frame Dwellings--2008
Features a very useful color-coded chart showing common hazards to look for; chart gives references of where to find more info (many of which are listed here). Current format is essentially Power Point slides; this is a good review if you attended the seminar, but without accompanying discussion it is unlikely a reader will learn retrofit methods by reading the materials alone. Contains good examples of some common mis-applications of hardware to avoid.
FEMA P-547 Techniques for the Seismic Rehabilitation of Existing Buildings--2006
FEMA P 50-1 "Seismic rehabilitation guidelines for detached, single-family wood-framed buildings" (Chapter 2 only).
"Standard" Earthquake Retrofit Plans
Note: All of the "standard" plans have limited applicability
The Association of Bay Area Governments' Standard Plan A (commonly called "Plan Set A") has the following limitations:
The following “standard plans” are either identical to, or minor variations on, information presented in the International Existing Building Code (IEBC). The IEBC is based on early recommendations from FEMA.
US Geological Survey publicationsVarious regional guides published jointly with local agencies. Overview of seismology, shaking maps, fault locations, emergency preparations. Customized for several regions.
As of November, 2012, they all show the wrong direction to turn a gas supply valve to close it (although many gas shut-off valves can be turned either way, some cannot; check yours before the quake).
Note: Print these out or become familiar with them BEFORE the power goes off in a disaster.

"Surviving in Earthquake Country"—by Peter Yanev, Structural EngineerNew edition released in 2010 or so. Excellent overview of geologic considerations, behavior of various high-rise and commercial building types, and residential hazards (such as hillside homes) to look for.
