My grandparents survived the April 18, 1906 San Francisco Earthquake and Fire, so I always consider Earthquake Awareness Month as a personal issue.

This ad that I wrote pro bono for the American Red Cross of the Bay Area many years ago provides information about how to create a family survival plan when, not if, the next big one strikes. It only takes a few minutes to formulate a plan so I urge you to talk about it now.

By the way, based on research conducted since the 1989 Loma Prieta earthquake, U.S. Geological Survey (USGS) and other scientists conclude that there is a 62% probability of at least one magnitude 6.7 or greater quake, capable of causing widespread damage, striking the San Francisco Bay region before 2032. Read more from USGS.

Plus, there are seven faults crisscrossing the Bay Area, not just the San Andreas, which caused the 1906 quake.

How much of a food and water supply should you stockpile in case of an emergency like a major quake that can cut your electricity? Experts say three to seven days, depending on your comfort factor.
