This map displays earthquake probabilities for several faults in the San Francisco Bay Area. The probability values are for the occurrence of one or more major (magnitude greater than or equal to 6.7) earthquakes in the San Francisco Bay Region during the next thirty years. Each fault on the map is color-coded to indicate the relative probability, and numerical values are displayed in boxes. The site includes links to a fact sheet and full technical report that summarize the findings, indicating a 62 percent total probability of a major earthquake over the next thirty years. There are also links to planning scenario maps, a study on potential losses, a webcast on earthquake probability, and to a set of downloadable graphics (TIF or PDF files) used in the probability study.
