3D perspective view of California (outlined in white) and buffer zone showing the 2,606 fault sections of UCERF 3.1, with white boxes showing the San Francisco Bay (SF) and Los Angeles (LA) areas. Colors show the estimated probability of a section participating in one or more M ≥ 6.7 earthquakes in the 30 years following 2014, accounting for the current level of stress accumulated since the last earthquake. This version's scale uses percentages.
