A California earthquake forecast, the 2008 Uniform California Earthquake Rupture Forecast, Version 2 (UCERF 2), has been prepared by the Working Group on California Earthquake Probabilities (WGCEP). Of the hundreds of seismogenic (earthquake causing) geologic faults in California UCERF classifies only six faults as Type A sources, meaning there is sufficient information to both estimate and model the probability of a Magnitude (M) 6.7 or greater earthquake within 30 years. These six faults (summarized in Table A, below) are the: (1) San Andreas (split into northern and southern sections, (2) San Jacinto, (3) Elsinore, (4) Garlock, (5) Calaveras, and (6) Hayward-Rodgers Creek. Faults which are known to be slipping (and therefore seismogenic) but lack sufficient information to fully model how close they might be to rupture are classified as Type B. About twenty of these faults (see Table B) are estimated to have a 5% or greater chance of an M...
