Project Abstract |
This workshop explored the San Gorgonio Pass "knot" region as a candidate for a SCEC Special Fault Study Area and outlined a plan to fill existing knowledge gaps. Specific topics included the geometry of active subsurface faulting, the potential for earthquakes on the complex fault system in this region, and the likelihood of a ‘super-earthquake’ that would propagate along the San Andreas system through the pass, leading to a very large-magnitude and damaging event. The workshop brought together geoscientists from a wide spectrum of interests including tectonic geomorphology, structural geology, mechanical modeling, rupture modeling, gravity and magnetic modeling, seismology, geochronology, geodesy, and fault and rock mechanics. The first day was a blend of short science talks on case studies with discussions of specific topics. On the second day, we took a field trip to view key sites in San Gorgonio Pass. |
Intellectual Merit | Knowledge gaps for the San Gorgonio pass were identified at the workshop. We outlined a science plan that could address major issues within the pass within 4 years. |
Broader Impacts | The science plan incorporates every discipline within the SCEC community and a vast range of expertise. If the San Gorgonio Pass is established as a special study area, many PIs and students will be supported to work in this area. |
