Paleoseismicity of the San Gorgonio Pass fault zone at Millard Canyon: Testing the likelihood of a through-going San Andreas rupture

The San Gorgonio Pass fault zone is a thrust-dominated, complex fault system, that connects strike-slip segments of the southern San Andreas fault. The structural complexities of the Pass region are considered by some to be a barrier to through-going San Andreas fault ruptures. Understanding the rupture history of this region is key to forecasting large earthquakes along the southern San Andreas fault. (See more in text.)
