The North American Cordillera extends from southern Mexico to northern Alaska and includes several active fault systems. Strike-slip faults are a major feature in the neotectonic framework of the North American Cordillera and, in many places, coincide with profound geophysical boundaries in the lithosphere. Syntheses of regional geological and geophysical datasets reveal that the crustal-scale architecture of the faults is tied to their geologic evolution, but a number of questions remain regarding the long-term evolution of these structures, leading to the present-day crustal structure and seismogenic behavior. This session seeks to highlight present research relating the long-term geological evolution of Cordilleran strike-slip faults as it relates to the neotectonic, seismological and geophysical signature of the faults.
