El Mayor-Cucapah Earthquake Rupture Terrestrial Laser Scan-Site 1

This dataset captures primary rupture features along a ~200m long stretch of the 4 April 2010 M 7.2 El Mayor-Cucapah earthquake rupture in northern Baja California, Mexico. This dataset covers in higher resolution sections of the rupture captured by the El Mayor-Cucapah Earthquake (4 April 2010) Rupture Lidar Scan. The scans were collected along the northern Borrego fault over a period of 4 days beginning 16 April 2010, 12 days following the earthquake. This particular dataset covers a section of the rupture across a raised alluvial fan surface where displacements are relatively concentrated along a single fault, with some localized antithetic normal and reverse slip. Depending on how the data is processed and visualized, cm- to m-scale fault scarps, fault free-face striations, displacements defined by offset geomorphic features and cm-scale alluvial fan textures are all visible. Vegetation classification was performed manually in an immersive 3D virtual reality CAVE. This dataset includes intensity-scaled point-coloring. Surveyors: Peter Gold and Austin Elliott, UC Davis
