El Mayor-Cucapah Earthquake Rupture Terrestrial Laser Scan-Site 2

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 <a href=/gridsphere/gridsphere?gs_action='lidarDataset&cid=geonlidarframeportlet&opentopoID=OTLAS.122010.32611.1'>El Mayor-Cucapah Earthquake (4 April 2010) Rupture Lidar Scan</a>. The scans were collected along the northern Borrego fault in a single day (20 April 2010) 16 days following the earthquake. This particular dataset covers a section of the rupture along a bedrock rangefront where displacements are highly concentrated along a single fault, with some localized antithetic normal 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, and a paleo-fault scarp 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

本数据集记录了墨西哥下加利福尼亚州北部于2010年4月4日发生的M 7.2级El Mayor-Cucapah地震沿约200米长的破裂特征。该数据集覆盖了由<a href=/gridsphere/gridsphere?gs_action='lidarDataset&cid=geonlidarframeportlet&opentopoID=OTLAS.122010.32611.1'>El Mayor-Cucapah地震（2010年4月4日）破裂激光扫描</a>获取的破裂的高分辨率区域。这些扫描在地震发生后第16天，即2010年4月20日，沿北部Borrego断层进行，耗时一日。特定数据集覆盖了沿基岩前沿的破裂区域，其中位移在单一断层上高度集中，并伴有局部反方向的正常滑移。根据数据处理和可视化的不同，厘米至米级的断层疤痕、无断层面条纹、由错位地貌特征定义的位移以及厘米级的冲积扇纹理，以及古断层疤痕均清晰可见。植被分类是在沉浸式3D虚拟现实CAVE中进行的手动操作。该数据集包含强度分级的点彩绘。测量人员：彼得·戈尔德和奥斯汀·埃利奥特，加州大学戴维斯分校。
