This electronic supplement contains the slip data collected along the Laguna Salada fault during several field campaigns following the April 2010 El Mayor–Cucapah earthquake. In addition to the lateral and vertical displacement measurements, including an estimate of the uncertainty in most cases, the information includes the longitude, latitude, and elevation as determined by handheld Global Positioning Systems, the waypoint number, the soil unit designation following Mueller and Rockwell (1995) if the offset is measured on an alluvial feature, the strike and dip of the fault (if determined), and the type of feature measured.
Table S1. Measurement locations and data for reconstruction of the horizontal and vertical displacement in the 1892 earthquake surface rupture, including the type of feature measured and an estimate of the uncertainty based on clarity of the offset feature.
Download: Image S1 [Google Earth keyhole markup language file; ~853 KB]. KML file of fault scarps recognized along the Laguna Salada fault. Overlays to the base map are located in the two subfolders to the main “paleosrps_lsf” Google Earth file. The subfolder entitled “1892” contains the locations of scarps (shown in red) that appear to have formed or have been reactivated in the 1892 earthquake, and the subfolder entitled “pre1892/unclassified” contains the scarps (shown in black) that either did not break in the 1892 earthquake or we couldn’t tell if they did or didn’t (i.e., evidence of recent scarp reactivation was lacking). The subfolders may be opened and closed using the check boxes beside their names in the Temporary Places menu.
