Figure 1

(a) Seismotectonic map of the study region. The blue and black beachballs indicate the GCMT solutions10,11 for the mainshock and 3-day aftershocks, respectively. The A–A′ line corresponds to the top of the model plane used for our optimum finite-fault solution. The star shows the epicentre of the 2010 El Mayor-Cucapah earthquake. Red lines indicate the plate-boundary fault16 and the Laguna Salada fault (LSF)–Cañada David detachment (CDD) fault system17. The inset shows the regional tectonic setting, and the dashed rectangle shows the area shown in (b). (b) Seismotectonic map of the area along A–A′. Blue dots represent surface faults12. Blue-shading highlights the Paso Inferior and Puerta accommodation zones12. The star is the relocated epicentre13. Black dots show relocated 3-day aftershocks13. The dotted line shows the U.S.–Mexico border. This figure was made with Generic Mapping Tools (v6.2.0)18 and the background topography in (a) is based on SRTMGL3 data19.
