Situation map of northern Chile–southern Peru. The terminations of the 1995 Antofagasta (Mw 8.0) and 2001 Arequipa (Mw 8.4) interplate earthquake ruptures are indicated, as well as the 2005 Tarapaca (Mw 7.8) intermediate-depth earthquakes rupture zone (hatched surfaces labeled 1995, 2001, and 2005, respectively, Ruegg et al., 1996; Delouis et al., 1997; Pritchard et al., 2006; Bilek and Ruff, 2002; Delouis and Legrand, 2007). The gray contoured areas in the rectangular frame correspond to the surface projection of the slip model obtained in this study for the 2007 Tocopilla earthquake. The double dashed line AB indicates the cross-section line of (b). Also displayed, the focal mechanism here determined for the Tocopilla mainshock, in black, and the focal mechanisms of the 1995, 2001, and 2006 events, in gray (Delouis et al., 1997; Bilek and Ruff, 2002; Delouis and Legrand, 2007). Black diamonds are the six strong-motion stations that recorded the 2007 mainshock diamonds: Iquique (IQUI), Pica (PICA), Tocopilla (TOCO), Calama (CALA), Mejillones (MEJI), and Antofagasta (ANTO). Dashed line: G1, seismic gap before the 2007 rupture and remaining gap for the occurrence of a very large (M&gt;8.5) event; G2, reduced gap, most likely place for the next large (M&gt;7.5) underthrusting event. (b) Cross section showing background seismicity from 1991 to 1994 well recorded by a local network between latitude 24.5° S and 22.5° S. Same longitude scale as in (a). The black line indicates the main slip zone during the 2007 Tocopilla event. The dashed line corresponds to the shallower part of the slip distribution in the southern part of the rupture (same horizontal and vertical scale).
