(a) Map showing the tectonic boundaries in the Scotia arc region. The red line indicates the current tectonic plate boundaries. (b) Map of the study area. The red line represents the Magallanes–Fagnano fault system/South America–Scotia plate boundary. The dark blue line indicates the deformational front of the Austral–Malvinas fold–thrust belt. The focal mechanism is from Forsyth (1975) and Pelayo and Wiens (1989). The yellow polygons indicate the location of the strike-slip basins.
