(A) Local setting and geology (1:1,000,000; SERNAGEOMIN, 2003) of the southernmost LOFZ, note the mapped main trace of the LOFZ, the correlation with volcanoes and LOFZ, and the location of the Volcan Mate Grande (VMG) and caldera that were discovered during this investigation. Note Hudson is the Quaternary Volcanics to the Southeast of the VMG. Note that the majority of the CM area was part of the 1960 Valdivia Mw 9.5 Giant earthquake rupture zone. (B) Long-term Miocene to present LOFZ indicators (the opening of the Golfo de Penas (~ 100 km) and the ~ 65 km geologic separation of the Miocene Patagonian Batholith (Mg). (C) Inset showing (Mg) that is located east of the LOFZ and used as a piercing point. (D) Retrodeformed model back-slipped by 65 km along the LOFZ to reconnect the unit Mg. Base hillshade was generated with Esri ArcMap v.10.3 software (under fair terms of use, https://www.esri.com/en-us/legal/copyright-trademarks)39 using a digital elevation model downloaded from ALOS PALSAR Global Radar Imagery40 with 12.5 m resolution (https://asf.alaska.edu/data-sets/sar-data-sets/alos-palsar/).
