“…In this case, the nature of the landslide and the low temporal resolution of the RADARSAT-2 interferometric stack influenced the capability of satellite InSAR to monitor the landslide's evolution towards the failure. However, satellite InSAR provided unique evidence regarding the unstable mass extension and the characterization of the failure mechanism [68]. The high PM density enabled spatial constraint of the landslide area, providing important details that could have been useful for the determination of failure size, extent and runout distance analysis, to be used by decision makers in the emergency response plan implemented before the catastrophic collapse [70].…”

“…The Bingham landslide occurred 10 April 2013 (Salt Lake City, UT, USA) in the Bingham Canyon Mine, one of the world's largest copper deposits [67,68] (Figure 7a). It was characterized by a complex failure mechanism evolved in the porphyry copper system, mainly composed by Permian and Pennsylvanian sedimentary units rich in copper, gold, silver, molybdenum, lead and zinc [67].…”

“…Estimates based on seismic surface wave magnitudes placed the volume of the first event (Event 1) at approximately from 1.5 to 2 times the volume of the second event (Event 2) (Moore et al., 2017). The basal failure surface was defined by a persistent, gently east dipping fault in the source zone (Moore et al., 2017; Williams et al., 2021). After vacating the source area, material from both events made an approximately 90° bend to the south before descending down the steeper inner pit walls.…”

“…Mientras que el empleo de radares de apertura sintética terrestres (ground-based synthetic aperture radars, GB-SARs) ha demostrado ser una técnica operativa y eficaz para la monitorización de taludes en minas a cielo abierto (Monserrat et al, 2014), el uso del InSAR satélite para este fin es poco común, dada la decorrelación producida por las fuertes variaciones topográficas habitualmente asociadas a las operaciones mineras a cielo abierto. Concretamente, la monitorización de taludes mineros mediante InSAR satélite se ha documentado en algunas explotaciones mineras de Australia (Carlà et al, 2019;Thomas et al, 2019), Brasil (Paradella et al, 2015;Holden et al, 2020), España (Herrera et al, 2010;López-Vinielles et al, 2020, 2021a, Sudáfrica (Woo et al, 2012), Turquía (Carlà et al, 2018) y Estados Unidos (Styles et al, 2011;Williams et al, 2019), englobando tanto análisis predictivos (pre-evento) de inestabilidades de talud como análisis retrospectivos (post-evento) de roturas de talud.…”
