    • Liquiñe‑Ofqui’s fast slipping intra‑volcanic arc crustal faulting above the subducted Chile Ridge 
      De Pascale, Gregory P.; Froude, Melanie; Penna, Ivanna; Hermanns, Reginald L; Sepúlveda, Sergio A.; Moncada, Daniel; Pérsico, Mario; Easton Vargas, Gabriel; Villalobos, Angelo; Gutiérrez, Francisco (Nature Research, 2021)
      The southernmost portion of the Liquiñe-Ofqui fault zone (LOFZ) lies within the proposed slab window which formed due to oblique subduction of the Chile Ridge in Patagonia. Mapping of paleo-surface ruptures, offsets, and ...
    • Months-long thousand-kilometre-scale wobbling before great subduction earthquakes 
      Bedford, Jonathan R.; Moreno, Marcos; Deng, Zhiguo; Oncken, Onno; Schurr, Bernd; John, Timm; Báez, Juan Carlos; Bevis, Michael (Nature, 2020)
      Megathrust earthquakes are responsible for some of the most devastating natural disasters(1). To better understand the physical mechanisms of earthquake generation, subduction zones worldwide are continuously monitored ...
    • La Palma island (Spain) geothermal system revealed by 3D magnetotelluric data inversión 
      Di Paolo, Federico; Ledo, Juanjo; Slezak, Katarzyna; Martínez van Dorth, David; Cabrera Pérez, Iván; Pérez, Nemesio M. (Nature, 2020)
      The study of geothermal systems is nowadays a topic of great importance because of the huge amount of energy that could be converted in electricity for human consumption from such sources. Among the various geophysical ...
    • Physical characterization of fault rocks within the Opalinus Clay formation 
      Orellana Espinoza, Luis Felipe; Nussbaum, Christophe; Grafulha, Luiz; Henry, Pierre; Violay, Marie (Nature, 2022)
      Near-surface disposal of radioactive waste in shales is a promising option to safeguard the population and environment. However, natural faults intersecting these geological formations can potentially affect the long-term ...
    • Seismicity in a Transpressional Volcanic Arc: The Liquine-Ofqui Fault System in the Puyuhuapi Area, Southern ... 
      Pérez Estay, Nicolás; Yáñez, Gonzalo; Crempien, Jorge; Roquer, Tomás; Cembrano, José; Valdenegro, Pablo; Aravena, Diego; Arancibia, Gloria; Morata Céspedes, Diego (Amer Geophysical Union, 2020)
      Understanding the relationship between crustal faults and volcanic activity in transpressional environments is a main goal in geosciences and could help to understand geothermal resources and evaluate geological hazards. ...
    • The role of interplate locking on the seismic reactivation of upper plate faults on the subduction margin ... 
      González, Gabriel; Pasten Araya, Francisco; Víctor, Pía; González, Yerko; Valenzuela, Jordan; Shrivastava, Mahesh (Nature, 2021)
      Quaternary deformation in the northern Chile forearc is controlled by trench parallel shortening along reactivated Mesozoic faults. Dextral strikes-slip is expressed in NW-SE striking faults of the Atacama Fault System, ...
