    • A three step recipe for designing auxetic materials on demand 
      Acuña, Daniel; Gutiérrez Figueroa, Francisco Javier; Silva F., Rodrigo; Palza Cordero, Humberto; Núñez Vásquez, Alvaro; Düring, Gustavo (Nature, 2022)
      Auxetics are an unusual family of materials that, for instance, when stretched in a particular direction will exhibit an expansion of the dimensions that are perpendicular to the applied stress; however, despite many known ...
    • Active faulting, submarine surface rupture, and seismic migration along the liquine-ofqui fault system, ... 
      Villalobos, Angelo; Easton, Gabriel; Maksymowicz, Andrei; Ruiz, Sergio; Lastras, Galderic; De Pascale, Gregory P.; Agurto Detzel, Hans (Amer Geophysical Union, 2020)
      The intra-arc Liquine-Ofqui Fault System (LOFS) is an active transpressive fault zone located in the Patagonian Andes of Chile. In 2007, a seismic sequence occurred in the Aysen Fjord region of Chilean Patagonia along the ...
    • Episodic construction of the early Andean Cordillera unravelled by zircon petrochronology 
      Jara, José Joaquín; Barra Pantoja, Luis Fernando; Reich Morales, Martín Herbert; Leisen, Mathieu; Romero, Rurik; Morata Céspedes, Diego Antonio (Nature Research, 2021)
      The subduction of oceanic plates beneath continental lithosphere is responsible for continental growth and recycling of oceanic crust, promoting the formation of Cordilleran arcs. However, the processes that control the ...
    • Estimating tunnel wall displacements using a simple sensor based on a Brillouin optical time domain ... 
      Moffat Covarrubias, Ricardo; Sotomayor, Javier; Beltrán Morales, Juan Felipe (Elsevier, 2015)
      A strain monitoring system based on a PVC tube instrumented with optical fiber connected to a Brillouin Optical Time Domain Reflectometer (BOTDR) apparatus is proposed to monitor rock mass movement in an underground mine. ...
    • G-FAST earthquake early warning potential for great earthquakes in Chile 
      Crowell, Brendan W.; Schmidt, David A.; Bodin, Paul; Vidale, John E.; Baker, Ben; Barrientos, Sergio; Geng, Jianghui (Seismological Soc Amer, 2018)
      The importance of Global Navigation Satellite System (GNSS)-based earthquake early warning for modeling large earthquakes has been studied extensively over the past decade, and several such systems are currently under ...
    • Present-day geodynamics of the western alps: new insights from earthquake mechanisms 
      Mathey, Marguerite; Sue, Christian; Pagani, Colin; Baize, Stéphane; Walpersdorf, Andrea; Bodin, Thomas; Husson, Laurent; Hannouz, Estelle; Potin, Bertrand Jean-Maurice (Copernicus Gesellschaft MBH, 2021)
      Due to the low to moderate seismicity of the European Western Alps, few focal mechanisms are available in this region to this day, and the corresponding current seismic stress and strain fields remain partly elusive. The ...
    • Regional electrical structure of the Andean subduction zone in central Chile (35 degrees 36 degrees S) using ... 
      Reyes Wagner, Valentina Fernanda; Díaz Alvarado, Daniel; Cordell, Darcy; Unsworth, Martyn (Springer, 2017)
      A profile of broadband magnetotelluric stations was acquired between 2009 and 2016 at 35 degrees-36 degrees S in the Southern Volcanic Zone of the Chilean Andes to image the subduction zone and its relation with the volcanic ...
    • 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. ...
    • Syn-deformational anatexis along the Santa Rosa river section, Argentina: Feedback relations between ... 
      Tibaldi, Alina M.; Barzola, Matías G.; Cristofolini, Eber A.; Otamendi, Juan E.; Demichelis, Alejandro H.; Leisen, Mathieu; Romero, Rurik; Barra, Fernando; Camilletti, Giuliano; Armas, Paula (Elsevier Ltd, 2019)
      Mass transference from lower to upper crustal levels requires an efficient network of pathways that act as channels for draining melts from the source and transferring magmas through the crust. We report on a mid-crustal ...
    • The 21 May 1960 M-w 8.1 Concepción Earthquake: A Deep Megathrust Foreshock That Started the 1960 Central-South ... 
      Ojeda Vargas, Javier; Ruiz Tapia, Sergio; Campo, Francisco del; Carvajal, Matías (Seismological Society of America, 2020)
      One of the most notable seismic sequences in modern times was recorded in May 1960 along the southern Chilean subduction zone. The sequence started on 21 May with the M-w 8.1 Concepcion earthquake; 33 hr later the M-w 9.5 ...
    • 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, ...
    • W phase source inversion using high-rate regional GPS data for large earthquakes 
      Riquelme, S.; Bravo, F.; Melgar, D.; Benavente, R.; Geng, J.; Barrientos, S.; Campos Muñoz, Jaime (Amer Geophysical Union, 2016)
      W phase moment tensor inversion has proven to be a reliable method for rapid characterization of large earthquakes. For global purposes it is used at the United States Geological Survey, Pacific Tsunami Warning Center, and ...
