    • An 8month slow slip event triggers progressive nucleation of the 2014 Chile megathrust 
      Socquet, Anne; Piña Valdés, Jesús; Jara, Jorge; Cotton, Fabrice; Walpersdorf, Andrea; Cotte, Nathalie; Specht, Sebastián; Ortega Culaciati, Francisco; Carrizo, Daniel; Norabuena, Edmundo (American Geophysical Union, 2017-05-16)
      The mechanisms leading to large earthquakes are poorly understood and documented. Here we characterize the long-term precursory phase of the 1 April 2014 M(w)8.1 North Chile megathrust. We show that a group of coastal GPS ...
    • Characterizing Afterslip and ground displacement rate increase following the 2014 Iquique-Pisagua mw 8.1 ... 
      Hoffmann, Felix; Metzger, Sabrina; Moreno, Marcos; Deng, Zhiguo; Sippl, Christian; Ortega Culaciati, Francisco; Oncken, Onno (Amer Geophysical Union, 2018-05)
      The 2014 Iquique-Pisagua M-w 8.1 earthquake ruptured only parts of the 1877 Northern Chile-Southern Peru seismic gap. Here we present a comprehensive analysis of 152 continuous and campaign Global Positioning System time ...
    • Post-seismic response of the outer accretionary prism after the 2010 Maule earthquake, Chile 
      Trehu, Anne M.; de Moor, Alexander; Mieres Madrid, José; Sáez, Miguel; Chadwell, C. David; Ortega Culaciati, Francisco; Ruiz, Javier; Ruiz, Sergio; Tryon, Michael D. (The Geological Society of America, 2020)
      To investigate the dynamic response of the outer accretionary prism up-dip from the patch of greatest slip during the 2010 M-w 8.8 Maule earthquake (Chile), 10 ocean-bottom seismometers (OBSs) were deployed from May 2012 ...
    • Three-dimensional elastic wave speeds in the northern Chile subduction zone: variations in hydration in the ... 
      Comte Selman, Diana; Carrizo, Daniel; Roecker, Steven; Ortega Culaciati, Francisco; Peyrat, Sophie (Oxford University Press, 2016)
      We use seismic tomography to investigate the state of the supraslab mantle beneath northern Chile, a part of the Nazca-South America Plate boundary known for frequent megathrust earthquakes and active volcanism. We performed ...
