    • Aftershock seismicity and tectonic setting of the 2015 September 16 Mw 8.3 Illapel earthquake, Central Chile 
      Lange, Dietrich; Geersen, Jacob; Barrientos Parra, Sergio; Moreno, Marcos; Grevemeyer, Ingo; Contreras Reyes, Eduardo; Kopp, Heidrun (Oxford University Press, 2016)
      Powerful subduction zone earthquakes rupture thousands of square kilometres along continental margins but at certain locations earthquake rupture terminates. To date, detailed knowledge of the parameters that govern seismic ...
    • Back to full interseismic plate locking decades after the giant 1960 Chile earthquake 
      Melnick, Daniel; Li, Shaoyang; Moreno, Marcos; Cisternas, Marco; Jara-Muñoz, Julius; Wesson, Robert; Nelson, Alan; Báez, Juan Carlos; Deng, Zhiguo (Nature Publishing Group, 2018)
      © 2018, The Author(s). Great megathrust earthquakes arise from the sudden release of energy accumulated during centuries of interseismic plate convergence. The moment deficit (energy available for future earthquakes) is ...
    • 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 ...
    • Contrasting amount of fluids along the megathrust ruptured by the 2010 Maule earthquake as revealed by a ... 
      Tassara, Andrés; Soto, Hugo; Bedford, Jonathan; Moreno, Marcos; Baez Soto, Juan Carlos (Elsevier, 2016-03)
      We present a novel approach combining time-variable computations of b-value and afterslip to study the postseismic activity following the Mw 8.8 Maule 2010 earthquake. We subdivided the first 392 days after the mainshock ...
    • Coseismic slip and afterslip of the 2015Mw 8.3 Illapel (Chile) earthquake determined from continuous GPS data 
      Shrivastava, Mahesh; González, Gabriel; Moreno, Marcos; Chlieh, Mohamed; Salazar, Pablo; Reddy, C. D.; Báez, Juan Carlos; Yáñez, Gonzalo; González, Juan; de la Llera, Juan Carlos (American Geophysical Union, 2016)
      We analyzed the coseismic and early postseismic deformation of the 2015, M-w 8.3 Illapel earthquake by inverting 13 continuous GPS time series. The seismic rupture concentrated in a shallow (<20km depth) and 100km long ...
    • Earthquake segmentation in northern Chile correlates with curved plate geometry 
      Shrivastava, Mahesh N.; González, Gabriel; Moreno, Marcos; Soto, Hugo; Schurr, Bernd; Salazar, Pablo; Báez, Juan Carlos (Nature Publishing Group, 2019)
      We performed an integrated analysis of the coseismic slip, afterslip and aftershock activity of the 2014 M w 8.1 Pisagua earthquake. This earthquake seems to be spatially located between two major historical earthquakes, ...
    • 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 ...
    • Separating rapid relocking, afterslip, and viscoelastic relaxation: An application of the postseismic ... 
      Bedford, Jonathan; Moreno, Marcos; Li, Shaoyang; Oncken, Onno; Báez, Juan Carlos; Bevis, Michael; Heidbach, Oliver; Lange, Dietrich (American Geophysical Union, 2016)
      The postseismic deformation captured with continuous Global Positioning System (cGPS) monitoring following many recent megathrust events has been shown to be a signal composed of two dominant processes: afterslip on the ...
    • The super-interseismic phase of the megathrust earthquake cycle in Chile 
      Melnick, Daniel; Moreno, Marcos; Quinteros, Javier; Báez, Juan Carlos; Deng, Zhiguo; Li, Shaoyang; Oncken, Onno (Blackwell, 2017)
      Along a subduction zone, great megathrust earthquakes recur either after long seismic gaps lastingseveral decades to centuries or over much shorter periods lasting hours to a few years when cascadingsuccessions of earthquakes ...
