    • A study of the 2015 Mw 8.3 Illapel earthquake and tsunami: numerical and analytical approaches 
      Fuentes, Mauricio; Riquelme, Sebastián; Hayes, Gavin; Medina, Miguel; Melgar, Diego; Vargas, Gabriel; González, José; Villalobos, Angelo (Springer, 2016)
      The September 16, 2015 Illapel, Chile earthquake triggered a large tsunami, causing both economic losses and fatalities. To study the coastal effects of this earthquake, and to understand how such hazards might be accurately ...
    • Focal mechanism, magnitude, and finite-fault rapid estimation using the elliptical patch method in Chile 
      Leyton, F.; Ruiz Tapia, Sergio; Madariaga, R. (Seismological Soc Amer, 2018)
      Nowadays, most fast, automatic algorithms estimate the magnitude and location of earthquakes assuming a point-source approximation that might produce large errors in the predicted shaking. In this study, using a kinematic ...
    • Geophysical characterization of the chilean seismological stations: first results 
      Leyton, F.; Leopold, A.; Hurtado, G.; Pastén, C.; Ruiz Tapia, Sergio; Montalva, G.; Saéz, E. (Seismological Soc Amer, 2018)
      The Chilean Seismological Network has been rapidly growing in recent years, going from a few dozens stations working before 2010 to nearly a 100 installed all over the territory. Even more, nearly 300 strong-motion stations ...
    • Large slip, long duration, and moderate shaking of the Nicaragua 1992 tsunami earthquake caused by low ... 
      Sallarès, Valentí; Prada, Manel; Riquelme Muñiz, Sebastián; Meléndez, Adrià; Calahorrano, Alcinoe; Grevemeyer, Ingo; Ranero, César R. (American Association Advancement Science, 2021)
      Large earthquake ruptures propagating up to areas close to subduction trenches are infrequent, but when they occur, they heavily displace the ocean seafloor originating destructive tsunamis. The current paradigm is that ...
    • Seismic hazard in low slip rate crustal faults, estimating the characteristic event and the most hazardous ... 
      Pérez Estay, Nicolás; Yáñez Carrizo, Gonzalo; Carretier, Sebastien; Lira, Elías; Maringue, José (Copernicus Gesellschaft, 2016)
      Crustal faults located close to cities may induce catastrophic damages. When recurrence times are in the range of 1000-10000 or higher, actions to mitigate the effects of the associated earthquake are hampered by the lack ...
    • Subduction zone fluids and arc magmas conducted by lithospheric deformed regions beneath the central Andes 
      Contreras Reyes, Eduardo Eliseo; Díaz, D.; Bello González, Juan Pablo; Slezak, Katarzyna Anna; Potin, Bertrand Jean-Maurice; Comte Selman, Diana Patricia; Maksymowicz Silva, Ana Maria; Ruiz, J. A.; Osses Alvarado, Axel Esteban; Ruiz, S. (Nature, 2021)
      Dehydration of the oceanic subducting slab promotes the formation of magmatic arcs, intra-slab intermediate-depth seismicity, and hydration of the overlying mantle wedge. However, the complex permeability structure of the ...
    • The seismic network of Chile 
      Barrientos, Sergio (Seismological Society of America, 2018)
      Chile is frequently affected by large and potentially tsunamigenic and damaging earthquakes as a result of rapid convergence of the Nazca plate beneath the South America plate. Ten M 8 or larger earthquakes have occurred ...
