    • 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 ...
    • Historical and recent large megathrust earthquakes in Chile 
      Ruiz Tapia, Sergio; Madariaga, R. (Elsevier, 2018-05)
      Recent earthquakes in Chile, 2014, Mw 8.2 Iquique, 2015, Mw 8.3 Illapel and 2016, Mw 7.6 Chiloe have put in evidence some problems with the straightforward application of ideas about seismic gaps, earthquake periodicity ...
    • Reawakening of large earthquakes in south central Chile: The 2016 Mw 7.6 Chiloé event 
      Ruiz Tapia, Sergio; Moreno, M.; Melnick, D.; Campo, F. del; Poli, P.; Baez, J. C.; Leyton, F.; Madariaga, R. (American Geophysical Union, 2017)
      On 25 December 2016, the M-w 7.6 Chiloe earthquake broke a plate boundary asperity in south central Chile near the center of the rupture zone of the Mw 9.5 Valdivia earthquake of 1960. To gain insight on decadal-scale ...
    • The deep Peru 2015 doublet earthquakes 
      Ruiz Tapia, Sergio; Tavera, H.; Poli, P.; Herrera C., Carolina; Flores, C.; Rivera, E.; Madariaga, R. (Elsevier, 2017)
      On 24 November 2015 two events of magnitude Mw 7.5 and Mw 7.6 occurred at 600kmdepth under the Peru–Brazil boundary. These two events were separated in time by 300s. Deep event doublets occur often under South America. The ...
