Ruiz Tapia, Sergio; Grandin, Raphael; Dionicio, Viviana; Satriano, Claudio; Fuenzalida, Amaya; Vigny, Christophe; Kiraly, Eszter; Meyer, Clio; Baez, Juan Carlos; Riquelme, Sebastián; Madariaga, Raúl; Campos Muñoz, Jaime (Elsevier, 2013)The Mw 7.0 Constitución earthquake of March 2012 is one of the largest interplate aftershocks of the Maule 2010 Mw 8.8 mega-thrust earthquake. This event was recorded by high-rate GPS stations, local seismometers and ...

Maksymowicz Jeria, Andrei; Tréhu, Anne M.; Contreras Reyes, Eduardo; Ruiz Tapia, Sergio (Elsevier, 2015)Complexities in the rupture process during a megathrust earthquake can be attributed to the combined effect of inhomogeneous distribution of stress accumulated during the interseismic period and inho-mogeneous rheology of ...

Ruiz Tapia, Sergio; Madariaga, Raúl (AMER GEOPHYSICAL UNION, 2011-05-14)We perform a full dynamic inversion at low frequencies of the 16 December 2007 (Mw = 6.7) northern Chile earthquake that we model as a simple elliptical patch. We use two different stress-friction end-member models: ...

Poli, Piero; Prieto, German; Rivera, Efrain; Ruiz Tapia, Sergio (AMER GEOPHYSICAL UNION, 2016)Intermediate depth earthquakes often occur along subducting lithosphere, but despite their ubiquity the physical mechanism responsible for promoting brittle or brittle-like failure is not well constrained. Large concentrations ...

Ruiz Tapia, Sergio; Kausel Vecchiola, Edgar; Campos Muñoz, Jaime; Saragoni, G. R.; Madariaga, R. (2011)The Chilean subduction zone is one of the most active of the world with M = 8 or larger interplate thrust earthquakes occurring every 10 years or so on the average. The identification and characterization of pulses ...

Ruiz Tapia, Sergio; Metois, M.; Fuenzalida, A.; Ruiz Paredes, Javier; Grandin, R.; Vigny, C.; Madariaga, R.; Campos Muñoz, Jaime (American Association for the Advancement of Science, 2014)The subduction zone in northern Chile is a well-identified seismic gap that last ruptured in 1877. The moment magnitude (Mw) 8.1 Iquique earthquake of 1 April 2014 broke a highly coupled portion of this gap. To understand ...

Lancieri, M.; Fuenzalida, A.; Ruiz Tapia, Sergio; Madariaga, R. (2011-04)We studied the correlation between the final event magnitude and four parameters obtained from the early portion of P and S phases for a set of high quality subduction events. These relationships are used in the framework ...

Leyton, F.; Ruiz Tapia, Sergio; Sepúlveda Valenzuela, Sergio; Contreras, J. P.; Rebolledo Lemus, Sofía; Astroza Inostroza, Maximiliano (Elsevier, 2013)Nowadays, microtremors' horizontal-to-vertical spectral ratio (HVSR) has been extensively used in the estimation of the predominant vibration frequency of soils, mainly for microzonation purposes. In the present study, ...
