Chilean megathrust earthquake recurrence linked to frictional contrast at depth
(2018)
Fundamental processes of the seismic cycle in subduction zones, including those controlling the recurrence and size of great earthquakes, are still poorly understood. Here, by studying the 2016 earthquake in southern ...
Coseismic slip and early afterslip of the 2015 Illapel, Chile, earthquake: Implications for frictional heterogeneity and coastal uplift
(American Geophysical Union, 2016)
Great subduction earthquakes are thought to rupture portions of the megathrust, where interseismic coupling is high and velocity-weakening frictional behavior is dominant, releasing elastic deformation accrued over a seismic ...
Nonlinear FE model updating of seismic isolated bridge instrumented during the 2010 Mw 8.8 Maule-Chile Earthquake
(Elsevier, 2017)
In this paper, nonlinear finite element model updating (FEMU) is performed to study the prediction accuracy of a state-of-the-art
finite element (FE) model of a seismic isolated bridge (SIB). The seismic isolator model ...
Seismic and aseismic slip on the Central Peru megathrust
(Nature Research, 2010-05-06)
Slip on a subduction megathrust can be seismic or aseismic, with the two modes of slip complementing each other in time and space to accommodate the long-term plate motions. Although slip is almost purely aseismic at depths ...
The first since 1960: a large event in the Valdivia segment of the Chilean subduction zone, the 2016 M7.6 Melinka earthquake
(Elsevier, 2017)
We present results for joint kinematic inversion of high-rate GPS, strong motion and InSAR data for the 2016 M7.6 Melinka earthquake. We show that the source is a compact 35 s long rupture with 5.0 +/- 0.15 m of peak slip. ...
Goce derived geoid changes before the Pisagua 2014 earthquake
(Elsevier, 2018-01)
The analysis of space – time surface deformation during earthquakes reveals the variable state of stress that occurs at deep crustal levels, and this information can be used to better understand the seismic cycle. Understanding ...
Characterization of historical megathrust earthquake ruptures in South Central Chile using logic tree analysis.
(Universidad de Concepción.Facultad de Ciencias Físicas y Matemáticas, 2023)
Characterizing the spatial distribution of ruptures from historical and recent earthquakes is key to understanding the seismic cycle of large earthquakes in subduction zones, and thus to assessing the potential risks ...
Coseismic seafloor deformation in the trench region during the Mw8.8 Maule megathrust earthquake
(Nature, 2017)
The Mw 8.8 megathrust earthquake that occurred on 27 February 2010 offshore the Maule region of
central Chile triggered a destructive tsunami. Whether the earthquake rupture extended to the shallow
part of the plate ...
