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 ...
Hidden Holocene Slip Along the Coastal El Yolki Fault in Central Chile and Its Possible Link With Megathrust Earthquakes
(2019)
Megathrust earthquakes are commonly accompanied by increased upper-plate seismicity and occasionally triggered fault slip. In Chile, crustal faults slipped during and after the 2010 Maule (M8.8) earthquake. We studied the ...
Reviewing megathrust slip behavior for recent Mw > 8.0 earthquakes along the Peru-Chilean margin from satellite GOCE gravity field derivatives
(Elsevier Science, 2019-10-20)
The characterization of a seismogenic zone associated with the rupture process that occurs during great megathrust earthquakes has been approached from different perspectives. Different studies lightened the structural ...
Density-depth model of the continental wedge at the maximum slip segment of the Maule Mw8.8 megathrust earthquake
(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 ...
Estimation of slip scenarios for megathrust earthquakes: a case study for Peru
(University of California Santa Barbara, 2011-08-13)
The recent 2011 Tohoku-oki earthquake occurred in a region where giant megathrust earthquakes were not expected. This earthquake proved the difficulty to assess seismic hazard mainly based on information from historical ...
Megathrust Slip Behavior for Great Earthquakes Along the Sumatra-Andaman Subduction Zone Mapped From Satellite GOCE Gravity Field Derivatives
(Frontiers Media, 2021-02)
During the last two decades, space geodesy allowed mapping accurately rupture areas, slip distribution, and seismic coupling by obtaining refined inversion models and greatly improving the study of great megathrust ...
The super-interseismic phase of the megathrust earthquake cycle in Chile
(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 ...
Separating rapid relocking, afterslip, and viscoelastic relaxation: An application of the postseismic straightening method to the Maule 2010 cGPS
(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 ...
An 8 month slow slip event triggers progressive nucleation of the 2014 Chile megathrust
(2017)
The mechanisms leading to large earthquakes are poorly understood and documented. Here we characterize the long-term precursory phase of the 1 April 2014 Mw8.1 North Chile megathrust. We show that a group of coastal GPS ...
Contrasting amount of fluids along the megathrust ruptured by the 2010 Maule earthquake as revealed by a combined analysis of aftershocks and afterslip
(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 ...
