Slip distribution of the 2014 M-w=8.1 Pisagua, northern Chile, earthquake sequence estimated from coseismic fore-arc surface cracks
(2016)
The 2014 Mw = 8.1 Iquique (Pisagua), Chile, earthquake sequence ruptured a segment of the Nazca‐South America subduction zone that last hosted a great earthquake in 1877. The sequence opened >3700 surface cracks in the ...
Magnitude, timing, and rate of slip along the Atacama fault system, northern Chile: implications for Early Cretaceous slip partitioning and plate convergence
(GEOLOGICAL SOC PUBL HOUSE, 2021)
Displacement estimates along the Atacama fault system (AFS), a crustal-scale sinistral structure that accommodated oblique convergence in the Mesozoic Coastal Cordillera arc, vary widely due to a lack of piercing points. ...
The role of interplate locking on the seismic reactivation of upper plate faults on the subduction margin of northern Chile
(Nature, 2021)
Quaternary deformation in the northern Chile forearc is controlled by trench parallel shortening along reactivated Mesozoic faults. Dextral strikes-slip is expressed in NW-SE striking faults of the Atacama Fault System, ...
Seismic structure of the north-central Chilean convergent margin: Subduction erosion of a paleomagmatic arc
(AGU, 2014)
We study the erosive convergentmargin of north-central Chile (at ~31°S) by using high-resolution
bathymetric, wide-angle refraction, and multichannel seismic reflection data to derive a detailed
tomographic 2-D velocity-depth ...
Uplift of the Altiplano-Puna plateau: A view from the west
(American Geophysical Union, 2010-10)
The western flank of the Central Andean Plateau is a crustal‐scale monoclinal fold, expressed in the geomorphology and in the westward tilt of fore‐arc basin strata. Data from three fore‐arc basins quantify the magnitude ...
Permanent fore-arc extension and seismic segmentation: Insights from the 2010 Maule earthquake, Chile
(2013)
Geologists have long known that young normal faults are an important structural element of the Andean Coastal Cordillera, but their relationship to the subduction seismic cycle is still unclear. Some of the largest aftershocks ...
