The aftershock distribution of the 2014 Mw 8.1 Iquique earthquake offshore northern Chile, identified from a long-term deployment of ocean bottom seismometers installed eight months after the mainshock, in conjunction with ...

© 2019 Elsevier B.V.Aftershocks of the 16 September 2015 M8.3 Illapel earthquake in central Chile were recorded for a period of one year by the Chile-Illapel Aftershock Experiment (CHILLAX) seismic network. An initial ...

The uplift and evolution of a noncollisional orogen developed along a subduction zone, such as the Andean system, is a direct consequence of the interrelation between plate tectonic stresses and erosion. Tectonic stresses ...

Reconfigurations of magmatic arcs through time have been recognized since pioneering works, describing inland and trenchward arc migrations or magmatic shut-off lasting for several millions of years. These modifications ...

The pre- and current collision of the Juan Fernandez Ridge with the central Chilean margin at 31 degrees-33 degrees S is characterized by large-scale crustal thinning and long-term subsidence of the submarine forearc caused ...

Based on high-resolution bathymetry and geophysical observations, the precise continental wedge geometry along the Chileanmargin is analyzed. The data showcomplex patterns in continentalwedge geometry that challenge the ...

The process of flat-slab subduction results in complex deformation of overlying forearcs, yet how this deformation decays with distance away from the zone of underthrusting is not well understood. In south central Alaska, ...
