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. ...
Interseismic deformation at subduction zones investigated by 2D numerical modeling: case study before the 2010 Maule earthquake
(2016)
We study interseismic deformation preceding the Mw8.8 2010 Maule earthquake by means of two-dimensional finite-element modeling. Our goal is to gain insight into the fundamental factors controlling elastic strain build-up ...
Oblique subduction and strain partitioning: Tectonic role of margin-parallel and margin-transverse structures at the Southern Volcanic Zone of the Andes
(2015)
Convergent margins undergoing oblique subduction develop margin-parallel structural domains, which accommodate the long-term crustal deformation within the overriding plate. Although the Andes are no exception, ...
Regional electrical structure of the Andean subduction zone in central Chile (35 degrees 36 degrees S) using magnetotellurics
(Springer, 2017)
A profile of broadband magnetotelluric stations was acquired between 2009 and 2016 at 35 degrees-36 degrees S in the Southern Volcanic Zone of the Chilean Andes to image the subduction zone and its relation with the volcanic ...
Jurassic-Early Cretaceous intermediate virtual geomagnetic poles and Pangaean subduction zones
(Elsevier Science, 2008-02)
The objective of this paper is to show that the distribution of Jurassic-Early Cretaceous intermediate virtual geomagnetic poles (VGPs) seems to be conditioned by Pangaean subducted slabs. Palaeomagnetic data from between ...
Deformational evolution of a Cretaceous subduction complex: Elephant Island, South Shetland Islands, Antarctica
(Elsevier B.V., 2000-03-30)
New structural data from Elephant Island and adjacent islands are presented with the objective to improve the understanding of subduction kinematics in the area northeast of the Antarctic Peninsula. on the island, a first ...

Three-dimensional elastic wave speeds in the northern Chile subduction zone: variations in hydration in the supraslab mantle
(Oxford University Press, 2016)
We use seismic tomography to investigate the state of the supraslab mantle beneath northern Chile, a part of the Nazca-South America Plate boundary known for frequent megathrust earthquakes and active volcanism. We performed ...
