Seismic structure and tectonics of the continental wedge overlying the source region of the Iquique Mw8.1 2014 earthquake
(Elsevier, 2020)
On April 1, 2014, a large earthquake (Mw = 8.1) ruptured the central part of a historic seismic gap in northern Chile. In order to study the relationship between the co-seismic rupture characteristics and the crustal ...
Retrieving shallow shear-wave velocity profiles from 2D seismic-reflection data with severely aliased surface waves
(Elsevier Science, 2019-02)
The inversion of surface-wave phase-velocity dispersion curves provides a reliable method to derive near-surface shear-wave velocity profiles. In this work, we invert phase-velocity dispersion curves estimated from 2D ...
Strike-slip related folding within the Malvinas/Falkland Trough (south-western Atlantic ocean)
(Pergamon-Elsevier Science Ltd, 2020-03)
The Malvinas/Falkland Trough (M/FT) is an E-W trending bathymetric depression along which runs the present-day South American-Scotia plate boundary. To the north of the M/FT lies the southern sector of the South Malvinas/Falkland ...
Geometry and late Mesozoic-Cenozoic evolution of the Salar de Atacama Basin (22°30′-24°30′S) in the northern Central Andes: New constraints from geophysical, geochronological and field data
(Elsevier B.V., 2019)
The late Mesozoic-Cenozoic evolution of the Central Andes of northern Chile consists of a series of events related to changing conditions along the plate margin, leading to different episodes of compression and extension. ...
Western Scotia Sea margins: Improved constraints on the opening of the Drake Passage
(American Geophysical Union, 2006-06)
We present a revised tectonic interpretation (from ∼28 Ma to 3.2 Ma) of the western sector of the Scotia Sea, incorporating new multichannel seismic reflection profiles and magnetic anomaly identifications for the continental ...
What is the structure of the forearc region in the Central Andes of northern Chile?: An approach from field data and 2-D reflection seismic data
(Elsevier Science, 2019-10)
The tectonic evolution of the Andean forearc in the Central Andes is understood by the superimposition of deformational events associated with different tectonic regimes, which control the main morpho-tectonic units of ...
The Late-Quaternary deposits of the Piedra Buena Terrace (Patagonian continental slope, SW Atlantic): An example of interaction between bottom currents and seafloor morphology
(Elsevier Science, 2021-05)
The Piedra Buena Terrace (PBT), situated in the Patagonian continental slope, is swept by the vigorous flow of Antarctic-sourced bottom water masses, and intersected by a considerable submarine canyon system. It thus ...
