Seismicity and state of stress in the central and southern Peruvian flat slab
(Elsevier, 2016-05)
We have determined the Wadati–Benioff Zone seismicity and state of stress of the subducting Nazca slab beneath central and southern Peru using data from three recently deployed local seismic networks. Our relocated hypocenters ...
Transient plate contraction between two simultaneous slab windows: Insights from Paleogene tectonics of the Patagonian Andes
(Pergamon-Elsevier Science Ltd, 2018-11)
Plate kinematic reconstructions show that the Farallon-Phoenix (Aluk) spreading center subducted under South America sometime between the Late Cretaceous and the Paleogene periods. Geological studies have supported a ...
Hydrochemical, Isotopic, and Geophysical Studies Applied to the Evaluation of Groundwater Salinization Processes in Quaternary Beach Ridges in a Semiarid Coastal Area of Northern Patagonia, Argentina
(Molecular Diversity Preservation International, 2021-12)
Quaternary sea level fluctuations have led to the development of beach ridges on many South Atlantic coasts. The objective of this paper was to asses from lithological, hydrochemical, iso-topic, and geophysical studies the ...

The Farallon-Aluk ridge collision with South America: Implications for the geochemical changes of slab window magmas from fore- to back-arc
(Elsevier, 2013-07)
The collision of a divergent ocean ridge may evolve into two end cases: in the continuity of ocean-floor subduction, or in the detachment of the subducted plate. The northern Patagonia active plate margin has the unique ...

Seismic velocity structure in the area of the 2007, Mw 8.0, Pisco-Peru earthquake: implications for the mechanics of subduction in the vicinity of the Nazca ridge
(Hindawi, 2020-11-06)
In this study, we present a velocity model for the area of the 2007 Pisco-Peru earthquake (Mw = 8.0) obtained using a double-difference tomography algorithm that considers aftershocks acquired for 6 months. The studied ...
Fully Adaptive Ridge Detection Based on STFT Phase Information
(Institute of Electrical and Electronics Engineers, 2020-04)
This letter deals with the problem of the estimation of the instantaneous frequencies of the modes of multicomponent signals from their linear time-frequency representations. In most approaches, such an estimation consists ...
