Upper mantle anisotropy beneath Peru from SKS splitting: constraints on flat slab dynamics and interaction with the Nazca Ridge
(Elsevier, 2015-02)
The Peruvian flat slab is by far the largest region of flat subduction in the world today, but aspects of its structure and dynamics remain poorly understood. In particular, questions remain over whether the relatively ...
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 ...

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 ...
Predicted path for hotspot tracks off South America since Paleocene times: Tectonic implications of ridge-trench collision along the Andean margin
(Elsevier Inc., 2018)
Hotspots are generated by partial melting due to hot plumes rising within the Earth's mantle, and when tectonic plates move relative to the plume source, hotspot tracks form. Off South America, the oceanic Nazca Plate hosts ...
Oroclinal bending of the Juan Fernandez Ridge suggested by geohistory analysis of the Bahia Inglesa Formation, north-central Chile
(ELSEVIER SCIENCE BV, 2016)
The stratigraphy of the Bahia Inglesa Formation in the Caldera Basin west of Copiapo, (north-central Chile) is revised, based on hitherto unpublished stratigraphic sections and Sr-87/Sr-86 dating. The depositional environment ...
