Fluid and Melt Pathways in the Central Chilean Subduction Zone Near the 2010 Maule Earthquake (35–36°S) as Inferred From Magnetotelluric Data
(Blackwell Publishing Ltd, 2019)
©2019. American Geophysical Union. All Rights Reserved.The subduction zone of central Chile (36°S) has produced some of the world's largest earthquakes and significant volcanic eruptions. Understanding the fluid fluxes and ...
The flat to normal subduction transition study to obtain the Nazca plate morphology using high resolution seismicity data from the Nazca plate in Central Chile
(Elsevier Science, 2015-06)
Data from 45 seismological stations mostly temporary were used to obtain an accurate data set of intraslab seismicity of the Nazca subducted plate between 33°S to 35°S. The interest zone located in the transition section ...
The seismic coupling of subduction zones revisited
(ResearchGate, 2012)
The nature of seismic coupling for many of the world's subduction zones has been reevaluated. Geodetic estimates of seismic coupling obtained from GPS measurements of upper plate deformation during the interseismic period ...
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 ...
Density structure and geometry of the Costa Rican subduction zone from 3-D gravity modeling and local earthquake data
(2015-10-29)
The eastern part of the oceanic Cocos Plate presents a heterogeneous crustal structure due to diverse origins and ages as well as plate-hot spot interactions which originated the Cocos Ridge, a structure that converges ...
Plume overriding triggers shallow subduction and orogeny in the southern Central Andes
(Elsevier Science, 2017-09)
Plate tectonic theory implies that mantle plumes may be eventually overridden by lithosphere during continental drift. These events have particular tectonomagmatic consequences for active margins and hence related orogenic ...
Fluid Distribution in the Central Andes Subduction Zone Imaged With Magnetotellurics
(Blackwell Publishing Ltd, 2019)
We present a model of the electrical resistivity structure of the lithosphere in the Central Andes between 20° and 24°S from 3-D inversion of 56 long-period magnetotelluric sites. Our model shows a complex resistivity ...
