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 ...
Dots-and-Lines Approach to Subduction Volcanism and Tectonics「点と線」に注目した沈み込み帯の火山とテクトニクス
(Tokyo Geographical Society, 2017-04)
Anomalous arc volcanoes tend to exist where a linear topographic feature (fracture zone, line of seamounts, or ridge) on the oceanic plate is subducting. “Dots-and-lines tectonics” are proposed for clarifying this tendency ...
Thick, strong sediment subduction along south-central Chile anditsrole ingreat earthquakes
(Elsevier, 2020)
The south-central Chile margin experienced the largest and sixth largest earthquakes ever recorded - the 1960 Mw 9.5 Valdivia and 2010 Mw 8.8 Maule megathrust earthquakes, respectively. In early 2017, we conducted a seismic ...
High-resolution image of the North Chilean subduction zone: seismicity, reflectivity and fluids
(2014)
We obtained high-precision locations for 5250 earthquakes in the Iquique segment of the northern Chilean subduction zone from two temporary local seismic networks around 21°S. A double seismic zone in the downgoing Nazca ...
Depth-dependent geometry of margin-parallel strike-slip faults within oblique subduction zones
(2017)
Based on the principle that faults develop where shear stress is maximum, we determine the depth-dependent geometry of margin-parallel strike-slip faults within oblique subduction zones. Using an elastic half-space model ...
Late Cenozoic to modern-day volcanism in the Northern Andes: A geochronological, petrographical, and geochemical review
(Springer Verlag, 2019-01-01)
The Northern Andean Block is the result of complex tectonic interaction between the Farallon-Nazca, South American, and Caribbean Plates. Abundant late Cenozoic volcanism (and associated hypabyssal porphyritic plutonism), ...
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 ...
A strong-motion database from the Peru–Chile subduction zone
(Springer, 2011)
Earthquake hazard along the Peru – Chile subduction zone is amongst the highest in the world. The development of a database of subduction-zone strong-motion recordings is, therefore, of great importance for ground-motion ...
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. ...
