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 ...
Subdivision of the Nazca Plate into three new tectonic plates and it’s incident with the peruvian current seismicitySubdivisión de la Placa de Nazca en tres nuevas placas tectónicas y su incidencia con la sismicidad peruana actual

Strain rate of the South American lithospheric plate by SIRGAS-CON geodetic observations
(2013-08-28)
A multiyear solution of the SIRGAS-CON network was used to estimate the strain rates of the earth surface from the changing directions of the velocity vectors of 140 geodetic points located in the South American plate. The ...
Strain rate of the South American lithospheric plate by SIRGAS-CON geodetic observations
(2013-08-28)
A multiyear solution of the SIRGAS-CON network was used to estimate the strain rates of the earth surface from the changing directions of the velocity vectors of 140 geodetic points located in the South American plate. The ...
Seismic-gravimetric analysis of the subducted Nazca plate 1 between 32°S and 36°S
(Science Press, 2018-01)
The study region is seismically and tectonically characterized by the angle variations in the subduction of the Nazca plate. The results obtained from earthquakes location between 32° and 36°S latitude and 67°–71°W longitude ...
Decelerating Nazca-South America and Nazca-Pacific plate motions
(American Geophysical Union, 1999)
Space geodetic estimates of the rate of Nazca-South America convergence and Nazca-Pacific spreading averaging over several years show that present day rates are significantly slower than the 3 million year average NUVEL-1A ...
S-Local-Wave Seismic Anisotropy in the Forearc Above the Subducted Nazca Plate Between 33°S and 34.5°S
(Birkhauser Verlag Ag, 2016-04)
S-wave splitting from local earthquakes within the Nazca plate that are deeper than the interplate seismogenic zone enabled the determination of the fast velocity direction, U, and the lag time, dt, in the forearc of the ...
Inferences on the geometry of the Nazca plate in northwestern Perú based on data collected by a local seismograph network
(Universidad Nacional de Colombia, 2006-01)
In Central and Southern Peru, local and teleseismic data allow having insights on the Wadati-Benioff zone (WBZ) geometry. In the region of Northern Perú, only rough estimates of the WBZ geometry have been proposed, and ...
New evidences of rupture of crust and mantle in the subducted Nazca plate at intermediate-depth
(Pergamon-Elsevier Science Ltd, 2015-03)
Between 33°-36°S, the Nazca plate subducts below South American plate with an angle of ~30°, and it is seismically active until ~200-280km depth. At 33.5°S, the seismicity decreases drastically at 120km depth, just below ...
