摘要:... If the locations of initial volcanism are calculated using the eastward velocity of the Nazca plate, there appears to be a progression of younger volcanism toward the east, opposite what would be expected from a fixed mantle plume source. The rate that initial volcanism mov...

摘要:Abstract(#br)The ridge push force and the total lithospheric strength of the Nazca plate are compared along an East-West transect from the East Pacific Rise to the Peru–Chile trench at latitude 12°S. The thermal structure of the plate is estimated from the plate cooling m...

摘要:Abstract(#br)Guided wave dispersion is observed from earthquakes at 180–280 km depth recorded at stations in the fore-arc of Northern Chile, where the 44 Ma Nazca plate subducts beneath South America. Characteristic P-wave dispersion is observed at several stations in the ...

摘要:Abstract(#br)We define subducting plate geometries in the Nazca subduction zone by (re)locating intra-slab earthquakes in southern Peru (14–18°S) and using previously published converted phase analysis results to clarify the slab geometry and inferred relationships to the ...

摘要:Abstract(#br)This work concentrates on the determination of detailed variations of stress in the descending Nazca plate and is based on the distribution of seismic activity and the orientation of P- and T-axes of fault plane solutions. International Seismological Centre (ISC) an...

摘要:Abstract(#br)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 and 35°S. The interest zone located in the transition section where the Nazca plate changes from flat s...

摘要:Abstract(#br)Along the Peru-Chile trench, the subduction of the Nazca Plate under South America is well underlined by the Wadati Benioff zone. In the Central Andes, the seismicity defines a moderately deepening slab down to about 325 km. The occurrence of a scarce seismicity...

摘要:... The oceanic Nazca Plate shows negative relative to the sounding normal oceanic crust, ENE-WSW gravity anomalies highlighting the Carnegie Ridge, surrounded by highs corresponding to standard oceanic lithosphere. New gravity field profiles at 1°S and 4°S show Bouguer anomal...

摘要:... These results allow a high resolutiondefinition of the Nazca plate geometry in NW Perú. Focal mechanisms computed for 22 earthquakes located between 50 and 120 km depth beneath the network suggest the development of deformation processes in direction par...

摘要:A geometric model for the subduction of the Nazca plate beneath the South American plate in southwestern of Colombia is proposed based on the relocation of hypocenters of local and distantearthquakes. By means of the simultaneous inversion of teleseismic P and SH body waves, th...
