Lithospheric structure of Pampean Flat Slab (latitude 30-33°s) and Northern Costa Rica (latitude 9-11°n) Subduction Zones
The Pampean flat slab subduction in west-central Argentina (latitude 30-33S) and the steeply dipping Northern Costa Rica subduction zone (latitude 9-11N) show significant along-trench variations in both the subducting and ...
Nature of crustal terranes and the Moho in northern Costa Rica from receiver function analysis
The Central American subduction zone in northern Costa Rica shows along‐strike variations in both the incoming and overriding plates. By analyzing the subducting oceanic Moho (M1) and the upper plate Moho (M2) with receiver ...
Lithospheric Structure of the Pampean Flat Slab Region from Double-Difference Tomography
We obtain earthquake locations and a detailed three-dimensional velocity model of the flat slab subduction zone in west-central Argentina (latitudes: 32-30°S and longitudes: 70-66°W) using a regional-scale doubledifference ...
Continental and oceanic crustal structure of the Pampean flat slab region, western Argentina, using receiver function analysis: New high-resolution results
The Pampean flat slab of central Chile and Argentina (30◦–32◦S) has strongly influenced Cenozoic tectonics in western Argentina, which contains both the thick-skinned, basementcored uplifts of the Sierras Pampeanas and the ...
Crustal seismicity in the Andean Precordillera of Argentina using seismic broadband data
In this study, we analyze 100 crustal Precordilleran earthquakes recorded in 2008 and 2009 by 52 broadband seismic stations from the SIEMBRA and ESP, two temporary experiments deployed in the Pampean flat slab region, ...
