An extensive compilation of crustal thicknesses is used to develop crustal models in
continental South America. We consider point crustal thicknesses from seismic refraction …

We present a new set of contour maps of the seismic structure of South America and the
surrounding ocean basins. These maps include new data, helping to constrain crustal …

Seismological data provide evidence of a depth-dependent rupture behaviour of
earthquakes occurring at the megathrust fault of subduction zones, also known as …

Giant earthquake (moment magnitude Mw≥ 8.5) forecasts for subduction zones have been
empirically related to both tectonic stresses and geometrical irregularities along the …

Whether subducted oceanic reliefs such as seamounts promote seismic rupture or aseismic
slip remains controversial. Here we use swath bathymetry, prestack depth‐migrated …

We used the receiver function technique to deduce crustal thickness beneath the
northwestern Andean system, using data from the permanent seismic network of Colombia …

Abstract At the North-Ecuadorian convergent margin (1° S–1.5° N), the subduction of the
rough Nazca oceanic plate leads to tectonic erosion of the upper plate and complex …

To improve earthquake location, we create a 3-D a priori P-wave velocity model (3-DVM)
that approximates the large velocity variations of the Ecuadorian subduction system. The 3 …

Accurate and precise 3-D geometry models of subduction zone plate boundaries are crucial
for advancing earthquake science, enhancing hazard assessments, and improving our …

Oceanic crust formed at slow-spreading ridges is currently subducted in only a few places
on Earth and the tectonic and seismogenic imprint of the slow-spreading process is poorly …
