When it comes to amphibian and reptile biodiversity, the eastern slopes of the Andes Mountains in South America stand out. A new survey of "herps" in and around Manu National Park in Peru by the Unive...
The crust and uppermost mantle structure of Southern Peru from ambient noise and earthquake surface wave analysis
Central Andes flat subduction surface wave tomography
2013/12/17
Southern Peru is located in the northern Central Andes, which is the highest plateau along an active subduction zone. In this region, the Nazca slab changes from normal to flat subduction, with the as...
Locating a scatterer in the active volcanic area of Southern Peru from ambient noise cross-correlation
Interferometry Wave scattering and diffraction Volcanic arc processes
2012/12/5
We report on a strong scatterer of seismic energy in the 5–10 s period range located in the volcanic arc of Southern Peru. It is superficially like an active noise source in that it produces a continu...
