The crust and uppermost mantle structure of Southern Peru from ambient noise and earthquake surface wave analysis
Central Andes flat subduction surface wave tomography
2014/4/10
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
2014/4/10
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...
Structure of the subduction system in southern Peru from seismic array data
the subduction system in southern Peru seismic array data
2014/4/10
The subduction zone in southern Peru is imaged using converted phases from teleseismic P, PP, and PKPwaves andPwave tomography using local and teleseismic events with a linear array of 50 broadband se...
Design and installation of a Prototype Geohazard Monitoring System near Machu Picchu, Peru
Design installation a Prototype Geohazard Monitoring System
2010/10/21
The town of Machu Picchu, Peru, serves the >700 000 tourists visiting Machu Picchu annually. It has grown threefold in population in the past two decades. Due to the limited low-lying ground, construc...
First-class meta-data: a step towards a highly reliable wireless seismic network in Peru
First-class meta-data a step towards a highly reliable wireless seismic network Peru
2014/4/10
A 200-mile long temporary sensor network is inherently fragile, yet domain scientists legitimately demand reliable sensor data capture and transport. We report here on a currently deployed and operati...
Geodetic, teleseismic, and strong motion constraints on slip from recent southern Peru subduction zone earthquakes
Geodetic teleseismic strong motion constraints on slip southern Peru subduction zone earthquakes
2014/4/9
We use seismic and geodetic data both jointly and separately to constrain coseismic slip from the 12 November 1996Mw7.7 and 23 June 2001Mw8.5 southern Peru subduction zone earthquakes, as well as two ...
Geodetic displacements and aftershocks following the 2001 Mw= 8.4 Peru earthquake: Implications for the mechanics of the earthquake cycle along subduction zones
Geodetic displacements aftershocks following 2001 Bmw= 8.4 Peru earthquake earthquake cycle along subduction zones
2014/4/15
We analyzed aftershocks and postseismic deformation recorded by the continuous GPS station AREQ following theMw= 8.4, 23 June 2001 Peru earthquake. This station moved by 50 cm trenchward, in a N235E ...
