Evidence for a correlation between total lead concentrations in soils and the presence of geological faults
(2017-09-01)
The emission of radon gas in regions of geological faults, during the radioactive decay of uranium and thorium, results in the formation of lead isotopes 210Pb, 208Pb, 207Pb and 206Pb. As a consequence, the lead contamination ...
Submarine earthquake rupture, active faulting and volcanism along the major Liquiñe-Ofqui Fault Zone and implications for seismic hazard assessment in the Patagonian Andes
(2013)
The Liquiñe-Ofqui fault zone (LOFZ) in the Patagonian Andes is an active major transpressional intra-arc
fault system along which Quaternary faulting and volcanism develop. Subaerial and submarine geomorphologic and
structural ...
States of stress and slip partitioning in a continental scale strike-slip duplex: tectonic and magmatic implications by means of finite element modeling
(Elsevier, 2017)
Orogenic belts at oblique convergent subduction margins accommodate deformation in several trench parallel domains, one of which is the magmatic arc, commonly regarded as taking up the margin-parallel, strike-slip component. ...

Paleoseismology and global positioning system: earthquake-cycle effects and geodetic versus geologic fault slip rates in the Eastern California shear zone
(Geological Society of America, 2003)
Published slip rates for the Owens Valley fault zone in eastern California based on geodetic data and elastic half-space models (5–7 mm/yr) are faster than longer term geologic rates (2–3 mm/yr). We use Global Positioning ...
The transpressive southern termination of the Bucaramanga fault (Colombia): Insights from geological mapping, stress tensors, and fractal analysis

The use of apatite fission track thermochronology to constrain fault movements and sedimentary basin evolution in northeastern Brazil
(Elsevier B.V., 2005-12-01)
An apatite fission track study of crystalline rocks underlying sedimentary basins in northeastern Brazil indicate that crustal blocks that occur on opposite sides of a geological fault experienced different thermal histories. ...
Seismicity and tectonics
(Earthquake Engineering Research Institute, 2003)
The Southern Peru earthquake of 23 June 2001 resulted from thrust faulting on the boundary between the Nazca and South American plates. In terms of seismic moment release, the Mw (HRV) 8,4 earthquake was arguably the largest ...
Source mechanism of earthquake in Peru
(Springer, 2001-10)
The source mechanism of 19 earthquakes that occurred in Peru (1990–1996) is studied using broad band data. Focal mechanisms are obtained using polarities of P wave and body wave form inversion. Shallow earthquakes show ...
