Fault resistance and soil resistivity influence on the impedance based methods for locating faults. a comparative analysis
(Universidad Nacional de Colombia Sede Medellín, 2010)
The influence of the soil resistivity and the fault resistance is considered in this paper where a comparison of a well defined impedance based method for locating faults is presented. Tests were performed in a real power ...
Fault diagnosis on electrical distribution systems based on fuzzy logic
(Lecture Notes in Computer Science, 2018)
Tectonic styles and crustal shortening of the Central Andes “Pampean” flat-slab segment in northern Chile (27–29°S)
The Andean orogenic belt, located in the Central Andes "Pampean flat-slab" segment in northern Chile (27-29 degrees S), is composed of two major tectonic regions: the Coastal Cordillera and the Frontal Cordillera. To ...
Active faulting, submarine surface rupture, and seismic migration along the liquine-ofqui fault system, Patagonian Andes
(Amer Geophysical Union, 2020)
The intra-arc Liquine-Ofqui Fault System (LOFS) is an active transpressive fault zone located in the Patagonian Andes of Chile. In 2007, a seismic sequence occurred in the Aysen Fjord region of Chilean Patagonia along the ...
Reactivation of fault systems by compartmentalized hydrothermal fluids in the southern Andes revealed by magnetotelluric and seismic data
(American Geophysical Union., 2020)
In active volcanic arcs such as the Andean volcanic mountain belt, magmatically sourced fluids are channeled through the brittle crust by faults and fracture networks. In the Andes, volcanoes, geothermal springs, and ...
Seismicity in a Transpressional Volcanic Arc: The Liquine-Ofqui Fault System in the Puyuhuapi Area, Southern Andes, Chile (44 degrees S)
(Amer Geophysical Union, 2020)
Understanding the relationship between crustal faults and volcanic activity in transpressional environments is a main goal in geosciences and could help to understand geothermal resources and evaluate geological hazards. ...
ESTRATEGIA DE REDUCCIÓN PARA LA APLICACIÓN GENERALIZADA DE LOCALIZADORES DE FALLAS EN SISTEMAS DE DISTRIBUCIÓN DE ENERGÍA ELÉCTRICA (REDUCTION STRATEGY FOR GENERALIZED APPLICATION OF FAULT LOCATORS IN ELECTRIC POWER DISTRIBUTION SYSTEMS)
(Fondo Editorial EIA - Universidad EIA, 2013-11-07)
En este artículo se presenta una estrategia generalizada para llevar a cabo la reducción de sistemas de distribución ramificados a alimentadores radiales equivalentes, como procedimiento básico para la aplicación generalizada ...
Fracture network, fluid pathways and paleostress at the Tolhuaca geothermal field
In this study, we examine the fracture network of the Tolhuaca geothermal system located in the Southern Andean volcanic zone that may have acted as a pathway for migration and ascent of deepseated fluids under the ...
Improving seismotectonics and seismic hazard assessment along the San Ramo´n Fault at the eastern border of Santiago city, Chile
The San Ramo´n Fault is an active west-vergent thrust fault system located along the eastern border of the city of Santiago, at the foot of the main Andes Cordillera. This is a kilometric crustal-scale structure recently ...
Crack formation on top of propagating reverse faults of the Chuculay Fault System, northern Chile: Insights from field data and numerical modelling
(PERGAMON-ELSEVIER SCIENCE, 2008)
Reverse faults in northern Chile have formed 20-300 m high scarps that contain open fractures which occur in a zone of 20-1600 m wide. Two-dimensional numerical models were used to explore the geometrical and mechanical ...
