(Oxford University Press, 2016)Powerful subduction zone earthquakes rupture thousands of square kilometres along continental margins but at certain locations earthquake rupture terminates. To date, detailed knowledge of the parameters that govern seismic ...
-
(Elsevier, 2012)On 27 February 2010 the Mw 8.8 Maule earthquake in Central Chile ruptured a seismic gap where significant strain had accumulated since 1835. Shortly after the mainshock a dense network of temporary seismic stations was ...
-
(Universidad de Chile, 2016)El valle de Lonquimay (38.46°S) se localiza en el extremo septentrional de la Zona de Falla Liquiñe-Ofqui, que se extiende por 1200 km como un sistema transcurrente dextral y que es el elemento estructural dominante del ...

Caracterización sísmica del antearco marino en la zona epicentral del mega-terremoto del Maule 2010 (Universidad de Chile, 2015)La acumulación y relajación de esfuerzos debido a la convergencia entre la Placa oceánica de Nazca y la Placa continental Sudamericana provoca en Chile terremotos de gran magnitud que pueden generar tsunamis, causando ...
-
(Nature Publishing Group, 2018)Fundamental processes of the seismic cycle in subduction zones, including those controlling the recurrence and size of great earthquakes, are still poorly understood. Here, by studying the 2016 earthquake in southern ...
-
(Universidad de Chile, 2016)La cuenca Pampa del Tamarugal, ubicada en la Depresión Central, entre los 20°20 -20°50 S, posee un relleno que se configura en superficie como un extenso pediplano interrumpido por cerros islas alineados en donde el substrato ...
-
(ELSEVIER, 2010)We report here the first detailed 2D tomographic image of the crust and upper mantle structure of a Cretaceous seamount that formed during the interaction of the Pacific plate and the Louisville hotspot. Results show ...
-
(Elsevier, 2015)Complexities in the rupture process during a megathrust earthquake can be attributed to the combined effect of inhomogeneous distribution of stress accumulated during the interseismic period and inho-mogeneous rheology of ...
-
(Universidad de Chile, 2013)Los procesos sismotectónicos de la Zona Central de Chile están relacionados con la subducción de la Placa de Nazca bajo la Placa Sudamericana. Sin embargo, la sismicidad cortical superficial en la zona central ha sido poco ...
-
(Universidad de Chile, 2012)Una sección sísmica de reflexión 2D, de alta resolución en el sector sur de la Cuenca de Arauco muestra rasgos estructurales relacionados a la compresión cenozoica andina y a los procesos tectónicos de subducción. La Cuenca ...
-
(Elsevier, 2018)The outer rise is a topographic bulge seaward of the trench at a subduction zone that is caused by bending and flexure of the oceanic lithosphere as subduction commences. The classic model of the flexure of oceanic ...
-
(Wiley, 2017)Subduction zones provide direct insight into plate boundary deformation and by studying these areas we better understand tectonic processes and variability over time. We studied the structure of the offshore subduction ...
-
(Oxford University Press, 2014)When describing the mechanical behaviour of the lithosphere modelled as a thin plate, the most important parameter corresponds to its flexural rigidity, which is commonly expressed through the effective elastic thickness, ...
-
(Universidad de Chile, 2012)El presente trabajo de tesis tiene como primer objetivo el estudiar y comparar diferentes modelos matemáticos basados en ecuaciones diferenciales parciales y métodos numéricos para modelar y calcular la flexura de una placa ...
-
(Elsevier, 2017)Subduction megathrust earthquakes show complex rupture behaviour and large lateral variations of slip. However, the factors controlling seismic slip are still under debate. Here, we present 2-D velocity-depth tomographic ...
-
(Elsevier, 2015)The Maule 2010 megathrust earthquake M-w 8.8 has been characterized by two coseismic high-slip patches (asperities) north and south of the epicenter, separated by a region of lower slip. Here, we invert full broadband ...
-
(American Geophysical Union, 2013)Seismic refraction studies of deep-crustal and upper mantle structure beneath some oceanic hotspot provinces reveal the presence of ultramafic bodies with P-wave velocities of Vp ~ 7.4–8.0 km/s lying at or above the Moho, ...
-
(Universidad de Chile, 2014)El presente trabajo de tesis aborda la caracterización cuantitativa de parámetros físicos relacionados a la tectónica de la cuña continental Chilena, con objeto de estudiar las variaciones del estado dinámico del margen ...
-
(Universidad de Chile, 2015)Las causas de los pulsos orogénicos de la cadena andina durante el Cenozoico, son aún un enigma, distintos autores han postulado que estos eventos, o fases compresivas, estarían gatillados por los cambios en el vector de ...
-
(Wiley-Blackwell, 2016)Reloca Slide is the relict of an similar to 24-km(3) submarine slope collapse at the base of the convergent continental margin of central Chile. Bathymetric and seismic data show that directly to the north and south of the ...
