Nuevas evidencias de la actividad sísmica del terreno Cuyania en la región de subducción de placa horizontal de ArgentinaNew evidence for the seismic activity of the Cuyania terrane in the flat slab subduction region of Argentina

Alvarado, Patricia Monica; Sánchez, Gerardo; Saez, Mauro; Castro, Brigida Marta Ester (Universidad Nacional Autónoma de México. Centro de Geociencias, 2010-06)

El terreno Cuyania situado en la zona andina de trasarco entre 29°S y 34°S se compone de un sistema de corrimientos y retrocorrimientos del cinturón plegado de Precordillera y más hacia el este por bloques de basamento ...

Unexpected coseismic surface uplift at Tirúa-Mocha Island area of south Chile before and during the Mw 8.8 Maule 2010 earthquake: a possible upper plate splay faultAlzamiento cosísmico superficial inesperado en el área de Tirúa-isla Mocha del sur de Chile antes y durante el terremoto de Maule Mw=8,8 de 2010: una probable falla subsidiaria en la placa superior

Quezada, Jorge; Jaque, Edilia; Catalán, Nicole; Belmonte, Arturo; Fernández, Alfonso; Isla, Federico Ignacio (Servicio Nacional de Geología y Minería, 2020-04)

The Tirúa-Mocha Island area (38.2°-38.4° S) in southern Chile has been affected by two megaearthquakes in only 50 years: the 1960 Mw=9.5 Valdivia earthquake and 2010 Mw=8.8 Maule earthquake. We studied in the field the ...

The Santiago de Cuba earthquake of 11 June 1766: Some new insightsThe Santiago de Cuba earthquake of 11 June 1766: Some new insights

Cotilla Rodríguez, M. O. (Instituto de Geofísica, 2003)

Subduction system and flat slab beneath the Eastern Cordillera of Colombia

Chiarabba, Claudio; De Gori, Pasquale; Faccenna, Claudio; Speranza, Fabio; Seccia ,Danilo; Dionicio,Viviana; Prieto, Germán A.

Seismicity at the northern terminus of the Nazca subduction is diffused over a wide area containing the puzzling seismic feature known as the Bucaramanga nest. We relocate about 5000 earthquakes recorded by the Colombian ...

Inferences on the geometry of the nazca plate in northwestern perú based on data collected by a local seismograph network

Tavera, Hernando; Vilca, Renzo; Marín, Gloria (UNIVERSIDAD NACIONAL DE COLOMBIA, 2006)

In Central and Southern Peru, local and teleseismic data allow having insights on the Wadati-Benioff zone (WBZ) geometry. In the region of Northern Perú, only rough estimates of the WBZ geometry have beenproposed, and were ...

Electrical conductivity of the Pampean Shallow Subduction Region of Argentina near 33 S: evidence for a slab window

Burd, Aurora I.; Booker, John R.; Mackie, Randall; Pomposiello, Maria Cristina; Favetto, Alicia Beatriz (American Geophysical Union, 2013-08)

We present a three-dimensional (3-D) interpretation of 117 long period (20–4096 s) magnetotelluric (MT) sites between 31°S and 35°S in western Argentina. They cover the most horizontal part of the Pampean shallow angle ...

Extensión en el arco volcánico actual del sur del Perú

Benavente Escobar, Carlos Lenin; Carlotto Caillaux, Víctor Santiago; Del Castillo Herrera, Boris (Sociedad Geológica del PerúPE, 2010)

Durante la última década un tema de investigación es el Arco Volcánico Actual de los Andes Centrales, donde en base al cartografiado de sus depósitos volcánicos, estratigrafía, geoquímica, geocronología y hasta la aplicación ...

Lithospheric structure of the Pampean flat slab region from double-difference tomography

Linkimer, Lepolt; Beck, Susan; Zandt, George; Alvarado, Patricia Monica; Anderson, Megan; Gilbert, Hersh; Zhang, Haijiang (Pergamon-Elsevier Science Ltd, 2019-11)

We obtain earthquake locations and a detailed three-dimensional velocity model of the flat slab subduction zone in west-central Argentina (latitudes: 32-30°S and longitudes: 70-66°W) using a regional-scale double-difference ...
