Active deformation in the southern Andes from GPS and FEM models
Räumliche und zeitliche Variationen der Oberflächendeformation entlang von Subduktionszonen geben wichtige Informationen zum Verständnis des Ablaufs von schweren Erdbeben. In dieser Arbeit werden Beobachtungen der gegenwärtigen Deformation der Erdkruste und numerische Modellierungen präsentiert, um …

A Geophysical Survey Of Active Volcanism In The Central And Southern Andes
… Zone (CVZ) between 15°S and 28°S and the Southern Volcanic Zone (SVZ) between 33°S and 46°S are separated by a zone of flat slab subduction and differ significantly in the manifestation of current volcanic activity. The CVZ has been considered less hazardous due to the few number of …

Evolutionary Assembly of the Neotropical Montane Avifauna
… originated in disjunct geographic areas (e.g., Southern Andes, Northern Andes, or Central American mountains), and subsequently occupied the entire Neotropical montane region. In the fourth chapter, I conducted a more in-depth investigation of the role niche breadth and elevational distribution …

INTEGRATING GEOPHYSICAL METHODS TO STUDY SUBDUCTION ZONE PROPERTIES, ACTIVE FAULTING IN A VOLCANIC FIELD, AND VOLCANO LANDSLIDE HAZARDS
… of the Laguna del Maule volcanic field in the southern Andes of Chile, and 3) the edifice of Iliamna Volcano in the US state of Alaska. Active seismic and acoustic methods provide high resolution (down to cm-scale) studies of the upper crust (meters to tens of km), enabling analysis of physical …

Pliocene-Pleistocene landscape evolution in south-central Chile : interactions between tectonic, geomorphic, and climatic processes
… markers in natural environments. The Cenozoic Andes are an ideal setting to evaluate tectonic and climatic aspects of landscape evolution at different time and length scales in different natural compartments. The Andean Cordillera constitutes the type subduction orogen and is associated with …

Provenance of Eastern Magallanes Foreland Basin Sediments: Mineralogical and Geochemical Analyses Reveal Paleogene Tectonic Unroofing of the Fuegian andes
<p>Though southern South America and the Antarctic Peninsula were previously connected through a Paleozoic-Mesozoic subduction system on the western margin of Gondwana, this connection was tectonically disrupted in the Cenozoic by forming the Drake Passage in the Scotia Sea. Heavy mineral …

Cenozoic foreland-basin evolution in the northern Andes : insights from thermochronology and basin analysis in the Eastern Cordillera, Colombia
… orogen. While widely studied in the central and southern Andes, the spatial and temporal evolution of the Cenozoic foreland basin system in the northern Andes has received considerably less attention. This is in part due to the complex geodynamic boundary conditions, such as the oblique …
