Abstract:

Se analiza la ocurrencia de corrientes de detritos en una cuenca andina en la que no se dispone de información fluviométrica y que se desarrolla en los primeros contrafuertes de la Cordillera de Los Andes, en una zona cercana a la ciudad de Santiago, Chile. Se estiman los caudales líquidos asociados a los mayores eventos históricos que de acuerdo a la literatura pueden clasificarse como flujos de barro o de detritos y se analiza la forma tradicional de determinación de caudales de diseño en cuencas pluvionivales. Dada la incidencia que estos eventos tienen sobre la población de zonas aledañas

Las formas en que las personas explican los desastres “naturales”, el rol que juega la ciencia, los expertos y el saber “técnico”, permiten dar cuenta de cómo el aluvión de 1993 no se puede entender solamente desde la naturaleza. En un primer momento, este artículo revisa procesos y decisiones que permiten entender los efectos del aluvión de 1993 en la Quebrada de Macul, comuna de La Florida, Santiago, Chile. A través de los relatos de diferentes actores afectados por el desastre y la revisión de archivos guardados por protagonistas de la catástrofe, vemos cómo estos perciben y describen el al

Abstract:

Landslide disaster risks increase worldwide, particularly in urban areas. To design and implement more effective and democratic risk reduction programs, calls for transdisciplinary approaches have recently increased. However, little attention has been paid to the actual articulation of transdisciplinary methods and their associated challenges. To fill this gap, we draw on the case of the 1993 Quebrada de Macul disaster, Chile, to propose what we label as the Geo-Social Model. This experimental methodology aims at integrating recursive interactions between geological and social factors configur

Most of them are recognized as a unique taxon, corresponding to the genus Archaeohyrax, characterized by the presence of a strong, shallow, wide sulcus on the labial side of the talonid of m3.

AbstractA distinct feature of many of the earliest archaeological sites (13,000-11,200 cal yr BP) at the core of the Atacama Desert is that they lie at or just below the surface, often encased in desert pavements. In this study, we compare these sites and undisturbed desert pavements to understand archaeological site formation and pavement development and recovery. Our results indicate these pavements and their soils are poorly developed regardless of their age. We propose that this is because of sustained lack of rain and extreme physical breakdown of clasts by salt expansion. Thus, the core

Las precipitaciones intensas en zonas desérticas son un fenómeno escaso. Sin embargo, cada ciertotiempo estos fenómenos pueden ocurrir, como sucedió en el año 1997, en la zona sur del Desierto deAtacama, Chile. El área de estudio, la cuenca del río Copiapó es un área intensamente explotada confines agrícolas, con viñedos para la producción de uva de mesa de exportación, que son regados conagua del río Copiapó y de los acuíferos subterráneos. La actividad agrícola se centra principalmenteen el fondo de valle, en laderas y conos aluviales, como también en subcuencas que se activan encaso de even

Abstract:

Abstract The Collahuasi district of northern Chile hosts several late Eocene-early Oligocene world-class porphyry Cu-Mo deposits, including Rosario, Ujina, and Quebrada Blanca deposits, and associated high-sulfidation epithermal mineralization at La Grande. Mineralization is hosted by intermediate to felsic intrusive and volcanic rocks of the upper Paleozoic to Lower Triassic Collahuasi Group, which experienced lower greenschist facies regional metamorphism prior to mineralization. Extensive hydrothermal alteration zones surround the porphyry and epithermal deposits, associated with hypogene o

Abstract:

Abstract. Rain-induced flash floods are common events in regions near mountain ranges. In peri-urban areas near the Andes the combined effects of the changing climate and El Niño–Southern Oscillation (ENSO) have resulted in an alarming proximity of populated areas to flood-prone streams, increasing the risk for cities and infrastructure. Simulations of rapid floods in these watersheds are particularly challenging, due to the complex morphology, the insufficient hydrometeorological data, and the uncertainty posed by the variability of sediment concentration. High concentrations produced by hill
