  • Impact of the 1960 Major Subduction Earthquake in Northern Patagonia (Chile, Argentina)
    ARTICLE IN PRESS Quaternary International 158 (2006) 58–71 Impact of the 1960 major subduction earthquake in Northern Patagonia (Chile, Argentina) Emmanuel Chaprona,b,Ã, Daniel Arizteguic, Sandor Mulsowd, Gustavo Villarosae, Mario Pinod, Valeria Outese, Etienne Juvignie´f, Ernesto Crivellie aRenard Centre of Marine Geology, Ghent University, Ghent, Belgium bGeological Institute, ETH Zentrum, Zu¨rich, Switzerland cInstitute F.A. Forel and Department of Geology and Paleontology, University of Geneva, Geneva, Switzerland dInstituto de Geociencias, Universidad Austral de Chile, Valdivia, Chile eCentro Regional Universitario Bariloche, Universidad Nacional del Comahue, Bariloche, Argentina fPhysical Geography,Universite´ de Lie`ge, Lie`ge, Belgium Available online 7 July 2006 Abstract The recent sedimentation processes in four contrasting lacustrine and marine basins of Northern Patagonia are documented by high- resolution seismic reflection profiling and short cores at selected sites in deep lacustrine basins. The regional correlation of the cores is provided by the combination of 137Cs dating in lakes Puyehue (Chile) and Frı´as (Argentina), and by the identification of Cordon Caulle 1921–22 and 1960 tephras in lakes Puyehue and Nahuel Huapi (Argentina) and in their catchment areas. This event stratigraphy allows correlation of the formation of striking sedimentary events in these basins with the consequences of the May–June 1960 earthquakes and the induced Cordon Caulle eruption along the Liquin˜e-Ofqui Fault Zone (LOFZ) in the Andes. While this catastrophe induced a major hyperpycnal flood deposit of ca. 3 Â 106 m3 in the proximal basin of Lago Puyehue, it only triggered an unusual organic rich layer in the proximal basin of Lago Frı´as, as well as destructive waves and a large sub-aqueous slide in the distal basin of Lago Nahuel Huapi.

  • Geographical Data of Chilean Lizards and Snakes in the Museo Nacional De Historia Natural Santiago, Chile
    GEOGRAPHICAL DATA OF CHILEAN LIZARDS AND SNAKES IN THE MUSEO NACIONAL DE HISTORIA NATURAL SANTIAGO, CHILE HERMAN NUNEZ Seccion Zoologia Museo Nacional de Historia Natural SMITHSONIAN HERPETOLOGICAL INFORMATION SERVICE NO. 91 1992 SMITHSONIAN HERPETOLOGICAL INFORMATION SERVICE The SHIS series publishes and distributes translations, bibliographies, indices, and similar items judged useful to individuals interested in the biology of amphibians and reptiles, but unlikely to be published in the normal technical journals. Single copies are distributed free to interested individuals. Libraries, herpetological associations, and research laboratories are invited to exchange their publications with the Division of Amphibians and Reptiles. We wish to encourage individuals to share their bibliographies, translations, etc. with other herpetologists • through the SHIS series. If you have such items please contact George Zug for instructions on preparation and submission. Contributors receive 50 free copies. Please address all requests for copies and inquiries to George Zug, Division of Amphibians and Reptiles, National Museum of Natural History, Smithsonian Institution, Washington DC 20560 USA. Please include a self-addressed mailing label with requests. INTRODUCTION The herpetological collections of the Museo Nacional de Historia Natural (MNHNC) contains about 3500 amphibians and reptiles. Nearly 90% of the specimens are lizards, and of these, most are Liolaemus , the most diversified member of the Chilean herpetofauna. The specimens of Liolaemus derive mainly from "central Chile", i.e., the area between the city of La Serena and the Biobio River. Both northern and southern Chile are relatively unexplored; thus, the taxonomy and composition of these herpetof aunas is less well known. The distribution of Chilean lizards and snakes has not received much attention (however, see Valencia & Velosa 1981, Velosa & Navarro 1988) beyond the general information provided by Peters & Donoso-Barros (1970) and Donoso-Barros (1966, 1970).

  • Ciudades, Pueblos, Aldeas Y Caseríos 2019
    CIUDADES, PUEBLOS, ALDEAS Y CASERÍOS 2019 INSTITUTO NACIONAL DE ESTADÍSTICAS Marzo / 2019 PRESENTACIÓN El Instituto Nacional de Estadísticas (INE) da a conocer en esta publicación la edición actualizada de “Ciudades, pueblos, aldeas y caseríos”, tomando como base la información del Censo de Población y de Vivienda, realizado el 19 de abril de 2017. Consciente de la importancia de la planificación regional, provincial y comunal, el INE aporta en este documento datos pertinentes sobre las ciudades, pueblos, aldeas, caseríos, seleccionando las variables esenciales que caracterizan su población y vivienda. Así, este texto entrega cifras actualizadas, datos de población desagregados por sexo, recuentos sobre viviendas particulares, superficie de ciudades y pueblos del país y recientes modificaciones. Esta publicación marca, además, un hito en las definiciones geográficas del INE, ya que en ella se presenta la nueva conceptualización de ciudad, en la que se consideran las características político- administrativas de la categorización. Los antecedentes aquí desplegados quedan a disposición de instituciones públicas y privadas, consultoras, estudiantes, profesionales y usuarios en general. 2 CONSIDERACIONES CONCEPTUALES División geográfica censal: El territorio comunal se divide en distritos, los que pueden ser urbanos, rurales o mixtos. A su vez, en el área urbana se reconocen zonas censales y en el área rural, localidades. Las zonas censales se componen de manzanas y las localidades, de entidades, las que también tienen sus propias categorías. Los límites censales los define el INE y se encuentran sostenidos y enmarcados en los límites de la división político-administrativa (DPA). Sin embargo, su trazado no reviste un carácter legal.

You can see other volcanoes in Argentina and Chile along the same fault line as Puyehue: Lanin, Osorno, Puntiagudo, and Tronador. According to conditions, we can ski from the summit into the crater of the volcano, skin/boot pack out of the crater, choose another line, and ski down again! The lines we ski, and the number of runs we ski, is dependent on skiers' skill level and endurance. This is a long day on the volcano and we ski back to the hut. Spend the night in the mountain hut. Day 5 Ski and hike down to the gaucho's ranch. Options are to relax that afternoon or drive to Pucon.
