Abstract This work aims to assess geothermal power potential in identified high enthalpy geothermal areas in the Chilean Andes, based on reservoir temperature and volume. In addition, we present a set of highly favorable geothermal areas, but without enough data in order to quantify the resource. Information regarding geothermal systems was gathered and ranked to assess Indicated or Inferred resources, depending on the degree of confidence that a resource may exist as indicated by the geoscientific information available to review. Resources were estimated through the USGS Heat in Place method. A Monte Carlo approach is used to quantify variability in boundary conditions.

The dataset shows con- straints on the nature of slab-derived component to mantle source. Analyzed samples show large negative Nb and Ta anomalies, and enrichment of alkaline earth elements and Pb, which are features of typical island arc volcanic rocks. Boron contents of SVZ volcanic rocks range 2.3–125.5 ppm, exhibiting marked enrichment relative to N-MORB and OIB. Both the boron contents and B/Nb ratios of the volcanic rocks increase from the southern SVZ (SSVZ) to central SVZ (CSVZ). Fluid mobile/immobile element ratios (B/Nb, Ba/Nb, Pb/Nb, and K/Nb) are used to examine slab-derived com- ponent to mantle source.

    Dynamical Regime and Advance Rate of Lava Flows Using Its Deposit Characteristics: 2 Cases from the Lonquimay and Villarrica

    IAVCEI 2013 Scientific Assembly - July 20 - 24, Kagoshima, Japan Forecasting Volcanic Activity - Reading and translating the messages of nature for society 0P2_3H-O11 Room A5 Date/Time: July 20 17:15-17:30 Dynamical regime and advance rate of lava flows using its deposit characteristics: 2 cases from the Lonquimay and Villarrica volcanoes, Southern Andes of Chile Maria Angelica Contreras1,2, Angelo Castruccio1,2 1Universidad de Chile, Chile, 2Centro de Excelencia en Geotermia de los Andes (CEGA), Chile E-mail: [email protected] The advance of lava flows is controlled by the effusion rate, rheology, topography and cooling effects. Consequently, the deposits of lava flows would reflect the interplay between these factors. We tested a methodology to estimate the variations of flow rate and velocity of ancient lava flows using its deposit dimensions, textural characteristics and petrography. We studied the deposits of two lava flows with contrasting styles generated during historical times in the Southern Andes of Chile: the 1971 eruption of Villarrica volcano and the 1988-89 eruption of Lonquimay volcano. Both eruptions have a record of its duration and advance rate, so we can test different dynamical models in order to fit better the available data. The Villarrica eruption lasted a couple of days and the resulting lava flow reached a length of 16.5 km, with thicknesses of 3-15 m, depending mainly on the channelling of the flow. The morphology is transitional between Pahoe-hoe and Aa. Clasts morphologies are mainly rubbly and slabby, ranging from a few cm to a couple of meters in diameter.

Guallatiri Volcano (18°25’S, 69°05’W) is a large edifice located on the Chilean Altiplano near the Bo- livia/Chile border. This Pleistocene-Holocene construct, situated at the southern end of the Nevados de Quimsachata chain, is an andesitic/dacitic complex formed of early stage lava flows and later stage coulées and lava domes.

    Southern Andes Supersite Coupled Geohazards at Southern Andes: Copahue-Lanín Arc Volcanoes and Adjacent Crustal Faults

    Version 1.3 15 October 2018 www.geo-gsnl.org Biennial report for Permanent Supersite/Natural Laboratory GeoHazSA: Southern Andes Supersite Coupled geohazards at Southern Andes: Copahue-Lanín arc volcanoes and adjacent crustal faults History https://geo-gsnl.org/supersites/permanent- supersites/southern-andes-supersite/ Supersite Coordinator Luis E. Lara, SERNAGEOMIN, CIGIDEN, Av. Santa María 0104, Santiago, CHILE 1 Version 1.3 15 October 2018 www.geo-gsnl.org 1. Abstract The Southern Andes (33°-46°S) is a young and active mountain belt where volcanism and tectonic processes pose a significant threat to the communities nearby. In fact, only recent eruptions caused evacuations of 250-3500 people and critical infrastructure is present there. The segment here considered corresponds to a low altitude orogen (<2000 masl on average) but characterized by a high uplift rate as a result of competing tectonic and climate forces. This Supersite focuses on a ca. 200 km long segment of the Southern Andes where 9 active stratovolcanoes (Copahue, Callaqui, Tolhuaca, Lonquimay, Llaima, Sollipulli, Villarrica, Quetrupillan and Lanín) and 2 distributed volcanic fields (Caburgua and Huelemolles) are located, just along a tectonic corridor defined by the northern segment of the Liquiñe-Ofqui Fault System (LOFS). Activity of the LOFS has been detected prior to some eruptions and coeval with some others. There are several tectonic and volcanic models to be investigated that derive from a strong two-way coupling between tectonics and volcanism, recently detected by either geophysical techniques or numerical modeling. Hazards in the segment derive mostly from the activity of some of the most active volcanoes in South America (e.g., Villarrica, Llaima), others with long-lasting but weak current activity (e.g., Copahue) or some volcanoes with low eruptive frequency but high magnitude eruptions in the geological record (e.g., Lonquimay).

    Recent Changes in Total Ice Volume on Volcán Villarrica, Southern Chile

    Nat Hazards DOI 10.1007/s11069-014-1306-1 ORIGINAL PAPER Recent changes in total ice volume on Volca´n Villarrica, Southern Chile Andre´s Rivera • Rodrigo Zamora • Jose´ Uribe • Anja Wendt • Jonathan Oberreuter • Sebastia´n Cisternas • Fernando Gimeno • Jorge Clavero Received: 3 October 2013 / Accepted: 13 June 2014 Ó The Author(s) 2014. This article is published with open access at Springerlink.com Abstract Results obtained by the first intensive airborne surveys carried out at Volca´n Villarrica (39°S) in Southern Chile, are presented. These campaigns included the use of a scanner laser system, for detecting the glacier surface topography, and a helicopter-borne ice penetrating radar, for measuring ice thicknesses. These surveys allowed determining the snow and ice volume storage at this volcano, volume which is susceptible to melt during eruptive events generating dangerous fast flows (lahars). Volca´n Villarrica is one of the most active volcanoes in Chile, with frequent eruptive events, many of them associated with lahars which are considered the most hazardous process at this volcano. In fact, most of the casualties and infrastructure damages incurred during historical eruptive events at the volcano are associated with lahars. With use of the radar and laser data, a total volume of 1.17 ± 0.1 km3 of water equivalent (w.eq.) at the volcano in 2012 was calculated, only 37 % of the estimated volume of 1961, a reduction mainly explained by the area shrinkage and ice thinning rates observed in the last 51 years. This total volume represents a lower boundary available for melting during eruptive events when lahars mudflows can be generated, because mainly in the winter, nearly 0.14 km3 w.eq.
