Canadá Nº 1470. Lima 41. San Borja, Lima - Perú [email protected] [email protected] Keywords: Geothermal map, Eje Volcánico Sur, contribute in the development of this environmentally geothermal manifestations, volcanic rocks, deep faults, friendly resource, for electric power generation and direct Perú. uses ABSTRACT 1. INTRODUCTION The Andes Cordillera resulted from the interaction of the All over the world the major geothermal potential is Nazca Plate and the South American Plate. The subduction associated to discontinuous chains of Pio-Pleistocenic process occurring between both plates has controlled all volcanic centers that take part of the Pacific Fire Belt, and geological evolution of such territory since Mesozoic to Perú as a part of this, has a vast geothermal manifestation present time. In this context, magmatic and tectonic like hot springs, geysers, fumaroles etc. processes have allowed the development of geothermal environments with great resources to be evaluated and The Peruvian Geological Survey - INGEMMET- has subsequently developed making a sustainable exploitation traditionally been the first institution devoted to perform of them. geothermal studies that include the first mineral resources and thermal spring’s inventory. The first geothermal studies In consequence, Perú has a vast geothermal potential with were accomplished in the 70's starting with the first many manifestations at the surface as hot springs, geysers, inventory of mineral and thermal springs (Zapata, 1973). fumaroles, steam, etc., all over the country. The first The main purpose of those studies was the geochemical geothermal studies began in the 70's with the first inventory characterization of geothermal flows. -

Tracing a Major Crustal Domain Boundary Based on the Geochemistry of Minor Volcanic Centres in Southern Peru
7th International Symposium on Andean Geodynamics (ISAG 2008, Nice), Extended Abstracts: 298-301 Tracing a major crustal domain boundary based on the geochemistry of minor volcanic centres in southern Peru Mirian Mamani1, Gerhard Wörner2, & Jean-Claude Thouret3 1 Georg-August University, Goldschmidstr. 1, 37077 Göttingen, Germany ([email protected], [email protected]) 2 Université Blaise Pascal, Clermont Ferrand, France ([email protected]) KEYWORDS : minor volcanic centres, crust, tectonic erosion, Central Andes, isotopes Introduction Geochemical studies of Tertiary to Recent magmatism in the Central Volcanic Zone have mainly focused on large stratovolcanoes. This is because mafic minor volcanic centres and related flows that formed during a single eruption are relatively rare and occur in locally clusters (e.g. Andagua/Humbo fields in S. Peru, Delacour et al., 2007; Negrillar field in N. Chile, Deruelle 1982) or in the back arc region (Davidson and de Silva, 1992). These studies showed that the "monogenetic" lavas are high-K calc-alkaline and their major, trace, and rare elements, as well as Sr-, Nd- and Pb- isotopes data display a range comparable to those of the Central Volcanic Zone composite volcanoes (Delacour et al., 2007). It has been argued that the eruptive products of these minor centers bypass the large magma chamber systems below Andean stratovolcanoes and thus may represent magmas that were derived from a deeper level in the crust (Davidson and de Silva, 1992; Ruprecht and Wörner, 2007). This study represents a continuation of our work to understand the regional variation in erupted magma composition in the Central Andes (Mamani et al., 2008; Wörner et al., 1992). -

JUSTIFICACIÓN En el territorio nacional existen alrededor de 400 volcanes, la mayoría de ellos no presentan actividad. Los volcanes activos se encuentran hacia el sur del país en las regiones de Arequipa, Moquegua y Tacna, en parte de la zona volcánica de los Andes (ZVA), estos son: Coropuna, Valle de Andagua, Hualca Hualca, Sabancaya, Ampato, Misti en la Región Arequipa; Ubinas, Ticsani y Huaynaputina en la región Moquegua, y el Yucamani y Casiri en la región Tacna. El Volcán Ubinas es considerado el volcán más activo que tiene el Perú. Desde el año 1550, se han registrado 24 erupciones aprox. (Rivera, 2010). Estos eventos se presentan como emisiones intensas de gases y ceniza precedidos, en algunas oportunidades, de fuertes explosiones. Los registros históricos señalan que el Volcán Ubinas ha presentado un Índice máximo de Explosividad Volcánica (IEV) (Newhall & Self, 1982) de 3, considerado como moderado a grande. -

The analysis of ascending and descending Sentinel-1 orbits (DInSAR) and Global Navigation Satellite System (GNSS) datasets from 2014 to 2019 imaged a radially symmetric inflating area, uplifting at a rate of 35 to 50 mm/yr and centered 5 km north of Sabancaya. The DInSAR and GNSS data were modeled independently. We inverted the DInSAR data to infer the location, depth, and volume change of the deformation source. -
Frozen Mummies from Andean Mountaintop Shrines: Bioarchaeology and Ethnohistory of Inca Human Sacrifice
Hindawi Publishing Corporation BioMed Research International Volume 2015, Article ID 439428, 12 pages http://dx.doi.org/10.1155/2015/439428 Review Article Frozen Mummies from Andean Mountaintop Shrines: Bioarchaeology and Ethnohistory of Inca Human Sacrifice Maria Constanza Ceruti Instituto de Investigaciones de Alta Montana,˜ Universidad Catolica´ de Salta, Campus Castanares,˜ 4400 Salta, Argentina Correspondence should be addressed to Maria Constanza Ceruti; [email protected] Received 22 December 2014; Accepted 5 April 2015 Academic Editor: Andreas G. Nerlich Copyright © 2015 Maria Constanza Ceruti. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. This study will focus on frozen mummies of sacrificial victims from mounts Llullaillaco (6739 m), Quehuar (6130 m), ElToro (6160 m), and the Aconcagua massif. These finds provide bioarchaeological data from mountaintop sites that has been recovered in scientifically controlled excavations in the northwest of Argentina, which was once part of the southern province of the Inca Empire. Numerous interdisciplinary studies have been conducted on the Llullaillaco mummies, including radiological evaluations by conventional X-rays and CT scans, which provided information about condition and pathology of the bones and internal organ, as well as dental studies oriented to the estimation of the ages of the three children at the time of death. Ancient DNA studies and hair analysis were also performed in cooperation with the George Mason University, the University of Bradford, and the Laboratory of Biological Anthropology at the University of Copenhagen. Ethnohistorical sources reveal interesting aspects related to the commemorative, expiatory, propitiatory, and dedicatory aspects of human sacrifice performed under Inca rule. -

Climbing Pichu Pichu
Climbing Pichu Pichu Day 1: Arequipa - Laguna de Salinas We leave Arequipa at 8am in a private vehicle. We drive 3 hours to the Laguna de Salinas perched at 4300m high. This lagoon is a natural habitat for a very special wildlife: flamingos. We will also see llamas, alpacas and vicunas. During a good part of the year, the lagoon is actually a salar. The scenery is so spectacular, it's like in Bolivia, especially as the lagoon is surrounded by the majestic Misti volcano (5825m), Pichu Pichu (5664) and also Ubinas volcano (5672m) which is the most active one in Peru. Eruptions guaranteed! But no worries, that's safe for us ... We camp at 4400m near aguas calientes (hot springs) and will enjoy a great sunset! Day 2: Pichu Pichu - Arequipa Today, we'll wake up early and head to the "Pichu Pichu Basecamp" located at about 4700m. Today is Ascension Day! We'll have 900m of ascent, about 5-6 hours round trip. You will be rewarded for your efforts once arrived at the top. The stunning view of Arequipa and volcanoes Misti and Chachani, but also over the lagoon (salar) and Ubinas volcano. The descent is great, you can jump and slide on the steep hills of Pichu Pichu! We will finally get some time to rest on our way back to Arequipa in 4x4. Approximate arrival time: 5pm. This adventure is for you! Price per person, based on a tour for at least 2 persons Included: -Experienced guide -Tents, mattresses, cooking equipment, etc. -Pick up and drop off to your hotel and transport to and from the base of the mountain -All meals while trekking (one each of lunch, dinner and breakfast) Please note that you have to carry the equipement by yourself. -
