Download Copahue Volcano (Active Volcanoes of the World) PDF

This booklet presents a finished description of the volcanological, petrological and geochemical good points of the Copahue volcano, positioned on the border among Argentina and Chile. medical experiences are restricted for this volcanic approach, because of its distant situation and hard entry in wintry weather. even if, Copahue is without doubt one of the so much lively volcanic structures within the southern Andes. tracking the volcano's task is of utter significance, because it offers technique of lifestyles for the within reach village of an analogous identify, web hosting the world's highest-located hot-springs lodge.

This book's goal is to provide the present tracking actions, and to explain destiny learn courses which are deliberate that allows you to mitigate volcanic dangers. specific consciousness is hence dedicated to the social and commercial actions just about the volcano, similar to future health remedies and geothermal power exploitation.

In a different part, the Copahue volcano is gifted as a terrestrial smooth analog for early-Earth and Mars environments.

2009), but in this case it is characterised by a different kinematics. The system is affecting Copahue volcano (Fig. 4a), where the summit vents and craters are aligned along a N60–70 ° E-striking trend. More specifically, in the summit Fig. L. Bonali et al. area a dike strikes N60 °E (Fig. 7f, g). The southern rim of the summit crater lake (Fig. 7b) is affected by N55 °E-striking fractures, showing a left-step en-echelon arrangement. Following the same trend, on the NE flank of Copahue volcano numerous eruptive fissures are present, with a N65 °E–N78 °E-striking orientation.

In addition, two dikes belonging to the same trend were recognized, which were intruded into a fault plane along the southern wall of the Caviahue caldera, close to the Pucón Mahuida pass. They strike N47 °E–N52 °E, with a left-stepping en-echélon arrangement. One of these dikes is aphyric and 2-m-thick, the second is porphyritic and 4-m-thick, with abundant phenocrysts of plagioclase, pyroxene and olivine (Fig. 7f, g). The kinematics of CVFS is transtensive, characterized by metric extensional fault scarps that border an ENE-WSW striking graben (Fig.

2009). Regarding neotectonic activity along this structure, several authors noticed that: (i) some reverse scarps, a few metres high, affect a glacial surface, together with open cracks (Folguera and Ramos 2000; Folguera et al. 2004); (ii) the southernmost of these reverse faults (defined as the “Copahue Fault” by Rojas Vera et al. 2009, cfr. 5 and Fig. 3) marks the main topographic break, thrusting ignimbrites over Quaternary till-like deposits near the Copahue village (Melnick et al. 2006); (iii) Rojas Vera et al.
