Preparation of updated volcanic hazards map for el Misti volcano, Peru
(International Association of Volcanology and Chemistry of the Earth's InteriorPE, 2006)
The city centre of Arequipa -second largest city in Peru (about one million people)- is located 17 km away from Misti Volcano (5822 a.s.l.) and about 3.5 km vertically below it. During the last 50,000 years, vulcanian and ...
Probing the hidden magmatic evolution of El Misti volcano (Peru) with the Pb isotope composition of fumaroles
(Springer, 2022-01-20)
This work proposes a new method to probe the hidden magmatic evolution of quiescent Andean volcanoes from the Pb isotope composition of gases. The method is based on an assimilation-fractional crystallisation-degassing ...
Geochemical survey of hot springs around Ubinas, the most historical active volcano in southern Peru
(International Association of Volcanology and Chemistry of the Earth's InteriorPE, 2006)
Ubinas (5675 m a.s.l.) is known as the most active volcano in southern Peru during historical times, with 23 minor eruptive or intense fumarolic crises since 1550. Due to its intense explosive recurrence and to the high ...
Seismic monitoring of 2006 Ubinas volcano eruption
(EGU General Assembly, 2007)
At the end of March 2006, Ubinas volcano (16.355º S, 70.903º W, 5672 m) considered the most active volcano of Peru during the last 450 years begun a new eruption process which is lasting until present. The Geophysical ...
Field guides for excursions to the nevado del ruiz volcano and to the romeral fault system (colombia), in the frame of the neotectonics of arc-continent collision concepts
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2011)
Central Cordillera of Colombia near to the Nevado del Ruiz volcano, is a seismically active area above the subducting slab of the Nazca plate and deforming upper crust of the Andes. Buildings in the region require strengthening ...
Temporal evolution of long-lived magmatic systems: the Chachani volcano complex, south of Perù
(Istituto Nazionale di Geofisica e VulcanologiaITA, 2018)
The Chachani Volcanic Complex (CVC) is an extensive (~289±10 km3) assemblage of spatially, temporally and genetically related major and minor eruptive centers. The c. 1.2 Myr-long activity suggests that the CVC is a ...
Valley of volcanoes in Andahua, geopark in southern Peru project
(Instituto Geológico, Minero y Metalúrgico - INGEMMETESP, 2010)
The Instituto Geológico Minero y Metalúrgico – INGEMMET has developing studies in areas of geological significance to promote the establishment of Geoparks. Some of these areas stand out for their geodiversity and volcanic ...
Poás volcano: Geophysical-Geochemical signatures and dynamics of its magmatic-hydrothermal system
(International Association of Volcanology and Chemistry of the Earth's Interior, 2014-09)
Poás volcanic complex hosts a hyper-acid lake where geochemical signatures are related to two major controlling processes: (a) The level of inux and dissolution-hydrolysis of magmatic volatiles in a sub-surface hydrothermal ...
