La explotación de azufre del volcán Overo
(Universidad Nacional de Cuyo. Facultad de Filosofía y Letras. Instituto de Geografía, 1957)
Advanced signal recognition methods applied to seismo-volcanic events from Planchon Peteroa Volcanic Complex: deep neural network classifier
Advanced techniques in the recognition and classification of seismo-volcanic events are transcendental when studying active volcanoes, not only for their importance as an accurate real time seismic monitoring procedure but ...
Fossilised geothermal surface features of the Whitianga Volcanic Centre (Miocene), Coromandel Volcanic Zone, New Zealand: Controls and characteristics
(Elsevier Science, 2019-09)
The Late Miocene Whitianga Volcanic Centre of the Coromandel Volcanic Zone, North Island, New Zealand, is host to 18 known, siliceous and intensely silicified deposits including: silicified volcanics; sediments of inferred ...
First portable scanning-DOAS system developed in Latin America for volcanic SO2 monitoring
(Pergamon-Elsevier Science Ltd, 2021-06)
Due to the extreme conditions in volcanic environments, in-situ sampling of gases is considered a very dangerous task. For this reason, the implementation of new remote sensing techniques and instruments has become a ...
Centros volcánicos del Domuyo y Payún Matru
(Universidad Nacional de Cuyo. Facultad de Filosofía y Letras. Instituto de Geografía, 1948)
Volcanic ash from Puyehue-Cordón Caulle Volcanic Complex and Calbuco promote a differential response of pro-inflammatory and oxidative stress mediators on human conjunctival epithelial cells
(Academic Press Inc Elsevier Science, 2018-11)
Volcanic ash could pose a hazard to the ocular surface as it is constantly exposed to environmental particles. We exposed conjunctival cells to Puyehue-Cordón Caulle volcanic complex (PCCVC) or Calbuco ash particles and ...
Geochronology of the late Pliocene to recent volcanic activity in the Payenia back-arc volcanic province, Mendoza Argentina
(Pergamon-Elsevier Science Ltd, 2012-08)
Eighteen samples originating from monogenetic cones and larger complexes in the back-arc Payenia volcanic province, in Mendoza Argentina, have been dated by the 40Ar/ 39Ar method. Groundmass and plagioclase separates give ...
Volcanic unrest at Nevados de Chillán (Southern Andean Volcanic Zone) from January 2019 to November 2020, imaged by DInSAR
(Elsevier Science, 2022-07)
The volcanic complex of Nevados de Chillan, ´ located in the Southern Volcanic Zone (SVZ) of the Andes, has been active for the past 640 ± 20 ka. Its volcanic activity includes dome forming eruptions, explosive events, and ...
Unusual volcanic instability and sector collapse configuration at Chimpa volcano, central Andes
(Elsevier Science, 2020-02)
Upper Miocene Chimpa volcano is one of the largest stratovolcanoes of the back–arc region of the central Andes. The gentle–sloped volcano underwent previously unrecognized volcanic instability, consisting of ≈ 2 km3 mass– ...
The lifecycle of volcanic ash: advances and ongoing challenges
Explosive volcanic eruptions can produce vast amounts of volcanic ash made up mainly of fragments of magmatic glass, country rock and minerals<2 mm in size. Ash particles forming from magma fragmentation are generated by ...
