Deformation and seismicity near Sabancaya volcano, southern Peru, from 2002 to 2015
(American Geophysical Union, 2015-03-19)
We use interferometric synthetic aperture radar (InSAR) and local seismic data to investigate the cause of earthquake sequences near Sabancaya volcano in southern Peru from 2002 to 2014, with a particular focus on events ...
The 2013–2020 seismic activity at Sabancaya Volcano (Peru): Long lasting unrest and eruption
(Elsevier, 2023-03)
Sabancaya volcano is the youngest and second most active volcano in Peru. It is part of the Ampato-Sabancaya volcanic complex which sits to the south of the ancient Hualca Hualca volcano and several frequently active faults, ...
Source model for sabancaya volcano constrained by DInSAR and GNSS surface deformation observation
(Molecular Diversity Preservation International, 2020-06)
Sabancaya is the most active volcano of the Ampato-Sabancaya Volcanic Complex (ASVC) in southern Peru and has been erupting since 2016. The analysis of ascending and descending Sentinel-1 orbits (DInSAR) and Global Navigation ...
Actividad del volcán Sabancaya (Perú) 2016-2017: observaciones petrográficas y geoquímicas de los depósitos de tefras del 2017
(Presses universitaires Blaise PascalFR, 2018-04)
From 2013 to present-day, the Sabancaya volcano has resumed a new eruptive episode that we have subdivided in two phases: the first phase was characterized by degassing; coincided with the occurrence of five fumarolic vents ...
Evolution of eruptive process at Sabancaya Volcano (Perù) 2014- 2018
(Istituto Nazionale di Geofisica e VulcanologiaITA, 2018)
Sabancaya Volcano (5960 m) is a stratovolcano located approximately 80 km southeast of the city of Arequipa in southern Peru. In the Holocene, activity at Sabancaya has included several Plinian eruptions which were followed ...
Remote measurement of high preeruptive water vapor emissions at Sabancaya volcano by passive differential optical absorption spectroscopy
(American Geophysical UnionUS, 2017-05)
Water (H2O) is by far the most abundant volcanic volatile species and plays a predominant role in driving volcanic eruptions. However, numerous difficulties associated with making accurate measurements of water vapor in ...
Volcanic gas emissions and degassing dynamics at Ubinas and Sabancaya volcanoes; implications for the volatile budget of the central volcanic zone
(ElsevierNL, 2017-06)
Emission of volcanic gas is thought to be the dominant process by which volatiles transit from the deep earth to the atmosphere. Volcanic gas emissions, remain poorly constrained, and volcanoes of Peru are entirely absent ...
Source model for Sabancaya volcano constrained by DInSAR and GNSS surface deformation observation
(MDPI AGCH, 2020-06)
Sabancaya is the most active volcano of the Ampato-Sabancaya Volcanic Complex (ASVC) in southern Perú and has been erupting since 2016. The analysis of ascending and descending Sentinel-1 orbits (DInSAR) and Global Navigation ...
Petrological and geochemical constraints on the magmatic evolution at the Ampato-Sabancaya compound volcano (Peru)
(Elsevier, 2023-09-23)
In order to gain insights into continental arc magmatic processes, we have conducted a petrological and geochemical study of major and trace elements and Sr, Nd, and Pb isotopes of the Ampato-Sabancaya compound volcano, ...
Pre-eruptive magmatic processes associated with the 2016-2018 explosive activity of Sabancaya volcano (Perù)
(Istituto Nazionale di Geofisica e VulcanologiaITA, 2018)
Sabancaya volcano is one of the most active Central Andes Volcanoes. Historical records reveal an eruptive activity in 1750-1784 AD and more recently in 1990-1998 AD. The most recent eruptive activity of Sabancaya started ...
