Unrest at the Laguna del Maule volcanic field 2005–2020: renewed acceleration of deformation
Autor: Kurt L. Feigl, Loreto Córdova, C. Cardona, H. Le Mével
Publikováno v: Bulletin of Volcanology. 83
The Laguna del Maule volcanic field in Chile has been exhibiting unrest since 2005. New GPS and InSAR data reveal a second episode of accelerated deformation beginning in late 2016 and continuing through May 2020, with an uplift rate > 290 mm/year be

International audience; ilicic systems generate the most explosive eruptions on Earth. In contrast to basaltic systems, they can accumulate large volumes of magma without systematically erupting, confronting the classical interpretation that a volcan

Rapid reinflation following the 2011-2012 rhyodacite eruption at Cordón Caulle volcano (Southern Andes) imaged by InSAR: Evidence for magma reservoir refill
Autor: Jonathan Lazo, Luis E. Lara, Daniel Basualto, Loreto Córdova, Francisco Delgado, Matthew E. Pritchard
Publikováno v: Geophysical Research Letters. 43:9552-9562
Cordon Caulle is a large fissural volcano that has erupted rhyodacitic magma of the same composition in its past three historical eruptions in 1921, 1960 and 2011-2012. There was significant ground deformation observed before and during the 2011-2012

Hydrothermal alteration and its effects on the magnetic properties of Los Pelambres, a large multistage porphyry copper deposit
Autor: Loreto Córdova, César Arriagada, Fernando Poblete, Joseline Tapia, Brian Townley
Publikováno v: Journal of Applied Geophysics. 132:125-136
The Los Pelambres porphyry copper deposit is located 190 km north of Santiago, Chile. A paleomagnetic and mineralogical study was conducted at this deposit to determine the effects of hydrothermal alteration on the magnetic properties and minerals of

Publikováno v: Science Advances
A warped paleoshoreline records 10,000 years of magma-driven surface deformation above an active rhyolite-producing reservoir.
Large rhyolitic volcanoes pose a hazard, yet the processes and signals foretelling an eruption are obscure. Satellite

Publikováno v: Geophysical Research Letters. 42:6590-6598
The Laguna del Maule (LdM) volcanic field in the southern volcanic zone of the Chilean Andes exhibits a large volume of rhyolitic material erupted during postglacial times (20–2 ka). Since 2007, LdM has experienced an unrest episode characterized b

Publikováno v: GSA Today. :4-10
Explosive eruptions of large-volume rhyolitic magma systems are common in the geologic record and pose a major potential threat to society. Unlike other natural hazards, such as earthquakes and tsunamis, a large rhyolitic volcano may provide warning
