Stress fields around magma chambers influenced by elastic thermo-mechanical deformation: implications for forecasting chamber failure
(2021)
Defining the conditions that lead to the rupture of a magma chamber is essential to forecast eruptions. So far, models simulating magma chamber dynamics have neglected the effects of elastic thermal expansion in the host ...
Numerical Modeling of Time-dependent Fluid Dynamics and Differentiation of a Shallow Basaltic Magma Chamber
(2010)
This contribution presents a numerical model of time-dependent
physical processes and differentiation in a cooling magma chamber
to obtain the magma and liquid composition and model the distribution
of minerals and H2O ...
Reconciling mechanical models of caldera ring-fault nucleation within the transcrustal magmatic system paradigm
(Elsevier B.V., 2024)
© 2024 Elsevier B.V.The formation of a collapse caldera requires the nucleation of circumferential ring-faults that connect an underlying magma chamber with the Earth's surface. The roof of the magma chamber collapses as ...
Magma Chamber Associated to Deep Faults in Copahue Active Volcanic Complex, South America, Suggested by Magnetotelluric Study
(National Academy of Sciences of Ukraine. Subbotin Institute of Geophysics, 2018-08)
Magnetotelluric studies were carried out in 1993 and 2008 inside the caldera of Copahue Volcanic Complex, located in South America, at the border between Chile and Argentina (37°45ʹ S; 71°10.2ʹ W). The main effusive centre ...
Volcanotectonics: the tectonics and physics of volcanoes and their eruption mechanics
(2022)
The physical processes that operate within, and beneath, a volcano control the frequency, duration, location and size of volcanic eruptions. Volcanotectonics focuses on such processes, combining techniques, data, and ideas ...
Multiple melt bodies fed the AD 2011 eruption of Puyehue-Cordón Caulle, Chile
(Nature Publishing Group, 2015-12)
Within the volcanological community there is a growing awareness that many large- to small-scale, point-source eruptive events can be fed by multiple melt bodies rather than from a single magma reservoir. In this study, ...
