Time scales and temperatures of crystal storage in magma reservoirs: implications for magma reservoir dynamics. [PDF]
Philos Trans A Math Phys Eng Sci, 2019 The thermal and therefore physical state of magma bodies within the crust controls the processes and time scales required to mobilize magmas before eruptions, which in turn are critical to hazard assessment. Crystal records can be used to reconstruct magma reservoir histories, and the resulting time and length scales are converging with ...

Stress and Strain in Magma‐Mush Reservoirs: Implications for Reservoir Failure and Magma Propagation [PDF]
Journal of Geophysical Research: Solid EarthAbstract Investigating the mechanical stability and failure of magma reservoirs following magma supply is critical for volcanic hazard assessment. While magma reservoirs were traditionally modeled as melt‐filled cavities, they are now more often described as crystal mushes where melt flows and is stored in porous networks.

Growth and thermal maturation of the Toba magma reservoir. [PDF]
Proc Natl Acad Sci U S A, 2021 Significance Understanding the thermal state of magma reservoirs before supereruptions is crucial for interpreting the processes leading to such catastrophic events. Here, we show that the two supereruptions of Toba were preceded and followed by protracted magma influx at relatively constant average volumetric rate over the past 2.2 ...

Numerical modelling of magma reservoir processes [PDF]
, 2022 For many years, volcanic and igneous processes were explained by the storage of magma in a melt-rich magma body, where chemical differentiation is controlled by fractional crystallisation. However, this idea for the storage and chemical differentiation of magma in the Earth’s crust has been challenged by data from natural magmatic systems.

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Exsolved volatiles in magma reservoirs [PDF]
Journal of Volcanology and Geothermal Research, 2018 We review our understanding of the exsolved volatile phase co-existing with magmas during pre-eruptive storage at the pressures and temperatures corresponding to crustal magma reservoirs. We explore the consequences and implications of such a volatile phase for magma and ore body petrogenesis and the fluid dynamics of magma reservoirs.

Determining the current size and state of subvolcanic magma reservoirs [PDF]
Nature Communications, 2020 AbstractDetermining the state of magma reservoirs is essential to mitigate volcanic hazards. However, geophysical methods lack the spatial resolution to quantify the volume of eruptible magma present in the system, and the study of the eruptive history of a volcano does not constrain the current state of the magma reservoir.

Magma Fizz: Tremor During the Kīlauea Summit Reservoir Decompression
Journal of Volcanology and Geothermal ResearchTypical eruptions at Kīlauea volcano involve the evacuation of magma from the summit and/or south caldera reservoirs towards the East or Southwest rift zones. The reservoir drainage provokes the summit deflation, and on extreme occasions, such as in 2018, the summit caldera collapse.
