Depth of Magma Storage Under Iceland Controlled by Magma Fluxes [PDF]
Geochemistry, Geophysics, Geosystems, 2023 The compositions of volcanic materials are sensitive to physical conditions in the underlying magmatic system. When basaltic melts are saturated in olivine‐plagioclase‐augite prior to eruption, their compositions can be used to estimate the pressure at ...

Magma storage in a strike-slip caldera [PDF]
Nature Communications, 2016 The Ilopango caldera, El Salvador has had a number of large explosive eruptions, but its magmatic plumbing system is unclear. Here, Saxby et al. image a strike-slip faulted low-density structure under the caldera and interpret it as a gas-charged ...

Stress pinch points from glacial loading modulate magma ascent and storage in continental arcs [PDF]
Nature CommunicationsGrowing evidence indicates that glacial cycles influence volcanic activity, yet the physical mechanisms linking glaciation to magmatic processes in continental arcs remain unclear.

Carbonate-capped seamount subduction accelerates CO2-rich arc magma ascent [PDF]
Nature CommunicationsSubduction transports carbon into Earth’s interior, yet how subducted carbon influences arc magma ascent dynamics remains unclear. Here we combine volatile compositions of olivine-hosted melt inclusions with olivine diffusion chronometry at Pagan volcano

Frontiers in Earth Science, 2021 A key issue on active volcanoes is to investigate the position and characteristics of the magma reservoirs over time. The aim is to better understand the crustal magma transfer, therefore also to define the volcanic hazard and plan the mitigation ...

Geophysical Monograph Series, Page 435-447., 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.

Earth, Planets and Space, 2023 We investigated magma storage conditions prior to the 2011 and 2018 eruptions at Kirishima Shinmoe-dake volcano in Japan based on the relationship between geodetic volume change of magma chamber and erupted magma volume.

Deep Magma Transport Control on the Size and Evolution of Explosive Volcanic Eruptions
Frontiers in Earth Science, 2021 Explosive eruptions are the surface manifestation of dynamics that involve transfer of magma from the underground regions of magma accumulation. Evidence of the involvement of compositionally different magmas from different reservoirs is continuously ...
