Whole-rock, mineral, matrix glass and Fe-Ti oxide geochemistry of the 1937, 1994 and 2014 eruption products of Rabaul Caldera, Papua New Guinea

Melina Höhn, Brendan McCormick Kilbride, Margaret Hartley

This dataset comprises the complete geochemical data supporting Höhn et al. (Journal of Petrology) on the magma storage and evolution of Rabaul Caldera, Papua New Guinea. It includes whole-rock major and trace element compositions, electron probe microanalyses of plagioclase, clinopyroxene, orthopyroxene, olivine, …

Modelling magma storage and transport in Aira Caldera and Sakurajima Volcano, Japan.

Lorenzo Mantiloni, James Hickey, Rami Alshembari, Brendan McCormick Kilbride et autres

Sakurajima volcano, located on the rim of the Aira caldera in Japan, represents a major hazard for the heavily populated area of Kagoshima Bay. In recent decades, ground deformation modelling and seismic imaging have inferred the presence of a large magma reservoir …

From Crystal Mush to Eruptible Magma: Thermo-Poroelastic Controls on Melt Channelization

Rami Alshembari, James Hickey, Lorenzo Mantiloni, Brendan McCormick Kilbride

The generation of eruptible magma from long-lived, crystal-rich mush reservoirs remains a fundamental challenge in volcanology. Magma stored in the crust commonly resides as a high-crystallinity mush below the eruptibility threshold, yet many volcanoes exhibit frequent eruptions that require rapid remobilization of …

SO2 flux measurements from ground, air and space before, during and after a lava fountain on Mt Etna

Alexander Riddell, Mike Burton, Ben Esse, Brendan McCormick Kilbride et autres

Quantifying volcanic sulfur dioxide (SO2) emissions is essential for understanding magmatic processes and improving eruption forecasting. We present a four-day, multi-platform investigation of SO₂ emissions at Mt Etna, Italy, spanning 15–18th July 2024 and capturing the build-up, climax, and recovery from a …

Magmatic volatile budgets of the 2014 Tavurvur eruption at Rabaul Caldera, Papua New Guinea

Melina Höhn, Brendan McCormick Kilbride, Margaret Hartley, Mike Burton et autres

Rabaul is a caldera volcano on New Britain Island, Papua New Guinea, whose active cone Tavurvur ranks seventh globally for long-term SO2 and CO2 emissions. It is unknown why Rabaul is such a strong emitter of volcanic gases. Magma mixing between basaltic …

Petrological insights into magma storage and evolution at Rabaul Caldera, Papua New Guinea

Melina Höhn, Margaret Hartley, John B Dikaung, Ima Itikarai et autres

Rabaul is a caldera volcano in Papua New Guinea. Its most recent caldera-forming eruption occurred ~1400 years ago, with numerous intra-caldera eruptions since. Erupted whole rock compositions are commonly attributed to fractional crystallisation along a single liquid line of descent, but mafic …

Quantification of low-temperature gas emissions reveals CO 2 flux underestimates at Soufrière Hills volcano, Montserrat

Alexander Riddell, Mike Burton, Ben Esse, Brendan McCormick Kilbride et autres

We performed helicopter-borne optical MultiGAS measurements of volcanic gas emissions from Soufrière Hills Volcano, Montserrat, revealing distinct spikes in SO 2 and HCl concentrations within a larger CO 2 -rich plume. Acid-rich concentration spikes matched the distribution of high-temperature fumaroles, whereas CO …

Helium, carbon and nitrogen isotope evidence for slab influence on volcanic gas emissions at Rabaul caldera, Papua New Guinea

Brendan McCormick Kilbride, Peter H. Barry, Tobias P. Fischer, Greg Holland et autres

The chemical and isotopic composition of gases emitted by subduction zone volcanoes can provide insights into the origin of magmatic volatiles. In volcanic arcs, magmatic volatiles can be supplied from the mantle, the subducting slab, or the rocks of the arc crust. …

Petrographic and Geochemical Evidence for a Complex Magmatic Plumbing System beneath Bagana Volcano, Papua New Guinea

Joshua Brown, Iris Buisman, Maria Paula Castellanos Melendez, John B Dikaung et autres

Abstract Bagana is a persistently active stratovolcano located on Bougainville Island, Papua New Guinea. Characteristic activity consists of prolonged lava effusion over months to years, with occasional shifts to explosive vulcanian or sub Plinian eruptions that threaten surrounding communities. Satellite observations have …

Petrographic and geochemical investigation of magma reservoir processes at Rabaul Caldera, Papua New Guinea

Melina Hoehn, Brendan McCormick Kilbride, Margaret Hartley

Rabaul is a large caldera system located at the northeastern tip of the island of New Britain, Papua New Guinea. Historically, it has been the most active volcano in Papua New Guinea. Rabaul is capable of large volume, high intensity caldera-forming eruptions …

Poroelastic Deformation at Soufrière Hills: A New Perspective on Volcano Deformation Dynamics

Rami Alshembari, James Hickey, Karen Pascal, Lorenzo Mantiloni et autres

Volcano deformation studies often neglect the role of the porous, crystal-rich magma reservoirs in modulating surface deformation patterns. Our study examines the current deformation at Soufrière Hills Volcano (SHV) in its ongoing intra-eruptive unrest, with an emphasis on the influence of a …
