Environmental Impact of Silicic Magmatism in Large Igneous Province Events
Geophysical Monograph Series, Page 133-151., 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.

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract Cloud condensation nuclei (CCN) modulate the properties and thus the climate effects of clouds. The North African dust plume is an important source of CCN in the North Atlantic trade‐wind zone. Yet, research into the nature and sources of these CCN is sparse, making it difficult to fully assess related cloud effects. Using combined airborne in

Deep Origin and Shallow Launch for the Etna 122 B.C. Mafic Plinian Eruption
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract Basaltic Plinian eruptions challenge our understanding of explosive volcanism. The 122 B.C. Plinian eruption of Etna ranks among the most powerful mafic explosive events known. Here, we combine volatile barometry of 122 B.C. from olivine‐hosted melt and fluid inclusions with comparative data from the sub‐Plinian Fall Stratified eruption at ...

Tectonics, Volume 45, Issue 5, May 2026.Abstract Southern Italy and eastern Sicily have been the site of several destructive historical earthquakes. Here at the junction between the western edge of the Calabrian subduction zone and the Malta Escarpment several strike‐slip faults have been mapped, which may be the surface expression of the lateral slab tear fault and are candidate sources for

Volcanism at Piton de la Fournaise as an Analog for Chloris Mons, Venus
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Identifying and investigating terrestrial analogs for Venus volcanic activity is necessary to prepare for the planned upcoming missions to Venus. We propose volcanism at Piton de la Fournaise, a frequently active oceanic shield volcano, as an analog to volcanism at Chloris Mons, Venus.

Application of Data Assimilation Methods to Reconstruct the 3–5 December 2015 Etna Eruption
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract The assessment of volcanic hazards is crucial to develop effective emergency plans, especially for volcanoes close to urban areas or under air traffic routes. Impact assessment for expected scenarios relies on underlying numerical models that require eruption source parameters as inputs, and forecasts drastically depend on their robust ...

Estimation of CO2 Emissions in Fault Systems at a Global Scale
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.Abstract Influenced by tectonic, geophysical, and environmental aspects, the release of carbon dioxide (CO2) in fault systems is a fundamental component of Earth's carbon cycle. Appreciating their contribution to natural greenhouse gas flow depends on knowing these emissions.

Modeling the Deformation Response to Mt. Etna Sliding Flank
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract The southeastern flank of Mt. Etna volcano slides into the Ionian Sea at rates of centimeters per year. While gravitational spreading and tectonic forces can cause volcanic flank collapse, their effects intrinsically trade off with magmatic forcing. There is still strong uncertainty regarding the processes underlying the sliding.

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract Observations of ground deformation provide insights on the triggering mechanisms of eruptions. At Aniakchak Crater (Aleutians) InSAR measured ∼ ${\sim} $72 cm of uplift in less than 7 months between 2022 and 2023. The uplift can be explained by the inflation of a point pressure source at a depth of 3.2 km.
