The Role of Tectonic Inheritance in Active Rift Seismicity and Magmatism: Constraints From 3‐D Gravity Inversion and D‐InSAR Modeling of the 2025 Fentale Swarm, Ethiopia

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The role of inherited lithospheric structures in active rift seismicity and magma intrusion remains a key uncertainty in continental breakup dynamics. We investigate the January 2025 Northern Main Ethiopian Rift swarm using constrained 3‐D gravity inversion and D‐InSAR observations to characterize crustal architecture, seismicity, and active ...

Gas Measurements Reveal Fractional Degassing and Water Interaction During a Flank Eruption of Pacaya Volcano (Guatemala)

open access: yesGeophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract SO2 flux and gas composition were measured during the 2021 flank eruption of Pacaya Volcano (Guatemala). The SO2 flux, measured with Tropomi, gradually rose from ∼2 to ∼30 kg/s over a 5 month period before the eruption. Field UV camera data showed that >95% of the SO2 was emitted from the summit crater.

Historic Unrest of the Campi Flegrei Caldera, Italy

open access: yes, 2022
After some centuries of subsidence, following the AD 1538 Monte Nuovo last eruption, the Campi Flegrei caldera has shown unrest episodes since at least 1950.

Patterns of Evolutionary Diversification in a World‐Significant Hotspot of Salmonid Diversity: A Study of Landlocked Salvelinus Fish of the Kronotskoe‐Uzon Area, Kamchatka

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We have examined the phylogenetic relationships, genomic structure, admixture, and historical gene flow among the endemic charrs from the Kronotskoe‐Uzon water system in Kamchatka, in order to reconstruct their evolutionary history. We found that this unique diversity formed in the post‐LGM—Holocene time as a result of several waves of Salvelinus malma

Genomic Insights Into the Body Size Evolution in Felidae (Mammalia: Carnivora)

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study performed reannotation of the genomes of two felid species and conducted the first genomic analysis of body size variation and evolution in Felidae. Our results demonstrate that felid body size evolution is driven by adaptive changes in both core signaling pathways and individual key genes.

The incrementally zoned Miocene Ayagaures ignimbrite (Gran Canaria, Canary Islands) [PDF]

open access: yes, 2010
The 20–25 m thick trachyphonolitic Ayagaures ignimbrite cooling unit [(AY); 11.8 Ma] exposed over 250 km2 (onshore volume ca. 4.5 km3 DRE) is the uppermost and most voluminous cooling unit of the Middle Fataga Formation (MFF), part of the Fataga Group ...

Invasive mammals disrupt sea–land nutrient inputs over 169 years on subtropical oceanic islands

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract Invasive mammals have severely impacted oceanic islands, reducing or extirpating seabird populations and driving the collapse of nutrient flows with lasting ecosystem effects. We investigated these dynamics on contrasting subtropical oceanic islands in the South Pacific: Rangitāhua, a large island where goats, cats, and rats caused the ...

The Campi Flegrei caldera (Italy)

open access: yes, 2022
S.361-374To date, the origin of the Campi Flegrei caldera is still under debate and may be related to (1) a single caldera collapse associated with the Neapolitan Yellow Tuff (NYT) eruption, (2) two subsequent caldera collapses associated with the NYT ...
