Stardust Mine: A 2024 gabbroic shergottite from Arizona, USA

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1826-1846, August 2026.
Abstract This study provides an initial characterization of Stardust Mine, a fresh gabbroic enriched shergottite collected in Arizona, USA, in September 2024 and is the first Martian meteorite to be unequivocably collected on US soil. Analysis was conducted on the type specimen and finds that Stardust Mine is composed of equal proportions of pyroxene ...

Seismic Risk of Critical Transport Systems: Sensitivity Analysis of the Campania Railway Network to Bradyseism's Features

Risk Analysis, Volume 46, Issue 8, August 2026.
ABSTRACT This study examines the impact of epistemic uncertainties on the seismic risk of a critical transport system, the Campania railway network, during the ongoing bradyseismic unrest at Campi Flegrei, south of Italy. Seismic risk is quantified as the length of the railway requiring post‐event inspection, an operational proxy for service disruption.

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, Volume 73, Issue 5, Page 1331-1351, August 2026.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

Investigating Meter‐Scale Wavefield Complexity and Amplification at the Basin Edge With a Fiber‐Optic Array

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Edges of sedimentary basins generate complex seismic wavefield effects and localized amplification. Characterizing these effects and incorporating them into hazard models is difficult because tomographic models are often smooth and wavefield observations are often aliased.

Insights Into Magmatic Degassing, Hydrothermal Dynamics, and Eruption Precursors From Long Term SO2 Emission Monitoring at Whakaari/White Island, New Zealand

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Long‐term SO2 emission rate time series are critical for deciphering the subsurface processes regulating open‐vent volcanoes, yet extracting cyclical drivers from continuous degassing records remains challenging. We analyze a 14‐year (2006–2020) SO2 emission rate data set from Whakaari/White Island, New Zealand, identifying five chronological ...
