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.

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.

Analytical models of volcanic ellipsoidal expansion sources

Annals of Geophysics, 2013
Modeling non-double-couple earthquakes and surficial deformation in volcanic and geothermal areas usually involves expansion sources. Given an ensemble of ellipsoidal or tensile expansion sources and double-couple ones, it is straightforward to obtain ...

From Magma to Atmosphere: Halogen Fluxes During Volcanic Eruptions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Volcanic eruptions release significant quantities of volatile elements into the atmosphere and stratosphere. Plinian eruptions are particularly efficient at dispersing these elements due to their large magma volumes and high eruption columns.

Analysis and quasistatic FE modeling of long period impulsive events associated with explosions at Stromboli volcano (Italy)

Annals of Geophysics, 1999
Broadband seismic measurements performed in 1995 and 1996 in the summit region of Stromboli are analyzed. The experiment in 1995 used an array of four Guralp seismometers and one Wielandt-Streckeisen seismometer.

The 2025 Mw 7.6 Aomori Megathrust Earthquake in Northeast Japan: Failure of a Structurally and Rheologically Bounded Asperity Beneath a Cold Mantle Wedge

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract To explore mechanisms of rupture segmentation, we invert coseismic GNSS offsets for the 2025 Mw 7.6 Aomori, Japan earthquake. Our preferred curved‐fault solution images a compact thrust rupture at 25–50 km depth with peak slip ∼2.5 m near 35 km.

A new consistent and high-precision earthquake catalogue for the Taupō Volcanic Zone, New Zealand

Seismica
The Taupō Volcanic Zone is a ~300 km long, volcanically active region in the North Island of Aotearoa New Zealand. As well as hosting numerous active volcanoes, it is also one of the most seismically active parts of the country.

Development of an early-warning system for monitoring remote volcanoes

Annals of Geophysics, 1996
Many andesitic volcanoes are quiescent for long time periods: usually (but not always) an increase in seismic activity and in deformation precedes an eruption by a few months or a few days.

High‐Resolution 3‐D Lithospheric Structure of the Subducting Carnegie Ridge and the Ecuadorian Margin Imaged From Teleseismic Receiver Functions

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The Ecuadorian margin is a forearc‐arc system shaped by oceanic terrane accretion and Carnegie Ridge subduction, yet the accretion mechanism and ridge subduction extent remain poorly constrained. Using teleseismic P‐wave receiver functions from dense seismic arrays, we image velocity discontinuities within the overriding plate and subducting ...
