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.

b‐Values of Large Earthquake Sequences Depend on Their Mainshock Location

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We evaluate four hypotheses regarding b‐values in large earthquake sequences using the Japanese earthquake catalog: H1 ${\mathcal{H}}_{1}$: Around large earthquakes, b‐values vary more than expected at random. H2 ${\mathcal{H}}_{2}$: b‐values decrease prior to large earthquakes.

Linking Interseismic Locking to Coseismic Rupture: The 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We investigate interseismic locking on the Kamchatka megathrust, source of the 2025 Mw 8.8 earthquake, using a data‐driven probabilistic framework. Horizontal GNSS velocities constrain a boundary element model on a triangulated megathrust geometry, while an algorithmic sampling strategy estimates the locking probability for fault elements ...

Prototyping the Seismogenic Fault Injection Test (SFIT)

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract The treatment of induced seismicity risk would benefit from a small, standardized injection test that probes the seismic response to fluid injection—to optimally improve earthquake forecasts before a larger injection commences. To accomplish this goal, we propose a “model differencing” framework: this framework optimizes injection protocols by

Fault Geometrical Control on Fault Slip: Experimental Validation of Theoretical Models

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Slip distribution along tectonic faults is recognized as highly heterogeneous across all spatial scales and is linked to various aspects of the earthquake cycle, such as aftershock density and stress‐drop variability. A key factor often considered to control slip heterogeneity is the fault geometry, which is typically nonplanar at various ...
