From Fault Ruptures to Atmospheric Perturbations: Examining the 2016 Norcia Seismic Sequence
Earth and Space Science, Volume 13, Issue 11, November 2026.Abstract This study investigates lithosphere–atmosphere interactions during the 2016 Central Italy seismic sequence, providing the first systematic analysis of atmospheric impacts across the entire series within a complex tectonic setting. The static displacement fields of the main events were modeled using the Okada formulation and validated against ...

Annals of Geophysics, 1998 Time variations in the spatial distribution of earthquake epicentres are analyzed by application of the fractal correlation dimension method. The zone under investigation is located in Central Italy, bounded in longitude by 12.0 and 14.4 degrees east and

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.Abstract 2D finite deformation analysis commonly relies on simplified assumptions such as plane strain and isovolume, which are insufficient to fully characterize 3D geological structures, leading to incomplete tectonic interpretations. To overcome these limitations, this study proposes the Mohr‐cyclide for finite deformation as a new kinematic tool to

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.Abstract Physics‐based models of the earthquake cycle could be used for time‐dependent hazard assessment. For such an application, their parameters must be calibrated so that simulated earthquake sequences reproduce the statistics of past earthquakes, including recurrence statistics and magnitudes. This is challenging because the dynamics are described

Mechanical Decoupling Across the Deep Megathrust Boundary
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.Abstract We examine stress and strength across the deep subduction plate boundary at ∼60 km depth offshore northeastern Japan, near the downdip seismic limit of the megathrust. High‐frequency (2–5 Hz) moment tensor inversion of ∼2,000 M 2–3.5 earthquakes, integrated with existing catalogs, increases the number of focal mechanisms by more than a factor ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.Abstract Fluid‐rock interactions have major implications on the frictional behavior of fault rocks. Infiltration of CO2‐bearing fluids in ultramafic fault zones causes the progressive formation of serpentinite, talc‐magnesite (soapstone) and quartz‐magnesite (listvenite) assemblages.

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract We investigate co‐ and post‐seismic P‐wave velocity (Vp) changes following the July 2019 Mw 7.1 Ridgecrest strike‐slip earthquake using time‐lapse tomography from 50,345 P‐wave arrivals (2011–2024). Co‐seismically, Vp changes correspond to the volumetric strain change lobes of the earthquake, increasing in compressional zones and decreasing in
