Does Three‐Dimensional Structure Affect Tsunami Excitation and Stress Drop Estimates?—The Case of the 2011 Tohoku Earthquake

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Reliable calculations of coseismic sea‐surface deformation and stress drop are essential for understanding megathrust earthquake rupture and tsunami behavior. However, the impacts of realistic three‐dimensional (3D) structure, such as seafloor topography and structural heterogeneity, on stress‐change calculations and tsunami excitation during ...

Effects of Pore Fluid Properties on Dynamic Slip in Sandstone‐Derived Fault Gouges From the Groningen Gas Reservoir

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The dynamic slip behavior of faults is strongly influenced by the thermal and hydraulic properties of pore fluids, which control thermal pressurization (TP) during seismic slip. While previous experiments showed significant TP‐induced weakening in DI‐water‐saturated Groningen sandstone gouges, in situ fluids are brine or brine–gas mixtures ...

A physics-based integrated sem-newmark model for regional-scale coseismic landslide assessment [PDF]

, 2019
Coseismic landslides are one of the most catastrophic effects of earthquakes. Realistic prediction of coseismic landslides is crucial for the design of key infrastructure and to protect human lives in seismically active regions.

Site effects and widespread susceptibility to permanent coseismic deformation in the Avezzano town (Fucino basin, Central Italy): Constraints from detailed geological study [PDF]

, 2020
The Quaternary Fucino basin in the central Apennines of Italy was struck by one of the strongest Italian earthquakes of the last millennium (1915, Mw 7.0). The Avezzano town, ~ 9.0 km away from the epicentre, was completely destroyed.

Fifty Years of Shore Platform Erosion Monitoring at Kaikōura Peninsula, South Island, Aotearoa‐New Zealand

Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
Fifty years of micro‐erosion metre monitoring at Kaikōura show that the 2016 earthquake more than doubled shore platform erosion rates, transforming intertidal shore platforms into rapidly degrading supratidal marine terraces and reorganising the process and lithological controls that govern rock coast evolution.

Strategic Micro‐Awards Train the Next Generation and Grow a Cross‐Disciplinary Scientific Community: The AGeS Program Example

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Strategic micro‐grant programs have tremendous scientific and educational value. Such programs are cost‐effective and can be leveraged to support student training and incentivize new cross‐disciplinary science. Over the last 12 years, the AGeS (Advancing Geochronology Science, Spaces, and Systems) initiative developed three proposal‐driven ...
