Bayesian Inference of Complex Stress Evolution in Rate‐and‐State Governed Faults Constrained by Seismicity Rate Observations

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Temporal changes in seismicity rates can be conceptually understood as a response and consequence of stress changes. Dieterich (1994, https://doi.org/10.1029/93JB02581) formalized this relationship using empirically derived rate‐and‐state friction laws, and Heimisson and Segall (2018, https://doi.org/10.1029/2018JB015656) later generalized the

A Transient Coastal Uplift Event Revealed by Pleistocene Marine Terraces Along the 2015 M8.3 Illapel Earthquake Rupture, Chile

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Uplifted Pleistocene marine terraces in the Illapel area along the forearc of central Chile record spatially and temporally variable uplift rates on glacial‐cycle timescales. However, the underlying mechanisms for this uplift variability and its potential relationship with the megathrust‐earthquake cycle remain poorly understood.

Integration of Field Observations With Forward and Inverse Modeling for Tsunami Reconstructions Along the Fjord‐Dominated Coastlines of Northern Cascadia

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract Forward and inverse modeling techniques are often applied to paleotsunamis to reconstruct inundation parameters. The accuracy of both types of models can be influenced by geomorphology, particularly in areas such as northern Cascadia, where rocky headlands and fjords influence tsunami flow and the preservation of sedimentary deposits ...

Source Parameters of the 1906 Manas (Mw 7.7), 1944 Xinyuan (Mw 7.2) and 1812 Nilke Earthquakes and Seismotectonics of the Borohoro Shan, Western China

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The 1906 Manas Earthquake is the largest earthquake recorded in the Borohoro Shan (BRS) since 1900. The reported magnitude ranges from 7.2 to 8.3, but uncertainties remain regarding its size, mechanism, and responsible fault. Similar confusion exists for the 1812 Nilke and 1944 Xinyuan Earthquakes, the only other Mw > 7 earthquakes in the NE ...

Coseismic effects of the 2016 Amatrice seismic sequence: first geological results

Annals of Geophysics, 2016
Since the beginning of the ongoing Amatrice seismic sequence on August 24, 2016, initiated by a Mw 6.0 normal faulting earthquake, the EMERGEO Working Group (an INGV team devoted to earthquake aftermath geological survey) set off to investigate any ...

Coseismic Landslide Mapping Based on Trans-UNet and Transfer Learning

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Coseismic landslides often cause significant property damage and loss of life, necessitating timely and accurate detection for emergency response and hazard mitigation. Optical remote sensing imagery plays a critical role in landslide identification; however, sufficient high-resolution images might not be accessible after an earthquake.
