Reevaluating Large‐Scale Deformation Precursors of Great Subduction Earthquakes: Insights From Satellite Gravity and GNSS Data

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Validating the controversial hypothesis that precursory gravity changes arise from sudden acceleration of subducting plates potentially triggering great earthquakes is of paramount importance. To rigorously evaluate proposed precursors for the 2011 Mw 9.0 Tohoku and 2010 Mw 8.8 Maule earthquakes, we develop a statistical framework that enables

Velocity changes after the 2021 MS 6.4 Yangbi earthquake based on passive image interferometry

Frontiers in Earth Science, 2023
An MS 6.4 earthquake occurred in Yangbi, Yunan Province, China, on 21 May 2021. The epicenter was on the blind branch fault in the west of the Weixi–Qiaohou–Weishan fault, but no surface rupture was obvious.

Variations in dv/v Susceptibility to Earthquake Shaking Along the Alaska Subduction Zone

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Earthquake‐triggered decreases in relative seismic velocity (dv/v) of the crust have been reported for many events, but regional variations in dv/v susceptibility to shaking are not well understood. Here, 14 Alaskan earthquakes with Mw 6.8–8.2 are consistently analyzed with single‐station coda‐wave interferometry.

Differentiated Rift Rupture and Apparent Northward Earthquake Ordering in Southern Tibet Revealed by the 2025 Mw 7.0 Dingri Earthquake and Its Preceding Events

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract North–south‐trending rifts in southern Tibet accommodate active east–west extension, but how normal‐faulting rupture varies with rift development remains unclear. Here we use Synthetic Aperture Radar observations to investigate the 2025 Mw 7.0 Dingri earthquake in the southern Xainza–Dinggye rift.

Fluid‐Controlled Tidal Modulation of Aftershocks Following the 2022 M6.8 Luding Earthquake

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Aftershock sequences record how fault zones recover and weaken after earthquakes, but the roles of fluid migration and stress heterogeneity remain difficult to isolate. Earth tides impose predictable stress perturbations and thus provide a natural probe of faults near failure, although their signals are often obscured by aftershock clustering.

Coseismic surface rupture during the 2018 Mw 7.5 Palu earthquake, Sulawesi Island, Indonesia

, 2020
Sulawesi Island is located at the triple junction between the converging Australian, Sunda, and Philippine plates. The magnitude (Mw) 7.5 Palu earthquake occurred on 28 September 2018 on Sulawesi Island and caused serious casualties.

Reappraisal and Analysis of Macroseismic Data for Seismotectonic Purposes: The Strong Earthquakes of Southern Calabria, Italy

Geosciences, 2023
In tectonically active areas, such as the Italian peninsula, studying the faults responsible for strong earthquakes is often challenging, especially when the earthquakes occurred in historical times. In such cases, geoscientists need to integrate all the

Shallow Slip Deficit: An Intrinsic Property of Continental Earthquakes, Slightly Enhanced by Fault Maturity

Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract A depletion of earthquake slip in the shallow crust (shallow coseismic slip deficit, or coseismic SSD) has been observed on <30, Mw ≥ 6 continental earthquakes, and attributed to the immaturity of the ruptured faults. We question the factors that contribute to the coseismic SSD.

Do Shallow Slip Deficits Reflect Fault Structural Maturity or Modeling Choices? A Comparative Analysis of Tibetan Strike‐Slip Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract InSAR‐constrained finite fault slip models are often used to characterize fault geometries and slip distributions of large continental earthquakes. A common feature of these models is a decrease in slip near the surface, commonly expressed as a percentage shallow slip deficit (SSD).

The May 2012 Emilia (Italy) earthquakes: preliminary interpretations on the seismogenic source and the origin of the coseismic ground effects

Annals of Geophysics, 2012
On May 20, 2012, a Ml 5.9 earthquake (T1) occurred in the Emilia-Romagna Region of northern Italy. This was preceded by a Ml 4.1 foreshock on May 19, 2012, and followed by several aftershocks, including two Ml 5.1 events, both on the same day. On May 29,
