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.

The 2025 Mw 7.6 Aomori Megathrust Earthquake in Northeast Japan: Failure of a Structurally and Rheologically Bounded Asperity Beneath a Cold Mantle Wedge

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract To explore mechanisms of rupture segmentation, we invert coseismic GNSS offsets for the 2025 Mw 7.6 Aomori, Japan earthquake. Our preferred curved‐fault solution images a compact thrust rupture at 25–50 km depth with peak slip ∼2.5 m near 35 km.

Transient Creep on the Yarlung Zangbo Suture in Southern Tibet Triggered by the 2015 Gorkha (Nepal) Earthquake

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Large earthquakes often elevate seismicity in surrounding regions, as seen on the Xainza‐Dinggyê rift in southern Tibet after the 2015 MW 7.8 Gorkha (Nepal) earthquake. In contrast, the EW‐trending Yarlung Zangbo suture (YZS), located directly north of this event, exhibits seismic quiescence.

Evolution of Coupled Seismic‐Aseismic Slip During the 2025 Mw 6.8 Sanriku‐Oki, Japan, Megathrust Sequence

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract On 9 November 2025, a Mw 6.8 Sanriku‐Oki earthquake struck a Japan Trench segment with inferred recurrent aseismic slip and Mw ∼7 earthquakes. Using S‐net seafloor data, we examine the preparatory and post‐mainshock evolution of this foreshock–mainshock–aftershock sequence.

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

Cascading Rupture of a Conjugate Oblique Faulting Rift in the 2025 Dingri Southern Tibetan Plateau Earthquake: A Typical Slow‐to‐Fast Process

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract The 2025 Mw7.1 Dingri earthquake is the largest normal‐faulting event in southern Tibetan plateau recorded with near‐field observations. By integrating back‐projection imaging, multi‐point‐source inversion, and finite‐fault modeling, we reveal that the rupture propagated at variable speeds in a cascading manner across a complex conjugate fault

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 ...

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,

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 ...

Assessing the Yuli surface deformation from the 20220918 Chishang earthquake: an integrated RTK GNSS network approach

Terrestrial, Atmospheric and Oceanic Sciences, 2023
The 20220918 Chishang earthquake impacted the Yuli area in the Longitudinal Valley of eastern Taiwan. Longitudinal Valley is situated near the boundary of the Philippine Plate and Eurasian Plate boundary with frequent seismicity and historical ...
