Fault Geometry Invariance and Differentiable Ensemble Solutions for Simultaneous Fault and Slip Inversion in Heterogeneous Crustal Structures

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Fault slip inversions based on geodetic observations deepen our understanding of earthquake source processes. Previous attempts to simultaneously estimate the fault geometry and slip distribution have typically assumed a homogeneous half‐space owing to the prohibitively high computational costs of conventional numerical approaches.

Coseismic damage runs deep in continental strike-slip faults

Earth and Planetary Science Letters, 2020
Abstract Coseismic off-fault damage and pulverization significantly influence the mechanical and transport properties, and in turn the rupture dynamics of faults. Although field-based, laboratory, and numerical studies help elucidate the structure of damage zones adjacent to modern strike-slip faults, the vertical extent of these zones remains an ...

Linking Interseismic Locking to Coseismic Rupture: The 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract We investigate interseismic locking on the Kamchatka megathrust, source of the 2025 Mw 8.8 earthquake, using a data‐driven probabilistic framework. Horizontal GNSS velocities constrain a boundary element model on a triangulated megathrust geometry, while an algorithmic sampling strategy estimates the locking probability for fault elements ...

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.

Earthquake rupture extents and coseismic slips promoted by damaged fault zones [PDF]

Journal of Geophysical Research: Solid Earth, 2016
AbstractHere we investigate the effects of damage fault zones on rupture propagation by conducting a series of 3‐D dynamic rupture simulations on a planar vertical strike‐slip fault. We find that damage fault zones can promote rupture extent and increase earthquake potency.

Refined Coseismic Slip and Afterslip Distributions of the 2021 Mw 6.1 Yangbi Earthquake Based on GNSS and InSAR Observations

Remote Sensing
On 21 May 2021, an Mw 6.1 earthquake occurred in Yangbi County, Dali Bai Autonomous Prefecture, Yunnan Province, with the epicenter located in an unmapped blind fault approximately 7 km west of the Weixi-Qiaohou fault (WQF) on the southeastern margin of ...

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.

Slip distribution of the February 6, 2023 Mw 7.8 and Mw 7.6, Kahramanmaraş, Turkey earthquake sequence in the East Anatolian Fault Zone

Seismica, 2023
On February 6, 2023, two large earthquakes occurred near the Turkish town of Kahramanmaraş. The moment magnitude (Mw) 7.8 mainshock ruptured a 310 km-long segment of the left-lateral East Anatolian Fault, propagating through multiple releasing step ...

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.

GPS observations of coseismic deformation following the 2016, August 24, Mw 6 Amatrice earthquake (central Italy): data, analysis and preliminary fault model

Annals of Geophysics, 2016
We used continuous Global Positioning System (GPS) measurements to infer the fault geometry and the amount of coseismic slip associated to the August 24, 2016 Mw 6 Amatrice earthquake.
