Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.Abstract The diverse volcanic activity in the Alaska Peninsula section of the Alaska‐Aleutian subduction zone is presumably caused by substantial variations in mantle wedge melting or trans‐crustal processes beneath the arc. In this study, we investigate sub‐arc melting beneath the Alaska Peninsula by measuring P‐wave attenuation, as attenuation is ...

Thin‐plate modeling of interseismic deformation and asymmetry across the Altyn Tagh fault zone [PDF]
Geophysical Research Letters, 2008 Creeping dislocations in an elastic half‐space are commonly used to model interseismic deformation. However, this semi‐infinite conventional model can lead to biased inferences of the slip rate and the fault locking depth. We therefore favor the use of a thin‐plate model sheared at its base in agreement with the current knowledge of the seismogenic ...

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 ...

Interseismic Deformation and Earthquake Hazard along the Southernmost Longitudinal Valley Fault, Eastern Taiwan [PDF]
Bulletin of the Seismological Society of America, 2012 About half of the 8 cm/yr of oblique convergence across the active convergent plate boundaries of Taiwan occurs in eastern Taiwan, across the Longitudinal Valley. Significant shortening and left‐lateral slip occurs across the Longitudinal Valley fault there, both as shallow fault creep and as seismogenic fault slip.

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.

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.

Geophysical Research LettersUnraveling the surface deformation and fault kinematics during the seismic cycle is crucial for understanding earthquake physics. Herein, we use geodetic and seismic observations to quantify the interseismic coupling, coseismic rupture, and postseismic ...

Geodesy and GeodynamicsCentral Sumatra, Indonesia, is historically known for its significant seismic activities, most notably the devastating 1883 earthquake. In this study, we measured the interseismic deformation using continuous GNSS observation data for three years from ...

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

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.
