Along‐Strike Variations in Sub‐Arc Melting Beneath the Alaska Peninsula Revealed by P‐Wave Attenuation

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 ...

Interseismic Fault Coupling and Slip Rate Deficit on the Central and Southern Segments of the Tanlu Fault Zone Based on Anhui CORS Measurements

Remote Sensing, 2022
The Tanlu fault zone, extending over 2400 km from South China to Russia, is one of the most conspicuous tectonic elements in eastern Asia. In this study, we processed the Global Positioning System (GPS) measurements of Anhui Continuously Operating ...

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 ...

Goce derived geoid changes before the Pisagua 2014 earthquake

Geodesy and Geodynamics, 2018
The analysis of space – time surface deformation during earthquakes reveals the variable state of stress that occurs at deep crustal levels, and this information can be used to better understand the seismic cycle.

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.

Quantifying slip balance in the earthquake cycle: Coseismic slip model constrained by interseismic coupling [PDF]

Journal of Geophysical Research: Solid Earth, 2015
AbstractThe long‐term slip on faults has to follow, on average, the plate motion, while slip deficit is accumulated over shorter timescales (e.g., between the large earthquakes). Accumulated slip deficits eventually have to be released by earthquakes and aseismic processes.

Improving resolution model of probable asperity distribution along southern Sumatra Subduction Zone using denser GPS stations

Geomatica
The southern Sumatra Subduction Zone (SSZ) is point outed as an area with seismic potential due to plate tectonic movement. To observe seismic activity in this region, Global Positioning System (GPS) networks can be used to monitor tectonic plate ...

On the mechanical behaviour of a low-angle normal fault: the Alto Tiberina fault (Northern Apennines, Italy) system case study [PDF]

Solid Earth, 2016
Geological and seismological observations have been used to parameterize 2-D numerical elastic models to simulate the interseismic deformation of a complex extensional fault system located in the Northern Apennines (Italy).

20th to 21st Century Relative Sea and Land Level Changes in Northern California

Tektonika, 2023
Sea-level changes are modulated in coastal northern California by land-level changes due to the earthquake cycle along the Cascadia subduction zone, the San Andreas plate boundary fault system, and crustal faults.
