Along‐Strike Coupling Heterogeneity in Cascadia's Slow‐Slip Zone Constrained by GNSS and Reduced‐Order Rate‐And‐State Friction Modeling

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Slow slip events (SSEs) in the Cascadia subduction zone exhibit along‐strike segmentation, where the central segment has longer recurrence intervals but smaller moments. We quantify the controls on this variability by combining geodetic inter‐SSE coupling inversion with Bayesian inference of a quasi‐dynamic rate‐and‐state friction SSE‐cycle ...

The 2025 Kamchatka Earthquake and Tsunami: Cascading Impacts and Risks to Japan

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2837-2854, September 2026.
ABSTRACT On July 29th, 2025, a large earthquake (Mw 8.8) occurred near the Kamchatka Peninsula. This event caused a tsunami that reached Japan's Pacific coast, even though the source was far away. In this study, we analyze the characteristics of earthquakes and tsunamis and discuss how they relate to the recurrence possibility and risk in Japan.

Multi‐Hazard Shaking‐Tsunami Fatality Risk Estimation for Coastal Communities

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2618-2633, September 2026.
ABSTRACT This study develops a multi‐hazard fatality risk model for a coastal community (Tofino) on Vancouver Island, Canada, subjected to earthquake‐tsunami threats from the Cascadia subduction megathrust events. The model incorporates variable population distributions and uncertain fatality rate models, in addition to other key model components, such

Deformation Patterns and Rupture Mechanisms of the Longitudinal Valley Fault in Eastern Taiwan: Insights From Three‐Dimensional Discrete Element Modeling

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Active faults exhibit complex geometric features, with rupture processes controlled by the coupled effects of tectonic loading, fault geometry, and internal displacement heterogeneity. To elucidate the interrelationship between long‐term deformation, stress redistribution, and rupture evolution, we constructed a three‐dimensional numerical ...

Mechanisms of Transient Postseismic Deformation Following the 2024 Mw 7.5 Noto Peninsula Earthquake Inferred From Horizontal and Vertical GNSS Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The 2024 Mw 7.5 Noto Peninsula earthquake provided an opportunity to investigate postseismic deformation in a tectonically complex back‐arc region in central Japan, where Miocene normal faults are reactivated under present‐day compression.

Liquefaction-induced large-scale ground deformation triggered by the 7 January 2025 MS 6.8 Dingri earthquake: characteristics and formation mechanisms

Dizhi lixue xuebao
Objective  In liquefaction-susceptible geological settings, the spatial superimposition of earthquake-induced liquefaction and coseismic fault rupture renders the genetic attribution of surface deformation highly ambiguous, yet systematic field ...

Detection of Interannual and Fine‐Scale Plate Coupling Variations Using Intraplate Earthquakes and Geodetic Data: Application to the Tohoku‐Oki Plate Boundary

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We propose a method to infer detailed spatiotemporal variations in interplate coupling by integrating geodetic and seismic data. It examines whether focal mechanisms of intraplate earthquakes occurring near the plate interface align with the stressing rates caused by a geodetically derived slip‐deficit rate model, evaluating deviations from a ...

Coseismic Displacement Accumulation Between 1996 and 2019 Using A Global Empirical Law on Indonesia Continuously Operating Reference Station (InaCORS)

Journal of Geospatial Information Science and Engineering, 2019
Indonesia archipelago is one of the most populated country with active and complex tectonic zone in the world. Plate boundaries were assembled by four major plate which made the region not only vulnerable to earth-hazard but also prone to semi-dynamic ...

Vector Angular Continuity in the Fusion of Coseismic Deformations at Multiple Optical Correlation Scales

Sensors, 2023
As one of the common techniques for measuring coseismic deformations, optical image correlation techniques are capable of overcoming the drawbacks of inadequate coherence and phase blurring which can occur in radar interferometry, as well as the problem ...
