DataSheet1_Crustal heterogeneity effects on coseismic deformation: numerical simulation of the 2008 MW 7.9 Wenchuan earthquake.docx

, 2023
Coseismic deformation of large earthquakes causes significant property damages and fatalities, which requires quantitative research of multiple disciplines such as geodesy, geological investigation, seismic tomography, and seismic dislocation theory. The

Northward rupture and early afterslip of two graben-bounding normal faults during the 2025 Dingri earthquake of Tibet

Communications Earth & Environment
The Mw 7.0 Dingri earthquake, the largest documented normal-faulting event in southern Tibet, struck within the NS-trending Dinggye-Xainza Rift system. Here we combine field observations, high resolution optical and synthetic aperture radar imagery and ...

Coseismic and Postseismic Deformations of the 2023 Turkey Earthquake Doublet

Remote Sensing
On 6 February 2023, an earthquake doublet of Mw 7.8 and Mw 7.5 occurred in southeastern Turkey and caused surface ruptures over 350 km for the eastern Anatolian fault (EAF) and 150 km for the Surgu fault (SF), respectively. Over 3700 Mw > 3.0 aftershocks

Decadal Creep Acceleration on the Northern Japan Trench Driven by Erosion of Heterogeneously Locked Asperities

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Geodetic and seismic observations before the 2011 Mw 9.0 Tohoku‐oki earthquake indicate decadal‐scale acceleration of aseismic slip along the northern Japan Trench, but the mechanism remains debated. We show that this transient can be explained by creep‐front propagation that progressively erodes heterogeneously locked asperities.

Multi‐Scale Growth of an Mw 7.0 Earthquake via Hierarchical Cascading Rupture From an Mw 3.8 Repeating Event

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract To understand what governs earthquake size, we investigated the 2021 Mw 7.0 Japan Trench earthquake, which began near a nest of repeating earthquakes. High‐precision hypocenter relocation and P‐waveform correlation show that the mainshock initiated nearly identically to Mw 3.8 repeaters.

Cessation of Nearby Low‐Frequency Earthquake Activity Following the December 2024 Mw 7.0 Mendocino Earthquake: The Likely Role of Pore Pressure Reductions

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Earthquakes affect surrounding fault systems through multiple mechanisms. Here, we examine a rare cessation of activity in 27 families of low‐frequency earthquakes (LFEs) that likely reflect fault creep at the southern edge of Cascadia subduction, near the Mendocino triple junction.

Bridge-Pier Caisson foundations subjected to normal and thrust faulting:physical experiments versus numerical analysis [PDF]

, 2015
Surface fault ruptures can inflict serious damage to engineering structures built on or near them. In the earthquakes of Kocaeli, Chi-chi, and Wenchuan a number of bridges were crossed by the emerging normal or thrust faults suffering various degrees of ...

Tectonic Landform and Lithologic Age Impact Uncertainties in Fault Displacement Hazard Models

Geophysical Research Letters
Tectonic landforms and surficial lithologic age are essential data for producing quality late Quaternary fault maps and predicting coseismic fault rupture location before an earthquake.

Shallow coseismic slip and downdip afterslip associated with the 2022 MW6.7 Menyuan (China) earthquake

Geodesy and Geodynamics
Investigating the spatial distribution of coseismic rupture, postseismic afterslip, and their interactions is essential for understanding the heterogeneous frictional characteristics of faults, and seismic hazard assessments.

An Innovative Approach for Estimating Coseismic Surface Uplifts Using Ionospheric Observations From Remote GNSS Stations: First Application for the 2025 Myanmar Earthquake

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The Mw 7.7 Myanmar earthquake on 28 March 2025 ruptured ∼480 km of the Sagaing Fault. Its fault slip distribution remains poorly constrained by three‐dimensional surface displacement data due to sparse GNSS‐coverage near the fault. Satellite‐based synthetic aperture radars capture meters of right‐lateral displacements but isolating vertical ...
