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

open access: yesGeophysical 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.

Slip distributions on active normal faults measured from LiDAR and field mapping of geomorphic offsets: an example from L'Aquila, Italy, and implications for modelling seismic moment release [PDF]

open access: yes, 2014
Surface slip distributions for an active normal fault in central Italy have been measured using terrestrial laser scanning (TLS), in order to assess the impact of changes in fault orientation and kinematics when modelling subsurface slip distributions ...

Coseismic surface deformation analyses using SAR and optical images: 2023 Kahramanmaraş earthquake sequence, Türkiye

open access: yesTurkish Journal of Earth Sciences
The 2023 Kahramanmaraş earthquake sequence in Türkiye, including Mw 7.7 and 7.6 mainshocks, caused significant surface ruptures along the East Anatolian Fault (EAF) and Sürgü–Çardak Fault (SCF). We calculated the coseismic displacement fields through pixel offset tracking (POT) analysis of Sentinel-1 SAR data and optical image correlation (OIC ...

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

open access: yesGeophysical 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

open access: yesGeophysical 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.

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

open access: yesGeophysical 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 ...

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

open access: yesCommunications 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 DEFORMATION OF 2011 MW 9 TOHOKU EARTHQUAKE - A NONLINEAR INVERSION OF GPS DATA

open access: yes, 2017
On March 11, 2011, a magnitude Mw = 9.0 megathrust occurred off the Tohoku coast near the Japan trench. This thesis studies the coseismic and postseismic deformation of the earthquake based on the Global Positioning System (GPS) observations.

Near-Fault Tilted Deformation of Buildings Associated with Coseismic Surface Ruptures in the Shenxigou Section, 2008 Mw 7.9 Wenchuan Earthquake, Eastern Tibet [PDF]

open access: yes
The coseismic surface ruptures associated with large earthquakes contribute to severe damage to near-fault buildings through fault deformation. However, previous studies simplified geological conditions and were based mainly on numerical and physical ...
