Measuring Coseismic Deformation With Spaceborne Synthetic Aperture Radar: A Review [PDF]

, 2019
In the past 25 years, space-borne Synthetic Aperture Radar imagery has become an increasingly available data source for the study of crustal deformation associated with moderate to large earthquakes (M > 4.0).

Deformation Features of Coseismic Surface Rupture

, 2017
The term coseismic surface rupture is defined as a surface fracture produced by a current or large historic earthquake. The term is interchangeable with surface earthquake fault and earthquake fault in Japan, which is enhanced for the topographic morphology and geometry of surface fractures formed during large earthquakes [Research Group for Active ...

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.

Evolution of Coupled Seismic‐Aseismic Slip During the 2025 Mw 6.8 Sanriku‐Oki, Japan, Megathrust Sequence

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract On 9 November 2025, a Mw 6.8 Sanriku‐Oki earthquake struck a Japan Trench segment with inferred recurrent aseismic slip and Mw ∼7 earthquakes. Using S‐net seafloor data, we examine the preparatory and post‐mainshock evolution of this foreshock–mainshock–aftershock sequence.

Coherent shift estimation for stacks of SAR images [PDF]

, 2011
Speckle tracking is used with SAR images to estimate displacements, in ways that support or integrate interferometric measurements. This paper derives Fisher information expressions for the displacement estimation using coherent speckle tracking, for the

A Transient in Surface Motions Dominated by Deep Afterslip Subsequent to a Shallow Supershear Earthquake: The 2018 Mw7.5 Palu Case

Geochemistry, Geophysics, Geosystems, 2021
The 2018 Mw7.5 Palu earthquake is a remarkable strike‐slip event due to its nature as a shallow supershear fault rupture across several segments and a destructive tsunami that followed coseismic deformation. GPS offsets in the wake of the 2018 earthquake

Cascading Rupture of a Conjugate Oblique Faulting Rift in the 2025 Dingri Southern Tibetan Plateau Earthquake: A Typical Slow‐to‐Fast Process

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

Coseismic and Postseismic Crustal Deformation Associated With the 2016 Kumamoto Earthquake Sequence Revealed by PALSAR-2 Pixel Tracking and InSAR [PDF]

, 2020
Coseismic and postseismic crustal deformations caused by earthquake episodes are important in understanding the mechanisms of these episodes as well as the fault rheology near an epicentral area.

Coseismic surface rupture and seismogenic background of the 1951 M 8.0 Beng Co earthquake in the central Tibetan Plateau

Dizhi lixue xuebao
Objective  The coseismic surface rupture formed by an earthquake is the most obvious geomorphological evidence of fault activity. Its spatial distribution and deformation characteristics record essential information about seismic ruptures and fault ...
