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

, 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.

Seismic and Aseismic Slip of the 2020 Mw 7.4 Oaxaca, Mexico, Earthquake: Implications for the Kinematic Characteristics and Frictional Behaviors in the Mexican Subduction Zone

, 2021
The coseismic surface deformation caused by the 2020 Oaxaca earthquake and postseismic deformation are described in Tang et al. paper “Geodetic Constraints on Modeling of Coseismic Slip and Postseismic Afterslip of the 2020 Mw 7.4 Oaxaca Earthquake ...

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 ...

Surface ruptures and off-fault deformation of the October 2016 central Italy earthquakes from DInSAR data

Scientific Reports, 2022
Large magnitude earthquakes produce complex surface deformations, which are typically mapped by field geologists within the months following the mainshock. We present detailed maps of the surface deformation pattern produced by the M.

Mechanical Decoupling Across the Deep Megathrust Boundary

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract We examine stress and strength across the deep subduction plate boundary at ∼60 km depth offshore northeastern Japan, near the downdip seismic limit of the megathrust. High‐frequency (2–5 Hz) moment tensor inversion of ∼2,000 M 2–3.5 earthquakes, integrated with existing catalogs, increases the number of focal mechanisms by more than a factor ...

Excess strain in the Echigo plain sedimentary basin, NE Japan: Evidence from coseismic deformation of the 2011 Tohoku-oki earthquake [PDF]

, 2016
Coseismic deformation depends on both the source fault and on the elastic properties of the crust. Large coseismic deformation associated with the 2011 Mw 9.0 Tohoku-oki earthquake enabled us to investigate strain anomalies from crustal inhomogeneity ...

Subsurface Deformation and Recovery From the Ridgecrest Mw 7.1 Earthquake Revealed by P‐Wave Velocity Time‐Lapse Tomography

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract We investigate co‐ and post‐seismic P‐wave velocity (Vp) changes following the July 2019 Mw 7.1 Ridgecrest strike‐slip earthquake using time‐lapse tomography from 50,345 P‐wave arrivals (2011–2024). Co‐seismically, Vp changes correspond to the volumetric strain change lobes of the earthquake, increasing in compressional zones and decreasing in

Coseismic Tectonic Surface Deformation during the 2010 Maule, Chile, M _w 8.8 Earthquake

Earthquake Spectra, 2012
Tectonic deformation from the 2010 Maule (Chile) M w 8.8 earthquake included both uplift and subsidence along about 470 km of the central Chilean coast. In the south, deformation included as much as 3 m of uplift of the Arauco Peninsula, which produced emergent marine platforms and affected ...

Factors influencing the effectiveness of SM-VCE method in solving 3D surface deformation

Geodesy and Geodynamics
The recovery of coseismic 3-dimensional (3D) surface deformation field plays a crucial role in studying seismic source characteristics and earthquake hazards. As of now, there are two main types of methods for recovering coseismic 3D surface deformations:

Triggered slip on multifaults after the 2018 Mw 6.4 Hualien earthquake by continuous GPS and InSAR measurements

Terrestrial, Atmospheric and Oceanic Sciences, 2019
On 6 February 2018 at 23:50 local time, a Mw 6.4 earthquake struck eastern Taiwan. We characterize the instantaneous surface ground motion and the permanent displacement induced by this event from continuous GPS data and SAR images within a short time ...
