Spatiotemporal Distribution of Afterslip following the 2014 Yutian Mw 6.9 Earthquake Using COSMO-SkyMed and Sentinel-1 InSAR Data

open access: yesRemote Sensing, 2023
Spatiotemporal distribution of early afterslip is essential for seismic hazard evaluation and determination of fault friction properties. In this study, we used early post-seismic COSMO-SkyMed (19 February 2014–08 April 2014) and long-term Sentinel-1 (16

Co- and Post-seismic Deformation Mechanisms of the 2020 Mw6.0 Jiashi Earthquake in Xinjiang (China), Revealed by Sentinel-1 InSAR Observations

open access: yesFrontiers in Environmental Science, 2022
On 19 January 2020, an Mw6.0 earthquake occurred in Jiashi County, Xinjiang, China. This earthquake is a strong earthquake that occurred in the Kepingtage Belt.

Co-seismic internal deformations in a spherical layered earth model

open access: yesGeophysical Journal International, 2020
SUMMARYUsing a numerical integral method, we deduced a set of formulae for the co-seismic internal deformation in a spherically symmetric earth model, simultaneously taking self-gravitation, compressibility and realistically stratified structure of the Earth into account.

Internal co-seismic deformation and curvature effect based on an analytical approach [PDF]

open access: yesEarthquake Science, 2017
In this study, we present a new method to compute internal co-seismic deformations of a homogeneous sphere, based on our previous approach (Dong et al. 2016). In practical numerical computations, we consider a strike-slip point source as an example, and compute the vertical co-seismic displacement on different internal spherical surfaces (including the

Co- and post-seismic Deformation Mechanisms of the MW 7.3 Iran Earthquake (2017) Revealed by Sentinel-1 InSAR Observations

open access: yesRemote Sensing, 2019
The extraction of high-accuracy co- and post-seismic deformation fields and inversions of seismic slip distributions is significant in the comprehension of seismogenic mechanisms.

Identification of Surface Deformation in InSAR Using Machine Learning

open access: yesGeochemistry, Geophysics, Geosystems, 2021
The availability and frequency of synthetic aperture radar (SAR) imagery are rapidly increasing. This surge of data presents new opportunities to constrain surface deformation that spans various spatial and temporal scales. This expansion also introduces

Recent Crustal Deformation in West-Central South America [PDF]

open access: yes, 2003
I use interferometric synthetic aperture radar (InSAR) to create maps of crustal deformation along the coast and within the volcanic arc of central South America. I image deformation associated with six subduction zone earthquakes, four volcanic centers,

Preliminary study on co-seismic deformation steps of digital fixed-point and double earthquakes in Yunnan Province

open access: yes地震科学进展, 2020
The determination of the subsequent-earthquake trend is a hot topic for people in the disaster area. By analyzing the correlation between amplitudes of co-seismic deformation and subsequent earthquake from double earthquakes during 2008—2018 recorded by ...

Co‐seismic deformation of deep slabs based on summed CMT data [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2012
We assess the co‐seismic deformation inferred from earthquake moment tensor solutions for subducting slabs at depths greater than 50 km globally. We rotate each moment tensor into a local slab reference frame, then sum tensors within 50 km depth bins to approximate long term deformation characteristics.
