A Feasibility Study of an FEM Simulation Used in Co-Seismic Deformations: A Case Study of a Dip-Slip Fault

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2013
For this study, we conducted a numerical simulation on co-seismic displacement for a dip-slip fault in a half-space medium based upon a finite element method (FEM).

Seismological and Ground Deformation Study of the Ionian Islands (W. Greece) during 2014–2018, a Period of Intense Seismic Activity

open access: yesApplied Sciences, 2022
Seismicity in the Ionian Sea (W. Greece) is mainly generated along the Cephalonia–Lefkada Transform Fault Zone (CLTFZ) in the central Ionian, and on the northwestern termination of the Hellenic subduction margin in the south.

Post-seismic relaxation process and vertical deformation following the 2008 Ms8.0 Wenchuan earthquake, China

open access: yesGeodesy and Geodynamics, 2012
The post-seismic horizontal and vertical deformations following the 2008 Ms8.0 Wenchuan earthquake are inferred from GPS and precise leveling data. The post-seismic relaxation process is measured using CPS data from campaign stations located around the ...

The effects of earthquakes with different rupture patterns in the main Himalayan thrust on deformation and stress changes in the Himalayan orogenic belt and Southern Tibetan Plateau

open access: yesGeomatics, Natural Hazards & Risk
The relationships between co-seismic slip and surface deformation under different rupture patterns along the Main Himalayan Thrust remain poorly understood.

Seismic Cycle in Bituminous Dolostones (Monte Camicia Thrust Zone, Central Apennines, Italy)

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Seismic ruptures often propagate along fault zones cutting km‐thick sequences of carbonates (e.g., Wenchuan Mw 7.8, 2008, China; L’Aquila Mw 6.1, 2009, Italy).

Effect of Kunlun Ms 8.1 earthquake on crustal deformation in northeastern edge region of Qinghal-Tibet plateau

open access: yesGeodesy and Geodynamics, 2010
Seismic fault parameters can be inversed with Okada model based on deformation data before and after earthquakes in focal region and its adjacent area. Co-seismic displacements can be simulated by using these parameters, and then regional velocity field ...

Co-seismic deformation for the 2015 MW7.8 Gorkha earthquake (Nepal) using near-field GPS data

open access: yesGeodesy and Geodynamics, 2023
Seasonal variations and common mode errors affect the precision of the Global Positioning System (GPS) time series. In this paper, we explore to improve the precision of coordinate time series, thereby providing a better detection of weak or transient ...

Seismogenic characteristics of the 2025 Dingri Ms 6.8 earthquake: Insights from GNSS observations

open access: yesEarthquake Research Advances
This study investigates the seismogenic characteristics of the 2025 Dingri MS 6.8 earthquake through multi-parametric GNSS analyses of velocity field, strain rate evolution and displacement patterns across pre-seismic and co-seismic phases.

Land Surface Temperature Variation Following the 2017 Mw 7.3 Iran Earthquake

open access: yesRemote Sensing, 2019
During an earthquake, crustal deformation, fluid flow, and temperature variation are coupled; however, earthquake-related land surface temperature (LST) variations remain unclear. To determine whether post-seismic fluid migration can cause changes in LST,
