Coseismic dislocation modeling by physical experiments

, 2013
Detecting coseismic surface deformation provides useful information about geometry and kinematic of the seismo- genic fault activated during an earthquake. Recent advances in inversion of geodetic data (e.g.

A 3D finite-element mesh for modeling large-scale surface deformation induced by subduction megathrust earthquakes: Application to Chile

Seismica
Megaearthquakes (Mw > 8) cause continental-scale, long-lasting surface deformation, mainly due to viscoelastic relaxation of the asthenosphere. To investigate the links between this deformation and the slip history along subduction interfaces—including ...

Coseismic Surface deformation and Coulomb Static Failure Stresses change Modeling of 2024 Mw 7 Uqturpan earthquake, China

Abstract Knowledge of the earthquakes along the active tectonic structure is fundamental to comprehend the mechanics of continental plates margins and to approximate the earthquake potential in tectonic settings of area of interest. On 22nd January, 2024, an earthquake with magnitude Mw 7 struck in the area located 136 km west of Aksu, China ...
