BAIES - Bayesian Inference of Earthquake Source parameters kinematic and dynamic finite fault models (GC18-06716J)

Proper understanding of geophysical processes controlling earthquake rupture propagation is a key point in earthquake hazard mitigation. Slip inversions provide the rupture, we will extend the models from finite source inversion...

Modeling source parameters of a large earthquakes (GP202/04/P056)

, which are important for detailed investigation of that region. Slip patches method willbe used for estimation of the source parameters, especially for a final slip. The low number of the searched parameters makes this inversio...

Inversion of focal mechanisms and seismic moment tensors for stress and its spatiotemporal variation (GA22-10747S)

by Vavryčuk (2014), who proposed an iterative procedure for a joint inversion for stress and fault orientations. The inversion is fast and robust and widely used in the geophysical community. Even though the Vavryčuk's inversio...

Constrained models of seismic source in between a double-couple and moment tensor (GAP210/12/2235)

in the inverse process, which may be additionally ill-conditioned due to inexact hypocenter or the inconsistent inverse problem. It seems reasonable to assume a simpler source model directly combination of a shear slip wit...

Using space geodesy to investigate the mechanics of earthquake ruptures (7AMB12GR006)

Static displacement measured with space geodesy methods (by the Global Navigation Satellite System), represents an important constraint on the inverse problem of the slip distribution on the faults, significantly complementing seism...

Reactions of slip dislocations with grain boundary observed by in situ TEM and their relation to slip band structure near grain boundary in bulk (IAA1010702)

Slip transmission through grain boundaries (GBs) has been studied in previous results and theoretical calculations indicated that the slip geometry is not the dominant factor. Stresses due to the slip bands formed in one gr...

Elementary processes of indirect slip transfer across grain boundaries and their influence on strength of materials (IAA100100638)

The aim is to determine processes at grain boundaries during slip transfer or slip generation, and to estimate their influence on the strength of materials. It has been supposed as yet that the slip transfer is controlled b...
