Project

Seismic waves and sources in anisotropic media II (IAA300120801)

Seismic anisotropy is an overall property of the Earth's crust and upper mantle, which significantly complicates seismic wavefields and which is often neglected in modelling of seismic waves and in moment tenso...

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

Moment tensor is a general dipole source, but for practice it may be too general, its generality causing troubles during its reconstruction from noisy data of depleted sensor configuration when the moment tensor fa...
