Anisotropy of seismic waves in the uppermost part of the Earth crust (KJB3046301)

Project aims to develop techniques for using shear waves in shallow seismic surveys, mostly for determination of rock anisotropy in-situ. Converted shear waves will be used. This will allow usage of simple and cheap sources...

Seismic waves in inhomogeneous weakly anisotropic media (GA16-05237S)

Seismic anisotropy, mostly weak, is an omnipresent property of the Earth’s interior. Although weak, it influences seismic wave propagation considerably, especially S-wave propagation. It also affects the applicabil...
