- •
Crucial features of seismograms and spectra with small amplitudes are explained by fractional calculus.
- •
Precursors and followers of coherent waves are captures by fractional wave equations.

A novel fractional Green's function implies primary and secondary wave crests not depending on fractality.
- •
A modified Huygen's principle is used and stochastic aspects are discussed.
