The size of local and regional earthquakes in the former Soviet Union (USSR) has been
given by the energy class (K-class) system since the late 1950s. K-class was originally …

Envelopes of scalar waves are simulated at various distances from an instant point source
embedded in a random uniformly scattering medium by means of direct Monte-Carlo …

The well-known decrease of scattering capability of the Earth medium with increasing depth
is parametrized as a power-law decay of turbidity, or scattering coefficient. The single …

Using the single backscattering model a seismic quality factor (QC), a frequency parameter
