In seismology, the Kolsky Q models are mathematical Q models developed by Herbert Kolsky to describe how seismic waves lose energy and change speed as they travel through the Earth, widely used in seismic data processing. The basic Kolsky model, introduced in Kolsky’s 1963 book Stress Waves in Solids, is favored for its simplicity but doesn’t fully meet key physics standards, such as the minimum phase criterion or the Kramers-Kronig relations. The modified Kolsky model, later detailed in Yong-Xiong Wang’s 2008 book Seismic Inverse Q Filtering, improves accuracy by better representing velocity dispersion within seismic frequency ranges. These models help geophysicists analyze subsurface properties by measuring the Q factor.
