Introductionn. Similarly, body-wave seismologists have long been aware of the severe effect that velocity gradients and low-velocity zones can have on wave amplitudes. Awareness that such effects can completely swamp those of anelasticity has, undoubtedly, deterred many investigators from pursuing research on seismic-wave attenuation.

2-D Image of Seismic Attenuation beneath the Deep Seismic Sounding Profile “Quartz,” Russia SE direction, away from the Baltic Shield. Our model exhibits strong 2-D, vertical and horizontal attenuation contrasts. A high-attenuation layer in the depth range of 120–150 to 160–180 km can apparently be associated with the presence of a partial melts within the base of the lithosphere.

Frequency-dependent Attenuation of High-frequency , and , Waves in the Upper Crust in Western Nagano., respectively. The frequency dependence of the quality factor of . waves is very weak as compared with that of . waves. The ratio of ../.. is larger than unity in the entire analyzed frequency range.
