At high frequencies f the spectrum of S-wave accelerations is characterized by a trend of
exponential decay, e− πkf. In our study, the spectral decay parameter k shows little variation …

The structure of the earth has been extensively studied using seismic waves generated by
natural earthquakes and man-made sources. In classical seismology, the earth is …

Seismic Wave Propagation in Stratified Media presents a systematic treatment of the
interaction of seismic waves with Earth structure. The theoretical development is physically …

A new global model of radial variations in intrinsic shear and compressional attenuation, Qμ
(r) and Qκ (r), is presented. The model, called QL6, is derived from recent observations of …

Resolving anelastic attenuation, its spatial and depth variations, can provide important
constraints on the composition and dynamics of the earth. However, measuring Q is difficult …

The dislocation microstructure of mantle materials can account simultaneously for long-term
steady-state creep, and for stress wave attenuation at seismic frequencies. The hypothesis …

Body wave, surface wave, and normal mode data are used to place constraints on the
frequency dependence of Q in the mantle. With a simple absorption band model it is …

Data from the Anza array in southern California have been analyzed to study attenuation.
The data set includes records from 68 earthquakes, each of which recorded at an average of …

Seismic waves have long been known to attenuate at a rate greater than that predicted by
geometric spreading of their wave fronts. Knopoff (1964) pointed out more than four decades …

An effective solution to the problem of the detection and identification of low‐yield coupled
and fully decoupled underground nuclear explosions appears available via use of high …
