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 …

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 …

The seismological properties of the Earth's inner core have become of particular interest as
we understand more about its composition and thermal state,. Observations of anisotropy …

I analyze nearly 2000 handpicked differential times of core‐penetrating compressional
waves to image lateral variations in the anisotropic structure of the solid inner core. The …

Seismological studies indicate that the inner core of Earth is anisotropic for compressional
waves (P waves), and has low shear wave (S wave) velocity, and high seismic attenuation …

The seismological exploration of the Earth's inner core has revealed unexpected and
puzzling structural complexities. Its elastic anisotropy is now well established, and has been …

We collect a global data set of PKIKP and PKiKP phases recorded by the Global Seismic
Network and many regional seismic arrays to study seismic structure in the top of the Earth's …

An analysis of core phase travel times is performed in order to estimate the relative
contributions of heterogeneities and anisotropy and their distribution inside the inner core. A …

Broadband velocity waveforms of PKIKP in the distance range 150–180° are inverted for a
model of inner core attenuation due to forward scattering by a three‐dimensional …
