... ), there has been a lingering uncertainty as to whether the degree of amplification varies with the level of input motion. This issue remains as one of the most important questions with respect to understanding and predicting earthquake ground motion. In accordance with the conservation of energy, seismicwave...

... in near- and far-offset stacked data. The necessary input to the method is empirical rock physics equations relating changes in P-wave and S-wave velocities and densities to changes in pore pressure and saturation. For saturation changes, the commonly used equations are the Gassmann equations...

... in this category puts the importance of this work into even starker relief. It has been cited nearly 600 more times than the 16th paper on that list, “Velocity analysis for transversely isotropic media” by T. Alkhalifah and I. Tsvankin (which is an extension of Thomsen's work and, of course, cites it). This paper...

... of the Korean peninsula: (1) a well-defined Moho discontinuity exists in the peninsula with Pn velocity of about 7.7 km/sec, (2) the thickness of the crust is about 35 km, and (3) the layering of the crust is not clear. The average P - and S -wave velocities in the upper crust turned out to be about 5.8...
