To understand this discrepancy from the expectation, we simulate seismic wave propagation on Ryugu with a wide range of surface material properties and evaluate maximum acceleration on the surface. over the seismic frequency range. λ … In principle, what we need is a formulation of the seismic source, equations to describe elastic wave propagation once motion has started somewhere, and a theory for coupling the source description to the solution for the equations of motion. periods of S-waves are longer, at least by a factor of 3, than those of P-waves due to differences in wave propagation velocity. Seismic Wave Propagation in Stratified Media presents a systematic treatment of the interaction of seismic waves with Earth structure. Wiwit Suryanto. We will concentrate on the former two problems.

Title. Seismology and Exploration Geophysics, vol 5. I. Subjected to a P wave, particles move in the same direction that the the wave is moving in, which is the direction that the energy is traveling in, and is sometimes called the 'direction of wave propagation'. 2012; Chen et al.
