Seismic Waves: Seismic waves are defined as waves produced on Earth's inner surface due to the activity of earthquakes, volcano eruptions, and other events associated with seismology. Seismic waves can be classified in two types, longitudinal, compressional waves or transverse, shear waves. ...
Dry sandy layerPhase velocityDispersion equationTransform technique.The paper investigates the dispersion of G-type seismic waves along the interface of dry sandy and inhomogeneous isotropic elastic media. The maximum energy flow which projects the fact that a large amount of energy can flow along the...
aAlmost any type of (safe) explosive can be used for seismic work. Often, mush of the energy delivered by an explosion is wasted in shattering rock near the shot point, and seismic waves are produced much more efficiently by shots fired in a metre or so of water. This effect is so ma...

The interpretation of acoustic and seismicmeasurements in porous materials are usually carried out using the Biot theory. This theory predicts the existence of two Pwaves (referred to here as type I and type II) and one Swave. The type I Pwave is predicted to have small dispersion and atten...
Quantitative estimates for the characteristics of inhomogeneous plane body waves in layered low-loss solids are derived and guidelines established for estimating the effect of inhomogeneity on seismic body waves and a Rayleigh-type surface wave in low-loss media. 展开 ...
In an earlier paper, we have obtained the plane wave solutions of the field equations R ij =0 in n-dimensional space-time V n . In the present paper, we have studied these solutions in detail for [x 2 +y 2 +z 2 -t]-type and [t/x 2 +y 2 +z 2 ]-type plane wave...
