Rock shear wave velocity
Web20 Apr 2016 · The shear wave velocity and bulk density values for the rock data varied from between 130–4000 m s-1 and 1.26–3.05 g cc-1. This data was added to the densities and shear wave velocities from the study area, and a new correlation was developed, as given … WebThree component recordings from an array of five ocean bottom seismographs in the northwestern part of the Voring basin have been used to obtain a 2-D shear-wave (S-wave) velocity-depth model. The shear waves are identified by means of travel-time differences compared to the compressional (P) waves, and by analyzing their particle motions. The …
