WebOct 1, 1985 · A curved wavefront generates a local SP -phase: a P -headwave which propagates along the free surface, and arrives shortly before the direct S -wave. These two arrivals give rise to cruciform particle motions in the sagittal and horizontal planes, which could be misinterpreted as anisotropy-induced shear-wave splitting. WebThree classes of scattering mechanisms have been recognized: repeated specular reflection of primary waves in a uniformly layered structure, volume scattering of primary waves from localized volume heterogeneities, and scattering of primary waves from irregularities in an otherwise generally layered structure. britney birthday
