Fig. 9From: Surface wave attenuation in the shallow subsurface from multichannel–multishot seismic data: a new approach for detecting fractures and lithological discontinuitiesExample of snapshots of vertical particle velocity field. a Horizontal slice at the surface and b, c two vertical slices at 1.195 s from the origin time defined at the maximum amplitude of the source wavelet. The vertical slices are defined along the dashed lines in a. The survey line is defined along the dashed line at y distance from 0 to 420 m. Red–blue color indicates the vertical particle velocity field. Stars represent source positions. We provide the sequential snapshots as the Additional file 5: Video S1Back to article page
