| Abstract: | Some results are presented from an experimental study of the natural microtremor field on an active landslide-prone slope using a KMV seismometer. Anomalous zones of increased microtremor amplitude have been identified within this landslide feature corresponding to zones of density deficit. It is shown that the velocity characteristics in the upper portion of the cross section can be estimated from spectral ratios of horizontal and vertical signal components in three-compont records. The present microtremor mapping results were compared with those derived via other geophysical techniques, in particular, directional surveys and differentazimuth multiwave seismic prospecting. |
