Abstract
Multi-station analysis of surface wave dispersion to evaluate the near subsurface has been used in geotechnical applications for more than 15 years. A fiber optic cable used as array of distributed horizontal component seismic receivers for the analysis of surface wave dispersion is used in an extended setup here by the recording of active hammer blows. Their first analyses reveal low-frequency signal recordings with good continuity that can be used for further processing.
