| | Abstract | | Field experiment of the passive surface wave method with linear arrays using cable-less seismographs has been conducted for an effective geological investigation at urban area. Dispersion curves to estimate S-wave velocity are obtained at every 10 m by CMP-SPAC method. It enables us to estimate two-dimensional S-wave velocity profile. The result of the field experiment agrees with existing information of subsurface, and encourages us to apply the methodology to the geophysical investigation at urban area. |
