抄録: High density seismic observation of controlled source seismic experiment is presented. Purposes of the operation are both evaluation of single channeled observation system and investigation of subsurface structure in the ground deformation source region. The experiment was carried on October 2006. 208 seismometers and recorders were spread with about 50m interval across Kuruma-zaka Pass at 5km west of the active crater of Asama Volcano. Instruments were installed at posi-tions by six persons for three days. 206 stations recorded all five shots successfully. The new sys-tem provided more efficient operation than that with the conventional system. Obtained seismic records are of interest because different appearance in later phases is shown between the shot records in the north and the south sides. It is significant that particular later phases in 2 to 3s of travel times appear in 2 to 3km north of the shot S3. LPF process enhances the northern later phase. It is expected that our observation may provide important constraints for understanding the structure of Asama Volcano.
