| | Abstract | | Seismic interferometry synthesizes the Green's function between two receivers by calculating cross-correlation of records measured at their locations. Seismic interferometry using blasting vibration caused by the shafts excavation had been carried out at the Mizunami Underground Research Laboratry. The result was identical to the existing seismic reflection section. In this study, we applied this technique to long time measured microtremor. |
