| | Abstract | | We have been studying the application of seismic ACROSS (Accurately Controlled Routinely Operated Signal System) to monitor the changes of underground state. In order to realize the temporal variation of underground state, information about the structure of the target area is essential. It is ideal to conduct observation of target area using ACROSS and evaluation of the structure of surrounding area and its temporal change simultaneously. For this purpose, we examine the method to obtain inter-station transfer functions on the basis of seismic interferometry from observation records during operation of ACROSS seismic source. Preliminary application to the data observed at the test site in Saudi Arabia shows the validity of this method. |
