Detection of temporal change of the crustal structure around Mt. Asama using seismic interferometry


Abstract
To detect temporal change of the crustal structure around Mt. Asama, the seismic interferometry method has been applied to Hi-net data. As the results, phase delay has been detected corresponded with eruptions of Mt. Asama on the auto-correlation function of stations MYT and TUM. The phase delay has been also detected corresponded with eruptions on the cross-correlation function between MYT and TUM.
