| Research Abstract |
By utilizing density dependent stopping powers of muons, we succeeded to image a volume of a volcano and a fracture zone of a seismic fault with higher resolution than possible with conventional seismic tomography. By developing a power-effective and assembly-type portable muon detector, the following goals were achieved: (1) a method to measure the mass movement inside a volcano three dimensionally before and after the eruption, and (2) a technology to investigate active faults by measuring a distribution and time-dependent changes in a density contrast of a fracture zone.
