We are developing an active seismic monitoring methodology on the seismic ACROSS to detect any subtle change of geophysical properties in the Earth's crust. To demonstrate the availability of the seismic ACROSS, which uses coherent seismic waves actively, it may be the best to use several dense arrays routinely. In this study, we briefly review our seismic array observation system by the seismic ACROSS and their specifications, and report the latest results of array observation.
