[Washimi-kun, posted by miyoki]
To estimate any seismic noise effect on the corner station due to the liquid N2 truck transportation through the SK access tunnel in the past days, Washimi-kun checks the IXV-Z direction time-spectrum around 09:45~10:30 that was announced as the truck traffic time on 22/Oct/18, 22/Dec/6/27, 23/Jan/13/24, 23/Mar/7/24, and 23/Apr/11/25(Noto EQ swarm duration).
We cannot recognize remarkable and characteristic noises.
