Similarity of the Fourier phase characteristics between KUMA and JMA for the event No.161. The observed velocity waveforms for the event No.161 at KUMA (black traces) and the phase-exchanged velocity waveforms in which the Fourier amplitude at KUMA and the Fourier phase at JMA, both for the event No.161, are combined (red traces). Both traces are in the frequency range of 0.2–2 Hz
