Fig. 2From: Examination of one-dimensional S-wave velocity structure using strong-motion data for high-seismic-intensity area during the 2018 Hokkaido Eastern Iburi earthquakeAcceleration waveforms of the transverse component and the spectrogram of the velocity waveforms. The event (Mw 4.3, depth: 32 km) at 21:53 JST on October 8, 2018 was used for these acceleration waveforms. The spectrogram of their velocity waveforms, which were calculated by integrating the acceleration waveforms, was calculated using multiple filter analysisBack to article page
