VGP paths (top plot), paleomagnetic intensity indices (middle plot), and time evolution of the VGP latitude (bottom plot) of the CbCS. The integrated results of the hybrid demagnetization method from the Yoro River and Yoro-Tabuchi sections (Okada et al. 2017; Simon et al. 2019; this study). The relative paleointensity is based on the newly calculated NRM30-50/ARM30-50 reported in this study. The BeDM profile, shown by a blue band, is from Simon et al. (2019). Blue vertical shades and gray vertical dashed line indicate millennial-scale VGP fluctuations and the M-B boundary, respectively. Ages of the Byk-A and Byk-E tephra beds are indicated by red arrows. IC, instability cluster; PS, polarity switch
