VGP paths (top plot) and time evolution of the VGP latitude (bottom plot) from the Chiba and Yanagawa sections. Data are based on the progressive thermal demagnetization of Suganuma et al. (2015). The temporal profile was calculated from the most recent age model of Suganuma et al. (2018). 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
