Table 6 Computed inundation depth at Sekinehama and Odanosawa using six newly proposed fault models

Site	Shallow rupture model			Deep rupture model			Slip (m)
Site	S1	T1	U1	S2	T2	U2	Slip (m)
Sekinehama-GS2	–	–	–	–	–	–	6

Odanosawa-N6	4.0	2.6	0.7	7.2	8.9	8.0	18

The inundation depth was computed at Sekinehma-GS2, which is the most inland tsunami deposit identified by Ishimura et al. (2022), and at Odanosawa-N6, which is the most inland tsunami deposit identified by Tanigawa et al. (2014). The bold number depicts that the most inland tsunami deposits at the two sites could be explained simultaneously
