Table 5 Computed inundation depth at Sekinehama and Odanosawa using the modified previously proposed models

Site	Fault model
	HEKT model: Hokkaido (2012) model excluding Kuril Trench part			Hidaka model: Cabinet Office (2020) model excluding Sanriku part
	HEKT (base)	HEKT-1	HEKT-2	Hidaka (base)	Hidaka-1	Hidaka-2
Sekinehama-GS2	4.9	2.9	0.2	4.5	2.7	–
Odanosawa-N6	4.0	0.8	–	6.4	3.0	–
Mw	8.87	8.76	8.59	8.72	8.65	8.57

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 shows that the most inland tsunami deposits at the two sites could be explained simultaneously
