Table 2 The length of a fault zone (L) and the maximum earthquake size [moment magnitude (M _W)] estimated from the empirical relationship by Takemura (1998) and Hanks and Kanamori (1979)

	Fault zone	Length (km)	M _W
Case 1	The Kushigata Range fault zone (KRFZ)	16	6.6 from Eq. (1) 6.2 from Eq. (2)
Case 2	The Tsukioka fault zone (TFZ)	30	7.0
Case 3	The eastern boundary fault zone of the Niigata plain (EBFZNP)	56.5	7.4
