Figure 3. Seismic profile showing
seismic units (Lee and Suk, 1998)
In the eastern continental margin, the steep slope has been dominantly shaped by large-scale
slope failures and associated mass flow deposits (Chough et al., 1991; Lee et al., 1991). In the
eastern margin of the East Sea, mass failure scars and slide/slumping deposits are very
common along slope areas at water depths greater than about 500 meters in the Ulleung Basin
(Figure 4; Lee et al., 1996) and in the Korea Plateau (Figure 5; Lee et al., 1991). According to
Yoon and Chough (1993), large-scale mass flow deposits predominate in the late Miocene and
early Pliocene sequence (Figure 6).
