Many marine terraces have been developed in the Hwatae-do (island), mid-southern coast of the Korean peninsula. The formation periods of the marine terraces below the ¡®Hwatae 43m terrace¡¯ whose paleoshoreline altitude is 43m above the sea level among the terraces of the Hwatae-do (island) were estimated by the comparison between the marine terraces of the Hwatae-do (island) and the marine terraces of the mid-eastern, southeastern and southwestern coasts of the Korean peninsula. Temporarily, the Hwatae 43m terrace was assumed to be the marine terrace which has been formed in the MIS 9 and the Hwatae 33m, 24m, 19m and 11m terraces correlated to the MIS 7e, MIS 7c or 7a, MIS 5e and MIS 5a respectively. The possibility of the notable vertical displacement by the large-scale different tectonic uplift which had occurred among the marine terrace surfaces in the mid-eastern, southeastern, mid-southern and southwestern coasts of the Korean peninsula was considered not to be high, judging from the comparison of the paleoshoreline distributions in the marine terraces of the above-mentioned coasts after at least the MIS 9.
