Abstract
Earthquake had occurred in the Korean Peninsula about 2,100 times is not well known in the world. With the true liquefaction judgment is well used to in Korea. Through liquefaction judgements were compared with specifications between Korea and Japan, it would be offered some suggestions for liquefaction judgement used in Korea. The proposals were as 1) It can be known that what kind of earthquake will make unstable state between long-term and short-term earthquake if the natural period of ground turned out. In that case, Hachinohe and Ofunato Earthquake wave will need no more. 2) Liquefaction-induced lateral flow or damage for structure should be estimate but it had not performed in Korea. 3) Heavy rain and ocean wave-induced liquefaction also should be examined thoroughly in slope or ocean, respectively.
