Hyogo-ken Nanbu Earthquake hits the Kobe Port which is one of major ports in the world, on the 17th JAN. '95. The aftermath is quite devastating. The prevailing facility is a gravity type quaywall which is mainly caisson. So damage paterns look like similar. A typical patern is that a caisson slides about 2m, settles about 1m, and tiltes a little with some 2m deep drops of apron area. This earthquake originates from fallts near the Kove City which is one of major centers of population in Japan. This earthquake has a big vertical component and a bigger NS horizontal component. Quaywalls suffer bigger deformations in Ns direction. Breakwaters are free from sides forces, then just settle down about 2m. Port Island and Rocko Island are man made islands in the Kobe Port. Both Islands have quaywalls and seawalls surrounding themselves which suffer severe damages without restrictions, but new high rize buildings of the order of 40F suffer no noticeable damage, on Islands.
