The Hansin Great Earthquake of January 17, 1995, was the most damaging seismic event in Japan since the Kantou Great Earthquake of 1923. At the event, an earthquake observation system measured the motions of LNG Aboveground Storage in Osaka Gas Senboku Terminal II. Probably, the observation of such large motions of LNG Aboveground Storage is the first case in the world, so far.LNG Aboveground Storage responses through foundation and ground at earthquake.It is very difficult to try an experiment of total system which is composed of storage, foundation and ground, except for an observation of motions at earthquake. Because there is a limit to scale up the ability of shaking equipment. The probability that a storage will encounter a large earthquake in the life is very small. SO, actually it is necessary to observe for a long time. The Hansin Great Earthquake is the first large motions from August 1983 when the system started to observe the motions.Then, we verified the seismic design of LNG Aboveground Storage using the records of measured large motions and proved the adequacy of present seismic design (elastic method).
