Mr. Fukuo Yuminamochi, who was a professional photographer and living in Niigata, took still photographs and motion pictures of ongoing liquefaction and the damaged Niigata City from the air at the onset and immediately after the 1964 Niigata earthquake. This earthquake was an epoch-making disaster after which liquefaction has been attracting significant engineering concerns. Obviously, Mr. Yuminamochi’s imageries helped concerned people understand this phenomenon correctly and were unforgettable achievement. It is important that Mr. Yuminamochi was able to take those imageries as a consequence of remarkable combination of miracles that he was ready to do his job with cameras, films, aircrafts, fuels and supporters ready. In 2023, he transferred all of his imageries to the care of the Japanese Geotechnical Society so that they might be open to free use. In this context, the present paper explains the photographs with, if available, more information added. As an open resource, Mr. Yuminamochi’s products can be used by anybody for good purposes without acquiring the permission of the Society. Only one requirement is that the photographs are presented with a credit that they were taken by Mr. Yuminamochi and that they are now preserved by the Japanese Geotechnical Society.
