The 1959 edition of the Science Chronological Table, which was mistakenly described as “there was a Mexican tsunami” in 1537 (National Diet Library)

The oldest tsunami in the history of Mexico, which is said to have occurred in 1537, which is the period of the Warring States period in Japan, was born because the 1959 version of the “Science Chronological Table” edited by the Tokyo Observatory (now the National Astronomical Observatory of Japan) misrepresented the tsunami. It turned out on the 19th that it was a tsunami. Mr. Yutaka Hayashi, Director of the Meteorological Research Institute (Ibaraki Prefecture), Japan Meteorological Agency, published the survey results in the journal of the Seismological Society of Japan. The oldest Mexico that can be confirmed in the literature is 1732 in the middle of the Edo period.

The phantom tsunami was repeatedly cited in papers without being verified, and although it was evaluated as suspicious, it was reflected in the tsunami’s international database. Research was also conducted on the premise of the existence of a tsunami.
