List of historical tsunamis

Hi, what was the reason for the removal? Thanks, Dawnseeker2000 01:27, 17 January 2017 (UTC)

Hi. I confirmed that there was an earthquake in 1698 which caused some damage to Bungo Province (Oita Prefecture), but it is doubtful that it involved a large tsunami over Saikaido (not Seikaido) and Nankaido. I also have doubts about the date.

• According to Chronological Scientific Tables by National Astronomical Observatory of Japan, M6.0 earthquake hit Bungo Province on 1698-10-24, caused damage to Oita and Oka Castles, and shook the city of Saga. There is no mention of tsunami.
• Oita Prefecture Board of Education also states the damage to the castles and dates it to 1698-10-24. This one cites 府内藩記録 (The Records of Funai Domain) as primary source, so I think this date is most reliable.
• NOAA's entry for SEIKAIDO-NANKAIDO earthquake dates it to 1698-12-22, citing two sources as references, but neither of them use the term Saikaido or Nankaido.
• Catalog of tsunamis in Japan and its neighboring countries.: Epicenter:"Bungo, Ooita." Remarks: "Earthquake and tsunami."
• A catalogue of tsunamis on the western shore of the Pacific Ocean: "1698, December 22. A tsunami was observed on the coast of Bungo Strait and Oita Prefecture. There are no details. Possibly the date is mixed up and the data relate to some other tsunami." --Aiaiaiaiaia (talk) 10:13, 17 January 2017 (UTC)
