Keywords:destructive earthquakes, catalogs of Japanese historical earthquakes, Chronological Scientific Tables

We focus on the descriptions in catalogs of Japanese historical earthquakes such as "Chronological Scientific Tables" (the latest edition is 2023) and "Materials for comprehensive list of Japanese destructive earthquakes 599-2012" (Usami, et al., 2013, in Japanese). In particular, we study the dates of destructive earthquakes in the Edo period. Table 1 shows the list of earthquakes studied in this study.

We mainly focus on the "destructive" earthquake at Ise on 1764, which is listed in the Chronological Scientific Tables. The description of "Diary of Geku Korakan" in Ise Jingu Shrine is as below: The other day, in October, the great earthquake caused damage in various places (Earthquake Research Institute, 1983, New collection of historical materials on earthquakes in Japan, vol 3, p. 612).
The expresssion of the damage has been referred to as that of the earthquake on 29 October 1764. However, after examining the original document, it was found that the damage was caused not by the 1764 earthquake but by the 1707 Hoei Earthquake.

In addition, we examine the Kaga earthquake on 1650 and so on.
