It is possible that the earthquake and tsunami in Sanriku was an enormous quake that resonated even in the area of the Kurile Trench off the eastern coast of Hokkaido. The earthquake had an estimated magnitude of at least 8.4 on the moment magnitude scale, but may have been as high as 9.0, similar to the 2011 Tōhoku earthquake and tsunami. However, due to the time delay of nearly four hours before the tsunami arrived, there are questions about the exact location of the source. The earthquake measured 8.4 on the moment magnitude scale [1] and was in approximately the same location as the 1896 Meiji-Sanriku earthquake. [8] According to old documents, 1,783 people were killed in the Sendai Domain, and over 3000 horses and men in the Nanbu and Tsugaru domains.

The June 15, 1896 Sanriku earthquake generated devastating tsunamis with the maximum run‐up of 25 m and caused the worst tsunami disaster in the history of Japan, despite its moderate surface wave magnitude (M s =7.2) and weak seismic intensity. There was little awareness of the earthquake because of its distance from shore and because of its character, but the tsunami that ensued was massive and did overwhelming damage on shore and killed 26,000 people.
