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. More than 7,000 homes were extensively damaged and 4,885 were washed away. Here are the worst tsunamis in history. Nope, no thank you.
