Natural disaster in Japan

The 1792 Unzen landslide and tsunami was a volcanic megadisaster, occurring on 21 May 1792, during the Edo period. Triggered by the volcanic activity of Mount Unzen, it caused a massive collapse of the Mayuyama lava dome and a subsequent tsunami. Approximately 15,000 people lost their lives, making it the largest scale volcanic disaster in Japanese history.
