Jumping into a volcanic crater is a rare method of suicide. Mount Mihara in Japan became a notorious suicide site in 1933 following a reported story of a young person's suicide there. Over 1,200 copycat suicides followed. This took place in the ensuing two years, prompting the erection of a high protective fence surrounding the crater which was replaced with a higher fence topped with barbed wire after another 619 people jumped in 1936.
