The Mihara ( Japanese 三原 山 , -yama ) is an active volcano on the Japanese island of Izu-Ōshima . It consists mainly of basalt . Larger explosive outbreaks occur roughly every 100 to 150 years.

activity

1986 saw a series of eruptions with 1.6 km high lava fountains, central chimney eruptions, radial crevice eruptions, ejection , lava flows, lava lake eruptions and a subplinian eruption column up to 16 km high . This corresponds to a volcano explosion index of 3. All 12,000 inhabitants of the island had to be evacuated.

The last outbreak occurred in October 1990.

Suicides

From a vantage point near the crater rim, it was possible to jump straight into the lava. That is why the volcano was often used for suicides . A well-known case was that of the 21-year-old Matsumoto Kiyoko ( 松本 貴 代 子 ) on February 12, 1933. In the same year 944 imitators followed in the same place. Due to the ongoing suicides, a cordon was built in 1936.
