Details for: Nishinoshima
A submarine explosion from Nishino-shima breaches the surface on October 9, 1973. Steam trails behind individual ejected hot blocks at the margin of the plume. Submarine eruptions began on April 12, 1973. On September 11 a new island was first seen. Lava flows began in September, and three new islands were formed, which joined together during October-November 1973 forming Nishino-shima-shinto. The new island itself was connected to the pre-existing Nishino-shima Island by wave activity after the eruption ended. Photo courtesy of Japan Meteorological Agency, 1973.
