Under water volcanoes can also have a Lateral blast sideways eruptions meaning the molten rock explodes out of the side of the volcano but also making the same large tsunami wave. The present article presents hydrodynamic model of rela-tively slow process of eruption with domination of liquids. Tsunamis generated by underwater volcanic explosions amplitude tsunamis interpreted as the result of submarine ex-plosions of Ritter Island volcano Papua New Guinea were reported in October 1972 and October 1974 in the Bismarck Sea Cooke 1981.
