1943-44 eruption: a new volcano is born
Waiowa volcano was born in an area that previously had no volcanic vents and consisted of metamorphic rocks. Following 4 months of seismic activity, intermittent small phreatic explosions began on 18 September 1943 and continued until the first major magmatic explosion on 27 December. Additional explosions occurred on 13 February 13 and 23 July 1944. The eruptions produced pyroclastic flows and lahars, leveling 80 sq km of forest.
After the final eruption on 31 August, the low cone that had formed had a 500-m-wide, steep-walled crater, which is now filled with vegetation and contains a small lake.
