Kilauea volcano on the island of Hawai’i is well known for its effusive, fountain-style eruptions. However, its eruptive history is punctuated byexplosive eruptions that would today be a serious hazard to local humanpopulations. Explosive eruptions induced by contact between waterand magma are known as phreatomagmatic, and such an eruption in1790 was responsible for the deaths of roughly 80 Hawaiians.
