Subaerial Eruption
A subaerial eruption is any sort of volcanic eruption that occurs on the Earth's surface, or in the open air 'under the air', and not underwater or underground. They generally produce pyroclastic flows, lava fountains, and lava flows, which are commonly classified in different subaerial eruption types, including Plinian, Peléan, and Hawaiian eruptions. Subaerial eruptions contrast with subaqueous, submarine and subglacial eruption Subglacial eruptions, those of ice-covered volcanoes, result in the interaction of magma with ice and snow, leading to meltwater formation, jökulhlaups, and lahars.
