Hawaiian-style eruptions are non-explosive eruptions of gusher-like lava fountains (“fire fountains” or “curtains of fire”) that generate red-hot lava rivers of very fluid basaltic lavas. Hawaiian eruptions are typical for shield volcanoes, where eruptions take place both at the summit and at fissure vents.
Typical magma composition: basaltic
Description: Effusive (nonexplosive)
Eruption Products: Pahoehoe lava flows. Pele’s tears, Pele’s hair, and spatter.
National Park examples: Mauna Loa and Kilauea in Hawaii Volcanoes National Park.
