GEOLOGY

Detailed explanation-1: -GENERAL CHARACTERISTICS. Hawaiian eruptions are the calmest of the eruption types. They are characterized by the effusive emission of highly fluid basalt lavas with low gas contents. The relative volume of ejected pyroclastic material is less than that of all other eruption types.

Detailed explanation-2: -Effusive eruptions If a magma has low viscosity (it is runny), gas can escape easily, so when the magma erupts at the surface it forms lava flows. These eruptions are (relatively!) gentle, effusive eruptions.

Detailed explanation-3: -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.

Detailed explanation-4: -1. nvs. Lava flow, volcano, eruption; volcanic (named for the volcano goddess, Pele).

Detailed explanation-5: -Hawaiian eruptions are typically gentle because their lava is highly fluid and thus tends to flow freely both beneath the surface and upon eruption. In contrast, lava of volcanoes located along plate margins, such as Mount St.
