Hawaiian eruption
A type of volcanic eruption characterized by effusive lava flows and relatively low explosivity, typical of Hawaiian volcanoes.
In a Hawaiian eruption, lava often flows out quietly.
Plinian eruptions are highly explosive and produce massive ash columns, unlike the effusive Hawaiian type.
Compound of ハワイ (Hawaii) + 式 (style/type) + 噴火 (eruption), referring to the eruption style typical of Hawaiian volcanoes.
