Sfondo

Una Una volcano is a broad, low volcano containing a 2-km-wide caldera with a small central cone. Only 3 eruptions are known in historic time, but 2 of them caused extensive damage over much of the island. The last eruption of Una Una was in 1983 and produced pyroclastic flows that swept over most of the island shortly after all residents had been evacuated.

An impressive steam plume is rising from Kamokuna sea entry at Kilauea volcano, Hawai'i.
The lava erupts to the surface at the volcano's eastern rift zone at the Pu'u O'o vent and flows for many miles through an underground lava tube until it reaches the coast.
