Thurston LavaTube

Nāhuku (Thurston Lava Tube), one of many such tubes on the island, was created by a river of molten lava. When a lava tube is active, lava travels along its floor at temperatures that exceed 2,000º F (1090º C). When the supply of lava stops at the end of an eruption, or if it gets diverted elsewhere, it leaves behind an empty cave.Leggi altro
