The Big Island Lava Tubes are located on the Big Island of Hawaii. These lava tubes are formed after the Earth’s crust forms over a lava flow, insulating it. Then, the lava “downcuts” through the ground resulting in thermal erosion. Once the eruption, the lava trains, leaving behind the lava tube. Native Hawaiians put cultural significance on the lava tubes, using them as a shelter, a shortage location, and a location for ceremonies and burials.
