These long thin strands of volcanic glass called Pele's hair were erupted from Mauna Ulu, east rift zone of Kilauea Volcano. A single strand, with a diameter of less than 0.5 mm, may be as long as 2 m. Named for Pele, the Hawaiian goddess of fire, Pele's hair is formed from lava fountains and rapidly moving lava flows (for example, lava cascading over a cliff).
