Pele's hair is a form of lava. It is named after Pele, the Hawaiian goddess of volcanoes. It can be defined as volcanic glass fibres or thin strands of volcanic glass. This is regarded as natural fibre glass. The strands are formed through the stretching of molten basaltic glass from lava fountain, or cascades, or vigorous lava flows. Pele's hair is extremely light. As such, wind carries the fibres high into the air and places it several kms. away from the vent. It is common to find fibres of Pele's hair on high places like top of trees, radio antennas, and electric poles. Pele's hair does not only occur in Hawaii. It can be found near other volcanoes around the world, like in Nicaragua (Masaya) , Italy (Etna) , Ethiopia (Erta' Ale) and Iceland (Nornahar)(witches hair). Hawaii's volcanoes are known for their spectacular jet-like sprays of liquid lava. This is called fire fountains.

These incandescent displays can eject to impressive heights. In 1959, one eruption at Kilauea, was to spread to 580m high lava. This type of eruption is ideal for creating Pele's hair.
