A close-up of Pele’s hair from KÄ«lauea Volcano’s summit lava lake. X-ray diffraction analyses of the Pele’s hair (basaltic glass) collected today will provide information on the mineralogy of KÄ«lauea lava, which, in turn, can shed light whether the magma supply to the volcano is constant or is changing.
