Volcanologist Don Peterson of the Hawaiian Volcano Observatory extracts a sample of fresh lava from an active lava tube during the 1969-74 Mauna Ulu eruption. Asbestos gloves were used for protection against the intense radiant heat. Sampling at various stages of an eruption is used to determine changes in the chemistry and mineralogy of erupted lavas.
