Aerial photograph shows the Ka‘apuna lava flow erupted from Mauna Loa in 1950 as it advanced through the forest at about 3,000 feet elevation on the morning of June 2. This rapidly moving ‘A‘ā lava flow traveled from the Southwest Rift Zone vent to the ocean in about 17 hours. Earlier flows from this same eruption reached the ocean in as little as three hours.

Part 1 of 5

Remarkable silent film, 16mm Kodachrome movie film. Probably the first color film ever made of a volcanic eruption. Mokuaweoweo Crater eruption filmed probably in late 1935 by Harold T. Stearns, a USGS Hydrologist-Volcanologist. The lava fountains are hundreds of feet high, the erupting fissure inside the crater is about two thousand feet long. The
