This eruption was observed by Hawaiian Volcano Observatory volcanologist Jack Lockwood on 28 February 1974, near the end of the 5-year-long Mauna Ulu eruption. As the erupting lava solidifies around the vent the feature gets progressively larger. Photo by Robin Holcomb, 1974 (U.S. Geological Survey).
