Glow reflected on cloud of steam and gas from eruption at summit of Mauna Loa
Photograph by J.D. Griggs at 2:30 a.m. HST on March 25, 1984.

The incandescent glow from lava fountains and flows in the summit caldera of Mauna Loa Volcano is reflected on a cloud of steam and volcanic gas rising from a series of erupting fissures. The eruption began at 1:25 a.m., and the glow was visible from much of the island. After about 4:00 a.m., the activity migrated into the upper northeast rift zone (to the right of the glow) and diminished in the summit area. The view is WNW from the Hawaiian Volcano Observatory, which is located on the rim of Kilauea Volcano's caldera about 30 km from the summit of Mauna Loa.
