 HVO scientist measures the episode 12 lava fountain height at Mauna Ulu from Puʻu Huluhulu on Dec 30, 1969. The Mauna Ulu eruption marks its 51^st anniversary on May 24, 1969.

This lava fountain, which erupted on September 6, 1969, during the Mauna Ulu eruption, was about 540 m (1770 ft) tall. The tephra cone, eventually named Mauna Ulu, can be seen in the fallout area (right of the fountains. in middle of image). It is now a 121 m (397 ft) tall lava shield in Hawai‘i Volcanoes National Park.

Lava falls pour into 'Alae Crater at 11 p.m., HST, on August 5, 1969, supplied by a high lava fountain at Mauna Ulu, 600 m (2,000 feet) away. The falls, more than 100 m (330 ft) high and 300 m (1,000 ft) wide, had nearly filled the crater by the time the fountains stopped at 5:45 a.m., August 6.
