Mauna Ulu

Mauna Ulu, also rendered Maunaulu, is a volcanic cone on Kīlauea’s eastern rift zone within Hawaiʻi Volcanoes National Park. Its eruption began on May 24, 1969, and lasted until July 22, 1974, making it at the time the longest-lasting and most voluminous flank eruption on Kīlauea in at least 2,200 years. About 350 million cubic meters of lava built the cone and spread flows across forty-four square kilometers, with lava fountains reaching 539.5 meters. The eruption reshaped the landscape around what is now Chain of Craters Road. Now dormant, Mauna Ulu remains a striking volcanic landmark and a vivid record of Kīlauea’s power to rapidly transform Hawaiʻi.
