History

Kilauea Iki is a dramatic pit crater located at the summit of Kīlauea volcano on the Big Island of Hawaiʻi. It gained worldwide attention due to its unforgettable 1959 eruption, one of the most notable volcanic events of the 20th century.

The 1959 Eruption: A Volcanic Spectacle

Months before the eruption, Kīlauea Iki showed signs of impending activity, with increased seismic tremors and ground movement indicating magma was rising beneath the volcano. On November 14, 1959, the event culminated when a fissure opened on the western rim of the crater, releasing fountains of lava that soared as high as 1,900 feet. Over the following weeks, molten lava poured into the crater, forming a massive lava lake that eventually covered the entire floor.

Lasting Impact on the Landscape

The eruption left behind a completely transformed landscape. A new cinder cone, Puʻu Puaʻi, was formed, and the terrain of Kīlauea Iki was forever altered. Despite the eruption’s intensity, no lives were lost. The power of nature was on full display, shaping the area into what visitors can experience today.
