The longest recorded eruption at Kilauea, arguably, was the ʻAilāʻau eruption and lava flow in the 15th century. It was the largest in Hawaiʻi in more than 1,000-years. The flow was named after ʻAilāʻau was known and feared by all the people.
‘Ai means the "one who eats or devours." Lāʻau means "tree" or a "forest." He was the fire god before Pele arrived at Hawaiʻi Island. The image shows the ʻAilaʻau flow (white) with kīpuka pockets in certain areas.
