Pu'u 'O'o eruption, Kilauea Volcano, Hawaii. Aerial view, from the southwest, of flow near Pu'u Kamoamoa, a prehistoric cone approximately 3,500 m northeast of Napau Crater, in Kilauea's middle east rift zone. Episode 1 (January 3 - 23, 1983) was characterized by eruptions from fissures several hundred meters long. The fountains from these eruptions produced a series of low spatter ramparts (photo by J.D.
