This view of Kīlauea's East Rift Zone was captured from the summit during today's overflight. Kīlauea's East Rift Zone has been the location of numerous eruptions over the past decades, some brief (days) and some longer-lived (years). In this photo, three prominent lava shields—which form during longer-lived eruptions—are visible: Mauna Ulu, Kānenuiohamo, and Pu‘u ‘Ō‘ō. Mauna Ulu was active from 1969–1974; Kānenuiohamo formed at least several hundred years ago; Pu‘u ‘Ō‘ō was active from 1983–2018.
