About The Cover
COVER Lava erupts from fissure 8 on 10 June 2018 in the lower East Rift Zone of Kilauea Volcano, Hawai'i. The erupting lava formed a channel and flowed toward the ocean at Kapoho, Hawai'i. Meanwhile, the summit caldera was collapsing. The vigorous rift zone eruption and summit collapse lasted about 3 months. See page 367.
