Kīlauea Volcano’s 2018 Lower East Rift Zone Eruption. Kīlauea Volcano’s long-lasting East Rift Zone (ERZ) eruption changed abruptly when the Pu‘u ‘Ō‘ō crater floor collapsed on April 30, 2018, followed by an intrusion of magma downrift. On May 3, lava erupted in Leilani Estates and within two weeks, 24 fissures had opened along a 4.2-mile-long segment of the lower ERZ. Fissure 8 soon became the dominant vent, erupting a fast-moving channelized lava flow that reached the ocean, burying 13.7 square miles of land and destroying over 700 structures along the way. Join USGS Hawaiian Volcano Observatory geologist Carolyn Parcheta as she recounts the progression of this dramatic eruption and shares her experiences monitoring it. Part of Hawai‘i Volcanoes’ ongoing After Dark in the Park series. Free (park entrance fees apply).
When: Tues., April 23 at 7 p.m.
Where: Kīlauea Visitor Center Auditorium
