The 2018 eruption of Kilauea Volcano: A summer of change and hazard response
Kilauea Volcano’s 2018 activity included a large collapse of the summit caldera that accompanied a vigorous, prolonged effusive eruption on the flank (Lower East Rift Zone). The summit collapse was the largest in the historic record (past 200 years) at Kilauea, and terminated the summit lava lake activity that had persisted for over ten years. The Lower East Rift Zone eruption comprised 24 fissures, one of which produced a high-effusion rate lava flow (>100 m3/s) that persisted for two months. This eruption occurred in middle of a residential subdivision, destroying more than 700 structures and marking the most destructive eruption in Hawai`i in the past 200 years. This talk gives an overview of the eruptive activity, and describes the monitoring and hazard assessment conducted by USGS Hawaiian Volcano Observatory scientists and collaborators.
