Volcano Watch: Learning from the impacts of Kilauea’s 2018 LERZ lava flows

Lava flows erupted from the lower East Rift Zone of Kilauea in 2018 and devastated lower Puna. In 2019, a team of scientists from the USGS, the Earth Observatory of Singapore, and GNS Science in New Zealand set out to document and assess the impacts to buildings and infrastructure to advance understanding of how lava flows impact the built environment.
