The 2018 lower East Rift Zone eruption and accompanying summit collapse of Kilauea Volcano, Hawai`i, comprised one of the most impactful events on the volcano in the past 200 years, with hundreds of homes destroyed and major changes in the topography of the summit caldera. The opening stages of this eruptive sequence started on 30 April, when a magmatic dike began moving east from Pu`u`o`o, a cone with a central crater that was the vent region for Kilauea’s 35-year middle East Rift Zone eruption starting in 1983. The rapid migration of magma from beneath Pu`u`o`o caused its crater floor to drop over 300 m. This data release includes a three-dimensional model of Pu`u`o`o and the collapse crater, constructed from aerial thermal images collected on 11 May 2018. Structure-from-motion processing was used to create the model from the sequence of oblique images, and ground control using kinematic GPS was used to georegister the model. These data provide a detailed record of the surface changes associated with the rapid magma migration that occurred on 30 April 2018. These data were used in the gravity study by Poland and others (2020, 2021).
