This dataset contains Unoccupied Aircraft Systems (UAS) footage from the 2018 eruption of Kīlauea Volcano’s lower East Rift Zone (LERZ), Island of Hawai‘i. The four-month-long eruption, from May 3 to September 5, produced lava flows that destroyed 723 structures, inundated 35.5 km2 of land, and added 3.5 km2 of new land to the Island of Hawai‘i. There are 1178 UAS videos in this publication, recorded from May 27 to September 8, which have been separated into sub-pages by month. Videos taken during each month are separated into zipped files by date (YYYY/MM/DD) and location. Sub-pages for each month also contain a ReadMe text file with information pertaining to the videos, including flight end time, video duration, take off/landing location, visible active and inactive fissures, keywords, and aircraft name. A subset of these videos represents hover videos collected at nadir sites along the fissure 8 lava channel and several other locations for the purpose of measuring flow velocities and other channel monitoring. A document on the landing page describes the locations of these channel monitoring sites and the methodology used for video acquisition and recommendations for processing.
