Unoccupied Aircraft Systems (UAS) video of the 2018 lower East Rift Zone eruption of K'lauea Volcano, Hawaii

This dataset contains Unoccupied Aircraft Systems (UAS) footage from the 2018 eruption of K'lauea 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.

本数据集包含2018年夏威夷岛基拉韦厄火山（K'lauea Volcano）下东裂谷带（Lower East Rift Zone, LERZ）喷发期间的无人航空器系统（Unoccupied Aircraft Systems, UAS）航拍视频素材。此次喷发持续四个月（5月3日至9月5日），形成的熔岩流共摧毁723座建筑，淹没35.5平方千米土地，并为夏威夷岛新增3.5平方千米陆地。本数据集共收录1178段UAS航拍视频，录制时间为5月27日至9月8日，已按月份划分至不同子页面。每月拍摄的视频将按照拍摄日期（YYYY/MM/DD）及拍摄地点打包为压缩文件。各月度子页面均附带一份ReadMe文本文件，其中包含与视频相关的详细信息，包括飞行结束时间、视频时长、起降地点、可见的活跃与非活跃裂隙、关键词以及飞行器型号。其中部分视频为沿8号裂隙熔岩通道及其他多个点位的天底（nadir）悬停视频，用于测量熔岩流流速及开展其他通道监测工作。数据集主页上的一份文档详细说明了这些通道监测点位的位置、视频采集方法以及视频后期处理的相关建议。
