Unmanned Aircraft Systems (UAS) conducted a mission on Kīlauea Volcano's lower East Rift Zone to collect video of flowing lava in the upper lava channel of fissure 8. Scientists use the video to assess lava flow velocities, which are measured by tracking surface features in the stationary video view. Using UAS for this type of investigation has many advantages because the aircraft can hover above hazardous areas and it utilizes stabilized gimbals and mounts so that the video captured by onboard HD cameras is steady and smooth. Information obtained from this mission was relayed to Hawai‘i County emergency officials to aid in issuing emergency alerts and notices about the timing of evacuations.
