Analyzing Kilauea Lava Flow Velocities from Drone Flights
This project aims to derive and analyze the velocity of a lava flow site at Fissure 8 from the 2018 Lower East Rift Zone of Kilauea in Hawaii, from drone imagery collected by the USGS. This research is part of a larger project to understand and model multi-phase (lava, bubbles, and crystals) lava flows, and ultimatley better predict lava flow emplacement. I have derived velocity vector fields using particle image velocimetry (PIV), and analyze these data in xarray.
How can I accuratley extract lava flow surface velocity from drone footage?
How does lava flow velocity at Site 6 change throughout a day?
Understanding the flow geometry, and it's affect on velocity...
influence of flow width, and depth on the apparent velocity?
-You can run the code yourself through the binder in Github, or just check out the project in greater depth!

Thank you to the USGS who collected this footage during the 2018 Kilauea eruption!
