Volume, effusion rate, and lava transport during the 2021 Fagradalsfjall eruption : results from near real-time photogrammetric monitoring
The basaltic effusive eruption at Mt. Fagradalsfjall lasted from 19 March to 18 September 2021, ending a 781-year repose period on Reykjanes Peninsula, Iceland. By late September 2021, 33 near real-time photogrammetric surveys were completed using satellite and airborne images, usually processed wit...
