Tracking volcanic plume thermal evolution and eruption source unsteadiness in ground-based thermal imagery using spectral-clustering
C Rowell, M Jellinek, J Gilchrist - Authorea Preprints, 2023 - advance.sagepub.com
Volcanic eruptions are routinely simulated as sustained, jet-like flows of gas and 38 ash.
However, most eruptions in nature are unsteady at the source vent, meaning the 39 flow rate …
