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 …

Modeling dispersed gas-particle turbulence in volcanic ash plumes

M Cerminara - 2016 - ricerca.sns.it
This PhD thesis focuses on numerical and analytical methods for simulating the dynamics of
volcanic ash plumes. The study starts from the fundamental balance laws for a multiphase …

Relationship between infrasound-derived and buoyancy-derived eruption plume volume estimates

T Yamada, H Aoyama, H Ueda - Bulletin of Volcanology, 2018 - Springer
Volume estimations for discrete plumes accompanying short-lived eruptions are potentially
