Abstract
Lava domes arc formed during molten lava eruption. Various predictions of flow growth and eruption rate have been offered to minimize lava damage. In this paper. flowing lava is modeled as a Bingham fluid . A continuum mechanics model is presented; both isothermal and temperature-dependent cases arc considered. Height profile predications of domes from this mathematical model arc compared with laboratory results using different slurries. Excellent agreement is found for the isothermal case and qualitative agreement is found for the temperature-dependent case.
