Abstract: 

The study presents the testing and results of simulation modeling of surface flows caused by the results of volcanic activity. An analysis of various rheological models was carried out, with a justification for the effectiveness of the Herschel-Bulkley generalized fluid model as applied to geodynamic processes (lahars, mudflows, rockfalls, etc.). The proposed hypothesis was tested and confirmed its viability based on information about a real event – the eruption of the Chaiten volcano. The results of the study can become an effective tool in predicting and assessing the consequences of other geodynamic processes of both endogenous and exogenous origin.
