Ash clouds and plumes appearing during the explosive eruptions of Kamchatka volcanoes pose a danger to the public and economy, including air transportation and airports. For more than 30 years, scientists have carried out numerical modeling of ash clouds propagation to reduce the danger of air transportation in areas of volcanoes. The paper provides an overview of the main models of ash propagation used by the Volcanic Ash Advisory Centers. Examples are given of using of PUFF and FALL3D models for solving problems related to the operational forecast of ash clouds propagation during eruptions of the Kamchatka volcanoes. Methods considered for clarification parameters of volcanic eruptions using a joint analysis of the simulation results performed by means of the automated information system “Signal” and satellite data from the VolSatView information system.
Keywords: volcanic ash, numerical simulation, remote sensing, information system, VolSatView, AIS Signal, FALL3D, PUFF
