Aviation disaster triggered by volcanic ashes emitted from the eruption of Eyjafjallajökull in 2010 raised social and economic interest in volcanic ash-related issues in global scale. Increased researches on volcanoes and related disasters are also
of numerical approach to estimate the volcanic ash related disasters. The results show that the computed dispersion agrees well with observational data and the two models reveal about 70% of similarity in the spatial range of the dispersion.
volcanic ash dispersion and its result can be showed on the web interface. In this research, volcanic ash dispersion simulation system is expected to contribute to improving numerical experiments and analysis technique for volcano disaster by carryi
