Abstract: This paper describes the assessment of the consequences of technological disasters using varied approaches to data analysis. Satellite observation data are used in the context of integrated modelling of ecosystems to reduce the uncertainties of decision support inherent in the field of disaster mitigation measures. By using Earth observation data as the information with higher spatial integration, various pollution scenarios have been calculated taking into account the observed responses of ecosystems and expected evolution. Superposition analysis of vegetation and water indexes allows to identify biophysical disturbances, and the driving forces of ecosystem changes caused by external impact can be investigated. On the basis of scenarios obtained, the socio-ecological threats and deferred risks of different types of technological disasters have been identified with local natural and anthropogenic features. The calculated set of disaster scenarios allows to elaborate recommendations to narrow the methodological gaps in existing national emergency response services to reduce the uncertainties.
