The main intended purpose of the Microzonation study is to combine different information about the seismic risk in Vienna (hazard scenarios, local subsoil condition, building-stock, etc.). All the results should be joined into a unified seismic hazard map.
This is primarily useful to identify the most vulnerable parts of urban areas, what can be used in the existing catastrophe management to organize the rescue teams in case of a significant earthquake event. In addition the identification of the more vulnerable seismic zones within the city can have a direct influence on urban planning. In case of existing public utilities and infrastructure in very vulnerable areas this knowledge may have an influence on the ongoing safety precautions.
