Goal of this work package is to provide the data base including GIS capability and visualization tools and the determination of alert levels. The success of the fast response system including early warnings lives through its connection capability to already installed monitoring systems and the new wireless network as well as through its combination of different raw and model data. At present none of the existing databases are able to handle the multi-parameter data resulting from modern volcano moni­toring networks simultaneously which are quite common today to assess volcanic activity. In practice this means a high-dimensional, complicated (raw or already parameterised) data stream with different sampling rates and time histories that have to be stored and analysed. The success of the system will be closely tied to the systems capability to visualize the results of the data analysis as well as results from model calculations. Part of the data recorded (e.g. gas measurements) can be displayed directly whereas, for example, seismic data need to be processed to determine e.g. hypocenters (see WP5).

All direct data as well as analysis results are stored in a GIS based meta data base and tools will be developed to either look at the data in real time or to visualize the temporal evolution over a certain time period. Taking all recorded data as well as the temporal evolution of the system into account automatic alert levels will be determined. By overlaying existing GIS systems on land use, vulnerable objects, and critical industrial complexes etc, existing evacuation plans as well as evacuation routes can be reconsidered in the light of the current activity and the results of model predictions.
