Volcanic unrest and volcanic eruptions are one of the major natural hazards next to earthquakes, floods, and storms. In the framework of this GEOTECHNOLOGIEN project collaborate many partners which will develop the core of a mobile Volcano Fast Response System (VFRS) that can be quickly deployed in case of a volcanic crisis or volcanic unrest. The core of the system builds on established volcanic monitoring techniques such as seismicity, ground deformation, and remote sensing tools for gas measurements. A major novelty of this mobile systems is the attempt of a direct inclusion of satellite based observations to deduce ground deformation, to detect hazardous gas emissions and to monitor thermal activity. The backbone of the VFRS is a wireless communication network tied to a central data base that collects data from the instruments in the field. Using well defined exchange protocols that adhere to international standards the system will be open for novel and promising tools like geoelectric soundings and new spectroscopic methods to monitor gas chemistry during volcanic unrest. The raw data collected by the VFRS will be further analyzed and fed into different models to constrain the actual state of activity at the volcano and to set alert levels. Finally, all information and results will be made available through GIS based visualization tools to communicate the results to local decision makers.
