For many natural hazards, including floods, landslides, earthquakes and volcanic eruptions, generating reliable quantitative natural hazard assessments and risk evaluations involve the analysis of detailed empirical catalogues of past events or of time series of measured data, either manually or using computer based Geo-Databases. In recent years geo-databases have been established as essential, often mandatory tools for the investigation of natural hazards. National and international organizations have developed and are maintaining inventories, archives and databases at different scales – from the local to the planetary – as part of their strategy to assess natural hazards and for risk mitigation. Though the technology is available to effectively store and categorize data, such catalogues are difficult to compile and require collection and analysis of historical and pre-historical information using an ample variety of techniques and methods, the results of which aren’t necessarily interoperable. In addition, warning systems for various natural and man-made hazards, including: floods, landslides, earthquakes, volcanic eruptions, groundwater pollution, etc., rely on both historical information and geo-databases to provide accurate, reliable and timely forecasts. The goal of the session is to provide a forum for an in-depth discussion among scientists on two fronts; a) historical data collection/compilation methods and techniques, including stratigraphy, geochronology, paleo-hydrology, paleo-seismicity, history, empirical and statistical methods, estimating and comparing the frequency of the natural events as well as the evaluation of the consequences of present and future climate changes in relation to the spatial and temporal occurrence of hazardous events; b) use of geo-databases for storage and communication of the collected data which will include designing, building, monitoring, updating and using geo-databases, identifying advantages and limitations of existing geo-databases, possible or desirable developments, examples, characteristics and applications of existing or planned geo-databases, conceptual, technical and practical issues concerning the design, maintenance, and update of geo-databases as well as, information technology issues of geo-databases, including: data quality, DBMS technology and performance, database standards (open source vs. commercial systems), GIS integration, geostatistical analysis, WEB publishing, data mining, and the cost of geo-databases in the context of natural hazards.
