What is StorMe used for?
• standardized documentation of past events
• Hazard mapping(retrospective: potential endangered areas; frequency of events)
• Model validation
• Proof of potential danger
• Awareness of population (risk communication)
• controlling of effectiveness (hazard maps, planning technical, organisational measures)
• emergency planning
