Practical use
1. Improvement of hazard evaluation methods, by expanding the set of events that statisics is made upon
2. Expanding the content of hazardous weather warnings with information dedicated to:
- people who may be affected, for instance customized warnings
- people who are involved directly in disaster prevention and mitigation, for instance suggesting evacuation routes
The system is under continual development and testing.
