Disaster Management
1.Risk knowledge• Systematic collecting of data relative to the
events• Risk evaluation
2.Environmental Monitoring and Alert Services• Development of monitoring systems • Creation of a quick and accurate Alert service at
international, national and local level
3.Diffusion and communication• Maximum alert distribution• Clear and simply Alert format
4.Answer Capacity • Creation of national and local systems able to
front the emergiencies.6

CAP – Common Alerting Protocol:
Simple ad general format based on XML for the exchange of Alert Messages on every kind of network Permits the creation of Messages:
• To be distributed on different Alert Systems
• To be used to normalize the information coming from different sources.
