What is CAP?
What are the CAP elements?
Every CAP messages has elements to identify the current emergency alert. Check the elements, values and categories that are part of these messages:

Public, Restricted, Private.
Geological, Meteorological, Safety, Security, Rescue, Fire, Health, Rescue, Infra, Other.
Headline: Hazard and alerting area.
Description: Information about the risk.
Instruction: Call to action to communities in that area.
Urgency: Immediate, Expected, Future, Past.
Severity: Extreme, Severe, Moderate, Minor.
Certainty: Observed, Likely, Possible, Unlikely.
How does it work?
The CAP uses XML digital standard format for exchanging emergency alerts that allows a consistent alert message to be disseminated simultaneously over many different communication systems. The XML base data format (in computing Extensible Markup Language) allows to be processed by software and networks worldwide. When the key messages are carried in the CAP message format the emergency alert is suddenly far more accessible.
Watch an example on how to use the Common Alerting Protocol in a simple way through the Hazards App developed by the Global Disaster Preparedness Center based on the Public Awareness and Public Education (PAPE) key messages, a guide published by the International Federation of the Red Cross Red Crescent Societies for disaster risk reduction.
How to be involved?
CAP Implementation Workshops provide a forum for implementers of CAP and associated organizations to discuss how best to expand adoption of the CAP standard and to share practices among users of the standard. There is no charge to participate and anyone interested in emergency alerting is welcome: managers, technical staff, media, etc., including commercial organizations, governments, and non-governamental organizations.
