Common Alerting Protocol (CAP): The Content Standard of Alerts and Notifications in Disasters and Emergencies presented byEliot Christian, Consultant to WMOtelephone: +41 22 730 81 71 e-mail: echristian@wmo.int presented via remote communications at NMHSs' Participation in Disaster Risk Reduction Coordination Mechanisms and Early Warning Systemshttp://www.wmo.int/pages/prog/dpm/coordination-mechanisms-2007/ Geneva, Switzerland; November 27, 2007

  2. Public Warning of Disasters Common Alerting Protocol (CAP), ITU Recommendation X.1303

  3. CAP Example Commn Alerting Protocol (CAP), ITU Recommendation X.1303

  5. The Challenge of Public Warning "Collaborative actions are necessary to assure that standards-based, all-media, all-hazardspublic warning becomes an essential infrastructure component available to all societies worldwide." http://www.isoc.org/challenge Commn Alerting Protocol (CAP), ITU Recommendation X.1303

  6. The Common Alerting Protocol (CAP) Standard • Compatible with legacy as well as newer transports (WMO messages, news wires, digital TV, Web Services, ...) • Flexible geographic targeting • Phased and delayed effective time, expiration • Message update and cancellation features • May include inline digital images and audio • Version 1.1 approved in October 2005 • Significant uptake, many implementations Commn Alerting Protocol (CAP), ITU Recommendation X.1303

  7. Cautions about Public Warning • Emergency management processes should provide for human judgment between detection of a threat situation and issuing of public alerts, under control of officials with appropriate responsibilities • Where alerting involves existing operational systems, pilot implementations should be in parallel with current operations to minimize confusion and service disruption • In any system of public warning, authentication of senders and targeted receivers is essential • Alerting systems can become targets for deliberate misinformation or denial-of-service attacks Commn Alerting Protocol (CAP), ITU Recommendation X.1303

  8. Cyclone Warning System for Fisherman out at Sea • Pilot Experiment in west coast of India • 80 boats fitted with WorldSpace reception - Encased in water proof enclosure - Pretuned to the assigned channel • Warning messages in MP3 format via Internet to the uplink site • Boats into the sea up to 200 miles • Valuable experience gained in designing the full system WorldSpace Reception on a Fishing Boat Typical CAP-based Alerting Systems

  9. NEWS -- Federal Communications Commission --May 31, 2007FCC TAKES ACTION TO FURTHER STRENGTHEN NATION'S EMERGENCY ALERT SYSTEM "Washington, D.C. - The Federal Communications Commission today adopted [an Order that] requires [Emergency Alert System (EAS)] participants to accept messages using Common Alerting Protocol (CAP) [...] The use of CAP will help to ensure the efficient and rapid transmission of EAS alerts [...] in a variety of formats (including text, audio and video) and via different means (broadcast, cable, satellite, and other networks) [...] In addition, the Order expands the EAS system by requiring participation by wireline video providers." Commn Alerting Protocol (CAP), ITU Recommendation X.1303

  10. ITU Resolution 136 (Antalya, 2006) "The Plenipotentiary Conference [...] resolves to instruct the Directors of the Bureaux [...]to promote implementation by appropriate alerting authorities of the international content standard for all-media public warning, in concert with ongoing development of guidelines by all ITU Sectors for application to all disaster and emergency situations" Commn Alerting Protocol (CAP), ITU Recommendation X.1303
