Public Warning & Early Warning
Early Warning focuses on predicting or detecting
a hazard event before it becomes an immediate
threat to life or property
cyclone
earthquake
tsunami
sirens

Public Warning focuses on communicating
to people about a hazard event that is
an immediate threat to life or property

The Challenge of Public Warning
"Collaborative actions are necessary
to assure that standards-based,
all-media, all-hazards
public warning becomes an essential
infrastructure component available
to all societies worldwide."

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

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

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

NEWS -- Federal Communications Commission --May 31, 2007
FCC 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."

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"
