What is the EAS?

The Federal Communications Commission (FCC) established the Emergency Alert System (EAS) in November 1994. Using new digital technology, the EAS replaced the old Emergency Broadcast System (EBS) as a tool to warn the public about emergencies.
The most common use of the EAS is by the National Weather Service to warn local communities about severe weather warnings. You have probably heard radio stations interrupt their programming to broadcast a tornado warning or seen a TV station or cable system run a "crawl" across the bottom of the TV screen about a severe thunderstorm. That is the EAS (Emergency Alert System).
EAS can be activated nationally by the President of the United States, statewide by the Governor, or locally by authorized city or county officials for other emergencies, ranging from earthquakes to forest fires or hazardous material releases to nuclear war.
In February 2002 the FCC amended its rules for the Emergency Alert System to add a new Child Abduction Emergency (CAE) event code which may be used to activate the Amber Alert Plan messages. (FCC News Release) The FCC has "strongly encouraged" radio, TV stations and cable outlets to voluntarily use the new CAE event code as soon as their EAS encode/decoder equipment can be modified.
The FCC has produced a general information brochure about EAS. You can review or download the brochure by CLICKING HERE.
State EAS Plans are developed by a State Emergency Management Agency (SEMA), while Local EAS Plans are developed by Local Emergency Communications Committee (LECC). Both committees are composed of National Weather Service representatives, emergency management officials, radio-TV broadcasters and cable system operators.
The FCC and SEMA have divided the state into several Local Operational Areas. Within each Local Operational Area, the FCC and LECC have designated at least two Local Primary stations to receive local EAS activation requests from the National Weather Service and authorized city, county, or state officials.
Local Primary Stations broadcast each EAS message with an 8-second warning tone and three short bursts of digital data. These data bursts summarize the emergency and trip EAS receivers located at every other radio, TV and cable outlet in the Local Operational Area so they can voluntarily re-broadcast the state or local EAS message delivered by the Local Primary Stations.
In some states or local areas, the SEMA or LECC has authorized activation of the EAS for reports about missing children believe to be abducted.
The FCC maintains a list of web-sites where several state and local EAS plans are available. CLICK HERE to review the list of State and Local EAS Plan web-sites.
If your state or local area is not listed, you can e-mail the FCC at fccinfo@fcc.gov to request:

The name, address and telephone number of the SEMA or LECC Chairman for your geographic area
The contact person and call letters of the Local Primary stations that serve your geographic area.
A copy of your Local EAS Plan to find out if EAS can be activated for reports about abducted children.
