The Emergency Alert System
Purpose
According to the FCC, "The EAS is designed to provide the President with a means to address the American people in the
event of a national emergency. Through the EAS, the President would have access to thousands of broadcast stations,
cable systems and participating satellite programmers to transmit a message to the public. The EAS and its predecessors,
CONELRAD and the Emergency Broadcast System (EBS), have never been activated for this purpose. But beginning in
1963, the President permitted state and local level emergency information to be transmitted using the EBS."
However, the EAS system is used for much more than to support a method of communication that has never been (and
hopefully never will be) used. The EAS system provides state and local officials with a method to quickly send out
important local emergency information targeted to a specific area. This includes weather alerts as well as local emergency
