The Emergency Alert System (EAS) is a national public warning system commonly used by state and local authorities to deliver important emergency information, such as weather and AMBER alerts, to affected communities. It is designed to allow authorized officials to broadcast emergency alerts and warning messages to the public via various mediums, including cable, satellite, broadcast television, and radio. The system also enables the President to address the public during a national emergency within 10 minutes. The EAS is coordinated under the Integrated Public Alert and Warning System (IPAWS), and it is maintained collaboratively by the Federal Emergency Management Agency (FEMA), the Federal Communications Commission (FCC), and the National Oceanic and Atmospheric Administration's National Weather Service (NWS)
. The Wireless Emergency Alerts (WEAs) are short emergency alerts that authorities can send to any WEA-enabled mobile device in a locally targeted area. These alerts are designed to get the recipient's attention with a unique sound and vibration repeated twice. WEAs are not affected by network congestion and will not disrupt texts, calls, or in-progress data sessions. They are sent by authorized federal, state, local, tribal, and territorial public safety officials, the National Weather Service, the National Center for Missing and Exploited Children, and the President of the United States
. In summary, the Emergency Alert System (EAS) is a critical tool for delivering emergency information to the public, and it is used by various authorities to broadcast important alerts and warning messages through different communication channels.
