The Emergency Alert System (EAS) is a national public warning system in the United States that enables authorities to disseminate emergency information quickly. It is used to inform the public about severe weather, natural disasters, and other emergencies that may pose a threat to life or property. The system can send alerts through various media, including television, radio, and mobile devices. EAS is designed to ensure that critical information reaches as many people as possible in a timely manner. It is managed by the Federal Communications Commission (FCC) and works in coordination with local, state, and federal agencies, including the National Oceanic and Atmospheric Administration (NOAA) for weather-related alerts.
