The Emergency Alert System (EAS) is a national warning system in the United States put into place on January 1, 1997 (approved by Federal Communications Commission (FCC) in November 1994), It pops up on your tv, radio, or phone for example if a tornado comes it will be on the news, radio, or phone and when it is over the national weather service will say you can come out. The most serious alert that can be given out over the EAS is an Emergency Action Notification. When an EAN is issued, a voice will say the following whilst watching TV or listening to the radio; "We interrupt our programming. This is a national emergency." After the alert tone, the text to speech voice will give instructions on the emergency and provide instructions on what to do to stay safe. There also may be additional messages given out from a .represensitive of the President. An Emergency Action Termination message will be issued when the threat is over. Additionally, there will be a nationwide test of the EAS that takes place in the US once a year along with a new presidental alert system that works very similar to weather warnings that are issued on a cell phone.
