When is the EAS used? When would a national EAS alert be sent?
The EAS alerting architecture is frequently used by state and local emergency managers to send alerts to the public about emergencies and weather events. While the requirements for carrying a national-level EAS alert differ in some respects from state and local alerts, the national EAS test will test the underlying architecture that also supports state and local alerting. Ensuring that the EAS architecture functions properly will benefit emergency alerting at all levels of government.

The EAS provides the ability to send messages regionally or nationally, though it has never been activated at these levels. But a major disaster like an earthquake or tsunami could necessitate the use of the EAS on a regional or national basis to send life-saving information to the public. We cannot anticipate which communications infrastructure will withstand a particular disaster, but the EAS is one of the tools we have to send alerts, warnings, and information to the American people. The national EAS test will help us improve its capabilities should it ever be needed at the regional or national level in an actual emergency.
