Alaska participated at 10 a.m. in the first-ever test of the Emergency Action Notification system, designed to alert the entire nation in the event of an emergency.
At about 10 a.m., the three-minute test alert was heard on the radio and seen on local and cable TV, according to the Alaska Division of Homeland Security and Emergency Management.
Audio indicated that it was a "test," but what viewers saw on their TV screens may not have, the division said.
The division asks that people go to ready.Alaska.gov/test to give feedback on their test reception.
The test was similar to testing conducted by state and local authorities each year for the Tsunami Warning System and the Amber Alert System. But this test involves a national public warning system that allows the president to address the country during a national emergency.
This test was conducted by the division, the Alaska Broadcasters Association and the State Emergency Communications Committee, the Federal Emergency Management Agency and the Federal Communications System.
Alaska was chosen to be the first state to test the EAN because of its isolation and Alaskans' familiarity with tsunami tests, the division said.
