Hawaii officials also apologized for how long it took to send out an all-clear message correcting that mistake.
Hawaii House Speaker Scott Saiki said the system Hawaii residents have been told to rely on failed miserably.
Longtime residents and vacationers were suddenly jolted into survival mode, hurrying to shelters with scant information and sending loved ones a final goodbye.

Mr Ige said the emergency management agency after the incident ordered a change in its procedures requiring two employees, not just one, to send out such an alert in the future.

FCC Chair Ajit Pai says the agency is launching a full investigation into the mistake.
The U.S. military's Pacific Command and state authorities confirmed that there was no missile threat to Hawaii, which is a chain of islands in the Pacific Ocean, and home to the U.S. Pacific Command.
