Hawaii tested out a Cold War-era nuclear warning siren on Friday, just days after North Korea conducted its latest missile test, which the regime claims is a new type of ballistic missile that is capable of striking any part of the U.S. mainland.

The state is the first to test the warning system, which has not been used since the end of the Cold War, and is an attempt to prepare those on the island for a nuclear attack, amid rising tensions with Pyongyang.

"We believe that it is imperative that we be prepared for every disaster, and in today's world, that includes a nuclear attack," Gov. David Ige said this week, according to ABC News. He also noted that a nuclear strike is unlikely.

Ige said the test will help the public know what actions they should take in the event of a nuclear strike. According to officials, the public would have less than 20 minutes to take cover if Pyongyang did launch a missile.
