On October 4 in the United States, the loud “alarm” people are talking about is a nationwide test of the federal Emergency Alert System (EAS) and Wireless Emergency Alerts (WEA), run by FEMA and the FCC.

What alarm is going off on October 4?

It’s not a real emergency.
It’s a nationwide emergency alert test that will:

  • Set off a loud, distinctive tone on:
    • Cell phones (a Wireless Emergency Alert)
    • TVs and radios (Emergency Alert System)
  • Display a message saying it’s only a test and that no action is needed.

This test has been scheduled so authorities can check that the system still works properly in case of a major disaster or national crisis.

When and where does it happen?

  • Date: Wednesday, October 4
  • Time: About 2:20 p.m. Eastern Time (phones, TVs, and radios across U.S. time zones will get it around the same moment).
  • Place: Across the entire United States, hitting:
    • Most cell phones that are on and in range
    • Most TVs and radios connected to normal broadcast systems

If severe weather or a major event interferes, these tests sometimes have a backup date announced (for the 2023 test, the backup was October 11).

What will it sound and look like?

On phones:

  • A loud, jarring tone similar to an Amber Alert or severe weather alert
  • A text-style message on the screen explaining it’s a test and that no action is required.

On TV and radio:

  • Regular programming will be briefly interrupted
  • You’ll hear the classic attention tone followed by a spoken message that it’s a nationwide test only.

Why is this trending and in the news?

People are asking “what alarm is going off on October 4” because:

  • It affects millions of devices at the same time , which gets a lot of attention.
  • News outlets and tech sites have highlighted that every compatible phone, TV, and radio in the U.S. will “go off” almost simultaneously.
  • Online forums and social media often amplify it with:
    • Memes and jokes about “every phone screaming at once”
    • Conspiracy theories and speculation, which officials and journalists have repeatedly said are unfounded.

But official sources are clear: it’s a scheduled test, not a secret operation or a live emergency.

Can you turn it off or avoid it?

  • Some phone settings allow you to toggle certain alerts, but top-level national alerts may override normal settings , depending on the device and carrier.
  • Tech guides and safety advocates have shared advice for people in unsafe domestic or private situations who may need to keep a hidden phone from making a loud noise during the test.
