In history, various government-issued alerts have triggered mass hysteria, fear, and confusion. Whether due to poor wording, miscommunication, or unexpected timing, these announcements left people scrambling. These 10 incidents show just how quickly the public can spiral when authority figures sound the alarm.

1. Hawaii Missile Alert (2018)

Residents of Hawaii received a terrifying emergency alert warning of an incoming ballistic missile. The message, marked “This is not a drill,” led to widespread panic — people ran for shelter, called loved ones, and even hid children in storm drains.

2. The War of the Worlds Broadcast (1938)

Although not a government notice, this radio drama was so realistic that many listeners thought it was an actual emergency broadcast about a Martian invasion. Police stations were flooded with calls, highways jammed, and people prayed in churches.

3. The Y2K Bug Warnings (1999)

As the year 2000 approached, government agencies warned that computer systems could fail when clocks rolled over. People stockpiled supplies, pulled money from banks, and expected power grids to shut down.

4. Swine Flu Pandemic Alert (2009)

When the WHO and U.S. health departments issued urgent warnings about the H1N1 flu, fear spread fast. Some schools closed, travel plans were halted, and lines for vaccines stretched for hours.

5. Anthrax Letters and Postal Alerts (2001)

Following 9/11, government alerts about anthrax-laced letters sparked terror across the U.S. Post offices installed biohazard screening, and people feared opening their mail.

6. Cold War Duck and Cover Drills (1950s)

The U.S. government encouraged schools to conduct nuclear attack drills with alarming frequency. Kids hid under desks while sirens wailed, and public notices explained how to survive a blast.

7. False Soviet Nuclear Launch Report (1983)

In the USSR, a satellite system incorrectly reported incoming U.S. missiles. The protocol required retaliation, but officer Stanislav Petrov chose not to escalate.

8. CDC Zombie Apocalypse Preparedness Guide (2011)

Intended as a tongue-in-cheek public health campaign, the CDC released a guide to prepare for a “zombie apocalypse.” It went viral, but some didn’t realize it was satire.

9. Amber Alerts and Mistaken Kidnapping Notices

Amber Alerts are vital, but false alarms or misidentified vehicles have caused public chaos. In several cases, motorists have swarmed the wrong cars, and social media has spread misinformation.

10. COVID-19 Lockdown Announcements (2020)

When governments began issuing stay-at-home orders, it created waves of uncertainty. Panic buying emptied shelves, and rumors spread faster than the virus itself.
