On January 13, 2018, a false ballistic missile alert was issued via the Emergency Alert System and Commercial Mobile Alert System over television, radio, and cellphones in the U.S. state of Hawaii. The alert stated that there was an incoming ballistic missile threat to Hawaii, advised residents to seek shelter, and concluded "This is not a drill". The message was sent at 8:07 a.m. local time.
A second message, sent 38 minutes later, described the first as a "false alarm". State officials blamed a button pushed in error during a shift change at the Hawaii Emergency Management Agency for the first message. Governor David Ige publicly apologized for the erroneous alert, which caused panic and disruptions throughout the state. The Federal Communications Commission and the Hawaii House of Representatives immediately announced investigations into the incident.
