What happened to the "Missile Shock" incident?

According to an Agence France-Presse report on January 13, just after 8 a.m. local time, many people in Hawaii said on social networks that their mobile phones had received an Amber Alert managed by the U.S. Department of Justice. A warning issued by the system: "Emergency Alert: Ballistic missile threat approaching Hawaii. Please take shelter as close as possible. This is not a drill. Although the warning text message was quickly determined to be a false alarm, many Hawaii residents still noticed the alarming news. Lauren McGowan, who was on vacation in Maui near Honolulu, said she was on her way out for breakfast when she received the warning message on her phone. Gowan and his family quickly returned to the hotel, where staff took them and about 30 others into an underground restaurant and handed out water and food. McGowan said the text messages and evacuation process caused "confusion", especially for young children. For the most part, no one knew what was going on because many people in the basement couldn't receive cell phone signals. A few minutes later, a customer who could receive cell phone signals underground said it was a false alarm.

Witnesses said the warning was also broadcast on television and radio. Hawaii Live News showed footage of some University of Hawaii students running for cover in the streets, and a weathercaster posted one on Twitter. Photo showing family members hiding in closets after being alerted

Tensions between the United States and North Korea came just before Hawaii residents received the text message asking them to "shelter nearby." For months, North Korea claimed it had successfully tested a ballistic missile capable of reaching the United States with a nuclear warhead, and that the Hawaiian Islands were within range.
