“BALLISTIC MISSILE THREAT INBOUND TO HAWAII,” read a mobile push notification sent around 8 a.m. local time. “SEEK IMMEDIATE SHELTER. THIS IS NOT A DRILL.”

The Hawaii Emergency Management Agency and Honolulu Department of Emergency Management assured Twitter followers there was no missile threat to Hawaii shortly afterward. 

A correction was not sent to mobile phones, however, until around 38 minutes after the initial alert.

“There is no missile threat or danger to the State of Hawaii. False Alarm,” it read.

Honolulu mayor Kirk Caldwell and congresspeople from the state, including Rep. Tulsi Gabbard (D) and Sens. Brian Schatz (D) and Mazie Hirono (D), all posted messages to social media to quell fears, calling the alert a “false alarm.” 

Authorities confirmed there was no impending threat within 5 to 10 minutes of the alert, after contacting the state’s civil defense, Corporal L. Miller of Honolulu Police Department’s Kahuku substation told HuffPost. But why it took so long to notify the public is still unclear.

“If the alert was real, the sirens would’ve went off at the same time,” Miller said, adding that people would have around 15 minutes to take cover.

In the remote town of Haleiwa, more than 30 miles from Pearl Harbor on the island Oahu, residents were confused and afraid when they received the alert.

Some residents pulled over in their cars to alert pedestrians to take cover.

Vanessa Denino was on the southeast side of Oahu visiting her boyfriend and his family in a suburban area when the mobile notifications were sent. Although they didn’t hear sirens or any commotion outside, the group moved away from windows in the home and turned to the internet to figure out what was happening.

“We were really scared,” she said. “It was a really scary time.”

Jamile Qureshi, who lives on the north shore of Oahu, was at the beach with a handful of people including his wife and 5-month-old when everyone’s phones started dinging in unison. 

“We just started freaking out and running,” he said. Qureshi and his wife put their infant and their dog in the car along with water and a few essentials before speeding over to his parents’ home nearby. 

Both Qureshi and Denino noted that there were few, if any, bomb shelters in the area and that homes are generally constructed without basements. 

Chris Wall, a graduate student at the University of Hawaii, had just left his home in Honolulu to go body surfing at a beach on the island’s east side when he received the alert. He immediately turned the car around and sped back to his wife and newborn child.

Once home, the couple began filling water bottles and latching windows shut. They tried to call 911 but the phone wouldn’t ring, Wall said. Eventually they saw a social media post from Rep. Gabbard indicating it was a false alarm.

“It was just complete panic, with neighbors running around looking for insight, looking for cover,” Wall told HuffPost. “Babies crying. Just pandemonium.”

Wall added that state officials need to sort out what went wrong and ensure it doesn’t happen again.

“Thirty-eight minutes is just unacceptable,” he said, referring to the time that went by between the initial alert and the correction. “I’m sure that people were put in serious danger.”

In a statement, Hawaii Gov. David Ige said that although he was “thankful” the alert was only a false alarm, “the public must have confidence in our emergency alert system.”

“I am working to get to the bottom of this so we can prevent an error of this type in the future,” Ige said
