SALT LAKE, OAHU (HawaiiNewsNow) - Many people in the Salt Lake and Moanalua areas were woken up by loud siren sounds early Thursday, but authorities said it was a malfunction and there was no emergency.
The warning siren, located at the top of Ala Mahamoe Street in Moanalua, went off just before 4 a.m. and sounded several times over the span of about 30 minutes, according to the City and County of Honolulu.
The Honolulu Fire Department arrived on scene to cut power to the siren to turn it off.
Technicians from the Hawaii Emergency Management Agency will be investigating the cause of the malfunction.
The city said outdoor warning sirens are only activated for testing on the first workday of the month or for actual emergencies.
