The Civil Defense monthly test of the statewide outdoor siren warning system, coordinated with the test of the live audio broadcast segment of the Emergency Alert System, is scheduled for Thursday, November 1, 2012, at 11:45 a.m. It is a good idea to listen to a local radio stations (listed below) during the monthly test to ensure you can receive the Emergency Alert Messages which are broadcast in conjunction with the monthly siren test.

The Siren Test is a steady one minute tone on all sirens. The steady tone is used to alert the public to any emergency that may pose a threat to life and property. Besides natural hazards, the Emergency Alert System could be used for terrorist incidents or acts of war.

Oahu residents in areas surrounding Campbell Industrial Park, Honokai Hale, Makakilo, Kapolei Regional Park, Kapolei Golf Course, and the Coast Guard Station at Kalaeloa may also hear a “whooping” tone following the Siren Test. This “whooping” tone is a test of the Hazardous Materials (HAZMAT) Incident outdoor siren warning group that will be activated in the event of a HAZMAT incident. Contact the City and County of Honolulu Department of Emergency Management at (808) 723-8960 for more information or to report siren operations issues. Oahu residents may also sign up to adopt a siren at

When the siren signal is sounded in your area, tune to any local radio or television station for emergency information and instructions broadcast by civil defense agencies. Participating stations will carry a detailed explanation of what the sirens mean, as well as other related information, during the monthly test.

Tests of civil defense sirens and the Emergency Alert System are conducted simultaneously, normally on the first working day of the month, in cooperation with Hawaii’s broadcasting industry. Civil defense disaster preparedness information is located in the front section of telephone directories in all counties.

      If you suspect a problem with the EAS siren system you can report a problem to:

      Hawaii County Civil Defense Agency
      920 Ululani Street, Hilo, HI 96720
      (808) 935-0031 | (808) 935-3311 (after hours) | Fax: (808) 935-6460



      The Hawaii County Police Department did say police and fire personnel would be monitoring all 71 sirens on the Big Island so they can note any problems with them working during the 11:45 a.m. test. But if you want you can drop them a message and let them know. I’m not sure where the Waimea siren is located.

    Aloha, the Kaumakani area on Kauai didn’t go off today. Why?

  3. Dave says:

    Why did the siren go off at 3:10. No one answering phones at civil defense, nothing on the radio, nothing on the news
