O'ahu siren map

This is a map of all active outdoor warning sirens across the entire Island of O'ahu. It's best viewed on a PC, but is also compatible with your mobile device's browser. Every location on this map was visited & verified in person to confirm each location's accuracy. Some siren locations feature photos & videos that I've taken over the years. Abandoned and disconnected sirens are not listed on this map, this map features active sirens only. For security reasons, images of sirens aboard military installations have been limited.
