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.
