About Kahu Ola
Hawaiʻi Civic Hazard Intelligence Platform
Kahu Ola — meaning "Guardian of Life" in Hawaiian — is an independent civic technology platform serving Hawaiʻi communities with real-time hazard awareness. We aggregate publicly available government data into a single, accessible interface for residents, kupuna, and emergency responders.
Independent civic technology, not a government service. For official directives, always contact HIEMA, your county emergency management agency, or the National Weather Service.
Our Mission
Kahu Ola — meaning "Guardian of Life" in Hawaiian — is an independent civic technology platform serving Hawaiʻi communities. We aggregate publicly available government hazard data from NASA FIRMS, NOAA, the National Weather Service, EPA AirNow, USGS, and PacIOOS into a single, accessible civic intelligence interface.
Built in response to the 2023 Maui wildfires that devastated Lahaina, Kahu Ola exists to ensure no community is caught unaware of unfolding hazards. We are wildfire-first, statewide-aware, and built for the kupuna populations who deserve clear, calm hazard awareness without technical complexity.
Who Built This
Kahu Ola is built and operated by Long Nguyen, an independent civic technologist based in Waikoloa, Hawaiʻi. As a solo developer, Long architected the platform with five immutable invariants that prioritize user privacy (zero PII), data integrity (fail-closed parsing), and graceful degradation (no blank screens, ever).
The platform follows a Cache-First, Privacy-First, Failure-Tolerant architecture designed to remain trustworthy even when upstream government APIs fail. This independence — operating outside both government and commercial interests — allows Kahu Ola to provide unfiltered civic intelligence focused solely on community benefit.
What We Do, What We Don't
Kahu Ola is deliberately scoped. The clearest way to understand the platform is to look at both sides:
What Kahu Ola Does
- Aggregates real-time hazard data from authoritative public sources
- Translates complex government data into clear civic signals
- Provides freshness indicators so users know data age
- Operates with zero personal data collection
- Serves Hawaiʻi communities free, with no advertising
What Kahu Ola Does Not Do
- Issue official emergency directives or evacuation orders
- Replace HIEMA, county emergency management, or NWS
- Collect, store, or transmit user location data
- Charge users or display advertisements
- Represent any government agency
Where Our Data Comes From
Every signal in Kahu Ola traces back to a public, authoritative source. We aggregate, render, and timestamp — we do not generate or estimate hazard data ourselves.
| Agency | Data Provided |
|---|
| NASA FIRMS | Satellite wildfire detections (VIIRS / MODIS) |
| NOAA HMS | Smoke plume polygons |
| NWS Honolulu | Flash flood, fire weather, tsunami, hurricane alerts |
| NIFC WFIGS | Official fire perimeters |
| EPA AirNow | Air quality index |
| USGS HVO | Volcanic activity |
| PacIOOS | Ocean and coastal sensors |
| MapTiler | Base map tiles |
How We Operate
Kahu Ola is built around five immutable invariants. Every architectural decision is checked against these first:
- The client never calls government APIs directly — all upstream data flows through a privacy-preserving aggregator.
- The UI renders under all failure conditions — no blank screens, no infinite spinners.
- Parse failures drop the bad data rather than infer or guess.
- Zero personal information is collected, transmitted, or persisted.
- Estimated or stale data is never presented as official or current.
Open Source & Transparency
Kahu Ola is developed in the open. The full source code, system architecture documentation, and operational principles are publicly accessible. We believe civic technology serving public safety must be auditable by the communities it serves.
The platform's invariants, data sources, and failure modes are documented so any interested resident, journalist, or auditor can verify how Kahu Ola behaves before relying on it.
Frequently Asked Questions
The questions we hear most often from residents, journalists, and partner agencies.
What is Kahu Ola?
Kahu Ola is an independent civic technology platform that aggregates publicly available government hazard data into a single situational awareness interface for Hawaiʻi communities. It covers wildfire detections, flash floods, air quality, fire weather, tsunamis, hurricanes, and storm conditions.
Is Kahu Ola an official government service?
No. Kahu Ola is an independent civic technology project, not affiliated with any government agency. It does not issue evacuation orders or replace official emergency services. Always follow guidance from HIEMA, county emergency management, and the National Weather Service for official directives.
Where does Kahu Ola's hazard data come from?
Kahu Ola aggregates publicly available data from NASA FIRMS (satellite wildfire detection), NOAA HMS (smoke plumes), the National Weather Service (alerts and warnings), NIFC WFIGS (fire perimeters), EPA AirNow (air quality), USGS HVO (volcanic activity), PacIOOS (coastal sensors), and MapTiler (map tiles).
Does Kahu Ola track my location?
No. Kahu Ola collects zero personal information. We do not track location, store device identifiers, or transmit personal data. All proximity calculations happen on your device only. See our Privacy Policy for full details.
Is Kahu Ola free?
Yes. Kahu Ola is completely free with no advertising and no tracking. It is operated as an independent civic technology project serving Hawaiʻi communities.
Which Hawaiian islands does Kahu Ola cover?
Kahu Ola covers all Hawaiian Islands: Maui, Hawaiʻi (Big Island), Oʻahu, Kauaʻi, Molokaʻi, and Lānaʻi. Coverage is wildfire-first with Maui as primary focus, but all hazard signals are statewide. Future expansion to US Pacific territories under the Kahu Ola Network branding is planned.
How fresh is Kahu Ola's hazard data?
Data freshness varies by source. NASA FIRMS satellite detections update every 5-15 minutes. NWS alerts are real-time. Fire perimeters from NIFC update as conditions warrant. Every signal in Kahu Ola displays its source timestamp so you can verify data age.
Who built Kahu Ola?
Kahu Ola is built and operated by Long Nguyen, an independent civic technologist based in Waikoloa, Hawaiʻi. It is a solo civic technology project built in response to the 2023 Maui wildfires that devastated Lahaina.
