Hazard maps are evolving from something you “see” to something you “feel.”

Real-time disaster information is taking shape with AI and IoT.

Many of us receive paper hazard maps in the mail. They indicate flood risks in our neighborhoods, but will they truly help in an emergency? Disasters rarely unfold exactly as predicted.

That's why development is now underway for real-time hazard maps — a new generation of systems that go beyond the limits of static information. Powered by AI (Artificial Intelligence) and IoT (Internet of Things), these maps visualize "current danger" as it unfolds.

How Do Real-Time Hazard Maps Work?

Using the "eyes" of the city

AI analyzes video from security cameras installed throughout cities. It automatically detects flooded roads and hazardous conditions in real time.

Building an IoT sensor network

Low-cost sensors mounted on streetlights, manholes, and other infrastructure measure flood depth and monitor soil movement, sending precise local data continuously.

Analyzing social media information

AI collects disaster reports from platforms such as X (Twitter), eva1uates their credibility, and then reflects reliable information on the map.

Together, these sources transform scattered pieces of information into a unified, up-to-the-minute picture of risk.

Turning Information Into Action

The purpose of real-time hazard maps is not just to show data — it is to help individuals make personal decisions about safety and evacuation.

“The hazard map said my area was safe… but the street outside my house is flooding.”

“The road I always take is closed.”

When such urgent conditions appear instantly on a map on your smartphone, the sense of risk becomes real.

Hazard maps shift from something “given to you” to something you can “feel” as they change moment by moment.

The power of technology encourages action — helping us protect our lives before it's too late.
