How the map thinks
Turning global events into live pressure signals.
The system ingests incidents, filters them into signals, and computes a live pressure score for each country. Scores summarize recent pressure, not future predictions.
Pipeline walkthrough
Each ingest run passes through a fixed sequence: parse → normalize → relevance filters → deduplicate → cluster → score → publish. The highlight bar above tracks the active stage as you scroll.
What the system observes
- Country-tagged incidents from trusted feeds and local sources.
- Event metadata: time, category, severity, and source reliability.
- Explicit location signals when available (city/region).
What counts as a signal
Pressure is built from severity, category, source reliability, and time—no single factor dominates the outcome.
What is filtered out
- Duplicates across sources for the same event.
- Events without enough metadata to score reliably.
- Out-of-window incidents beyond the 30-day memory.
Filtering exists to keep the map responsive and reduce false amplification.
Why silence ≠ safety
Pressure, not prediction
This system does not forecast future events. Pressure scores are summaries of recent incident density and intensity.
Limits (by design)
- Not predictive. No future forecasting.
- Not real-time ground truth. Feeds are delayed and incomplete.
- Not a replacement for local context and on-the-ground reporting.
Time & decay
Decay is memory fading. Old events matter less each cycle.
The decay floor prevents permanent inflation, even in high-activity regions.
Technical details
Why pressure scores jump
Sudden color changes usually indicate clustered recent events, not long-term deterioration.

Bands and confidence
Confidence reflects coverage, not calm. Low confidence means the system cannot see clearly.
Step-by-step pipeline
- Events: load incident reports and country registry.
- Signals: deduplicate and discard low-information items.
- Pressure: calculate impact per incident and sum it.
- Decay: fade previous pressure to prevent stale inflation.
- Score: update pressure score and clamp between 0–100.
- Band: map to Stable, Moderate, Unstable, Severe.
