* docs: restructure documentation into focused, navigable pages (#docs-reorg) Break the 4096-line documentation.mdx monolith into 13 focused pages organized by feature area. Reorganize Mintlify navigation from 5 generic groups into 7 feature-based groups. Move Orbital Surveillance from Infrastructure to Map Layers where it belongs. - Extract: signal-intelligence, features, overview, hotspots, CII, geographic-convergence, strategic-risk, infrastructure-cascade, military-tracking, maritime-intelligence, natural-disasters, contributing, getting-started - Append to: architecture.mdx (9 sections), ai-intelligence.mdx (3 sections) - Fix legacy .md links in map-engine.mdx, maps-and-geocoding.mdx - Slim documentation.mdx to an 80-line index/hub page - Eliminate duplicate content that caused repeated headings * fix(docs): remove duplicate H1 headings from all Mintlify pages Mintlify auto-renders the frontmatter `title` as an H1, so having `# Title` in the body creates a doubled heading on every page. Remove the redundant H1 (and repeated description lines) from all 31 .mdx files.

title: "Natural Disaster Tracking"
|
|
description: "Multi-source natural disaster monitoring using GDACS and NASA EONET, with intelligent deduplication and filtering for earthquakes, wildfires, cyclones, and more."
|
|
---
|
|
The Natural layer combines two authoritative sources for comprehensive disaster monitoring, providing real-time alerts with severity assessments and satellite-derived event detection.
|
|
|
|
## GDACS (Global Disaster Alert and Coordination System)
|
|
|
|
UN-backed disaster alert system providing official severity assessments:
|
|
|
|
| Event Type | Code | Icon | Sources |
|
|
|------------|------|------|---------|
|
|
| Earthquake | EQ | Red circle | USGS, EMSC |
|
|
| Flood | FL | Wave | Satellite imagery |
|
|
| Tropical Cyclone | TC | Cyclone | NOAA, JMA |
|
|
| Volcano | VO | Volcano | Smithsonian GVP |
|
|
| Wildfire | WF | Fire | MODIS, VIIRS |
|
|
| Drought | DR | Sun | Multiple sources |
|
|
|
|
**Alert Levels**:
|
|
|
|
| Level | Color | Meaning |
|
|
|-------|-------|---------|
|
|
| **Red** | Critical | Significant humanitarian impact expected |
|
|
| **Orange** | Alert | Moderate impact, monitoring required |
|
|
| **Green** | Advisory | Minor event, localized impact |
|
|
|
|
## NASA EONET (Earth Observatory Natural Event Tracker)
|
|
|
|
Near-real-time natural event detection from satellite observation:
|
|
|
|
| Category | Detection Method | Typical Delay |
|
|
|----------|------------------|---------------|
|
|
| Severe Storms | GOES/Himawari imagery | Minutes |
|
|
| Wildfires | MODIS thermal anomalies | 4-6 hours |
|
|
| Volcanoes | Thermal + SO2 emissions | Hours |
|
|
| Floods | SAR imagery + gauges | Hours to days |
|
|
| Sea/Lake Ice | Passive microwave | Daily |
|
|
| Dust/Haze | Aerosol optical depth | Hours |
|
|
|
|
## Multi-Source Deduplication
|
|
|
|
When both GDACS and EONET report the same event:
|
|
|
|
1. Events within 100km and 48 hours are considered duplicates
|
|
2. GDACS severity takes precedence (human-verified)
|
|
3. EONET geometry provides more precise coordinates
|
|
4. Combined entry shows both source attributions
|
|
|
|
## Filtering Logic
|
|
|
|
To prevent map clutter, natural events are filtered:
|
|
|
|
- **Wildfires**: Only events < 48 hours old (older fires are either contained or well-known)
|
|
- **Earthquakes**: M4.5+ globally, lower threshold for populated areas
|
|
- **Storms**: Only named storms or those with warnings
