🛰️ FIRMS Thermal (Volcanic)
Uses existing NASA FIRMS API to detect thermal anomalies near known volcanoes. Shared API key with Pyro platform.
⚡ About Thor
Thor is a real-time seismic and volcanic intelligence platform by Borealis AI. It integrates USGS earthquake feeds, volcano monitoring data, and tectonic boundary overlays into a single global operational view.
All data is fetched client-side from public APIs — no backend server, no authentication required. Earthquake data updates as frequently as every minute from USGS.
Coverage: Global — all USGS-reported seismic events worldwide
Architecture: Single-file HTML, client-side only, CDN dependencies
Deployment: Drag-and-drop to any static host (Netlify, S3, etc.)
🌍 USGS Earthquake Feeds
Real-time GeoJSON feeds from the USGS Earthquake Hazards Program. Updated every minute. Multiple feed windows by magnitude threshold and time range.
GeoJSON Summary Feeds LIVE
Endpoint: earthquake.usgs.gov/earthquakes/feed/v1.0/summary/
Feeds: all, 1.0+, 2.5+, 4.5+, significant × hour/day/week/month
Auth: None | CORS: Enabled | Format: GeoJSON (RFC 7946)
Data: Magnitude, depth, location, time, felt reports, tsunami flag, PAGER alert, MMI, network, gap, RMS, status
📏 Depth Classification
Earthquake depth determines damage potential. Shallow events (<33 km) cause the most surface damage. Deep events (>300 km) are felt over wide areas but cause less destruction.
● Shallow (0–33 km): Crustal earthquakes. Highest damage potential. Most felt reports.
● Upper (33–70 km): Lower crustal / upper mantle. Still potentially damaging.
● Intermediate (70–300 km): Subduction zone earthquakes. Wide felt area, moderate damage.
● Deep (300–500 km): Deep subduction. Rarely damaging at surface.
● Very Deep (500+ km): Deep mantle. Scientifically significant, minimal surface impact.
🌋 Volcano Monitoring
30 major monitored volcanoes worldwide with alert level tracking. Includes all USGS Cascades Volcano Observatory sites, Alaska Volcano Observatory, Hawaiian Volcano Observatory, and notable global volcanoes.

📊 Magnitude Scale
Earthquake energy increases logarithmically — each whole number increase represents ~31.6× more energy released. Marker sizes on this map scale accordingly.
M < 2: Micro — not felt. 4px markers.
M 2–3: Minor — rarely felt. 6px markers.
M 3–4: Light — felt by many. 10px markers.
M 4–5: Moderate — potential damage. 14px markers.
M 5–6: Strong — damaging. 20px markers with pulse.
M 6–7: Major — destructive. 26px markers with strong pulse.
M 7+: Great — catastrophic. 34px markers with intense pulse.
