# Namazue

> Real-time global multi-hazard intelligence console at namazue.dev

Namazue is a free, operator-grade spatial intelligence platform that monitors earthquakes, wildfires, storms, volcanic activity, and other natural hazards worldwide in real time. It combines data from authoritative sources (USGS, JMA, NASA FIRMS, GDACS, EONET, NWS) with ground motion prediction equations (GMPE) and infrastructure impact analysis to provide situational awareness for critical infrastructure operators.

## Key Facts
- URL: https://namazue.dev
- Type: Web application (no install required)
- Cost: Free for public use
- Languages: Japanese, English, Korean
- Data update frequency: Every 45 seconds to 10 minutes depending on source
- Coverage: Global (originated as Japan-focused, now worldwide)

## What Namazue Does
- Displays real-time earthquakes from USGS and JMA on an interactive dark-themed map
- Models seismic intensity using Si & Midorikawa 1999 GMPE (Ground Motion Prediction Equation)
- Assesses infrastructure impact: ports, rail, hospitals, power plants within affected zones
- Monitors wildfires via NASA FIRMS satellite hotspot data
- Tracks global disaster alerts from GDACS (Global Disaster Alert and Coordination System)
- Provides depth cross-section analysis for earthquake clusters
- Visualizes active fault lines and historical earthquake catalogs (1900-present)
- Supports 3D building visualization via Japan's PLATEAU 3D city models
