USGS Earthquakes — Real-Time & Historical 🌎

Get real-time and historical earthquake data from the official USGS Earthquake Hazards Program as clean, structured JSON. Each event comes with magnitude (and a human-readable class — Micro / Minor / Light / Moderate / Strong / Major / Great), location, depth, tsunami flag, alert level, felt reports, and intensity measures.

Use the standard USGS summary feeds (significant events of the past week, M4.5+ of the past month, etc.) or build custom queries with time, magnitude, and bounding-box filters.

Why use it

• ⏱️ Real-time and historical — pull live feeds or query any date range
• 📏 Magnitude classification — readable class labels alongside the raw number
• 🌐 Split coordinates — latitude, longitude, depth as separate fields (USGS bundles them in an array)
• 🕐 Normalized timestamps — clean ISO 8601 UTC (USGS uses epoch milliseconds)
• 🌊 Full event detail — tsunami flag, alert level (green/yellow/orange/red), felt reports, CDI, MMI, significance
• 🎯 Flexible filters — by time, magnitude range, or geographic bounding box

Use cases

• News & journalism — monitor significant events as they happen
• Risk analysis — insurance, infrastructure, construction
• Research & datasets — historical seismic data for academic work
• Alerts & automation — feed into Slack, email, or webhook pipelines
• Visualizations & dashboards — live event maps and trend charts

Input

Field	Description
Mode	summary (standard pre-built feeds, fastest) or query (custom filters).
Summary feed	Which USGS summary feed (in summary mode).
Start / end time	ISO date or datetime bounds (query mode).
Min / max magnitude	Magnitude range filter (query mode).
Bounding box	min/max latitude and longitude (query mode).
Maximum events	Cap on results (USGS caps queries at 20,000).
