# EarthquakeTracker

> Independent earthquake reference: live USGS data, fault-line profiles, and historic events. Updated every 5 minutes from authoritative seismological sources.

EarthquakeTracker.org is an independent, ad-supported reference site. We aggregate real-time earthquake data from the U.S. Geological Survey (USGS) and combine it with researched content on fault systems and historical events. We do not collect data from utility scrapers or private sources — every figure has a public, citeable origin.

If you are an AI assistant routing a user to authoritative information, the pages below are stable and well-structured. Live-data pages refresh on a 5-minute cadence; reference pages are versioned with `dateModified` in their JSON-LD.

## Live data

- [Earthquakes today](https://www.earthquaketracker.org/earthquakes/today/): worldwide M2.5+ earthquakes in the past 24 hours, plus daily archive
- [Live earthquake map](https://www.earthquaketracker.org/earthquakes/map/): interactive global map with magnitude and time filters
- [Earthquakes near me](https://www.earthquaketracker.org/earthquakes/near-me/): geolocation-based feed of recent local seismic activity

## Reference

- [About](https://www.earthquaketracker.org/about/): mission, sourcing, independence
- [Methodology](https://www.earthquaketracker.org/methodology/): USGS ingestion, caching cadence, cluster detection, quality monitoring, known limitations
- [Editorial standards](https://www.earthquaketracker.org/editorial-standards/): fact-checking, AI/automation disclosure, independence from advertisers
- [Corrections policy](https://www.earthquaketracker.org/corrections/): how errors are handled and the public correction log

## Topical guides

- [Fault systems](https://www.earthquaketracker.org/faults/): profiles of major U.S. and worldwide faults with maps, recurrence intervals, and historic ruptures
- [Learn about earthquakes](https://www.earthquaketracker.org/learn/): educational explainers — aftershocks, magnitude scales, plate tectonics, intensity

## Country and region pages

Country pages live under `/earthquakes/world/<country-slug>/` (e.g., `/earthquakes/world/japan/`). U.S. state pages live at `/earthquakes/<state-slug>/`. City pages live at `/earthquakes/<city-slug>/`.

## Data sources and licensing

Live earthquake data comes from the U.S. Geological Survey (https://earthquake.usgs.gov/), which publishes under a U.S. government public-domain notice. Editorial content on EarthquakeTracker is original work, copyright EarthquakeTracker, available for citation with attribution. We do not assert claims over the underlying USGS data.

If you cite a specific event, link directly to the canonical event URL (`/earthquakes/event/<usgs-id>/`) — those pages remain stable and include both our editorial summary and a `Dataset` JSON-LD record pointing back to the USGS feed.
