USGS earthquakes
earthquake.usgs.gov/fdsnws/event/1
Every earthquake above the chosen magnitude threshold, worldwide, across the entire history of the U.S. Geological Survey’s ANSS Comprehensive Catalog — about 312,000 events at magnitude 4.5 and above, the oldest of them from 1568. One row per event, revised in place as USGS refines the numbers: magnitude, depth and location all move in the hours and days after an event, and historical entries are re-evaluated decades later, so this dataset follows them rather than freezing the first estimate. Each row also carries the uncertainties the catalogue publishes — horizontal and vertical location error, magnitude error, the station counts behind each — and the networks that actually computed the location and the magnitude.

Attribution, terms and provenanceWhat you must carry if you reuse this

- Notes
- USGS-authored content is in the public domain in the United States and may be reused freely with credit. Two caveats a reuser must read. First, the ANSS Comprehensive Catalog behind this web service aggregates contributions from regional and international seismic networks; an individual event may originate with a contributor whose own terms differ, and the `network`, `location_source` and `magnitude_source` columns name those contributors. Second, this is a living catalogue, not a frozen catalogue of record: recent events carry preliminary automatic solutions, historical events are re-evaluated, values are revised and events are occasionally withdrawn. Do not use it where life or property depends on the number.
