How this service works
Bounded filtered USGS FDSN earthquake data with source receipts, UTC and coverage; not a risk forecast. Possible capped results are partial and not charged; no forecast or global completeness claim.
Output
Returns a GeoJSON FeatureCollection of earthquake events matching the query filters, where each feature includes event geometry (longitude, latitude, depth), magnitude, event time, place description, and USGS event ID. The response envelope wraps this in an ok/result structure.
Example use cases
Regional seismic risk scoring for insurers
“Get me all earthquakes of magnitude 5.0 or higher that occurred in the Pacific Northwest between March 1 and March 31 2024 in GeoJSON format — I need this to update our insurance hazard scores.”
Infrastructure safety monitoring after major quake
“Can you pull every earthquake above magnitude 4.0 from the USGS catalog between April 3 and April 10 2024 so our engineering team can assess bridge and pipeline exposure in the affected region?”
Academic seismicity research dataset
“I'm doing research on aftershock sequences — fetch all seismic events with magnitude 3.0 or above from February 6 to February 28 2023 in GeoJSON format for the Turkey-Syria region.”

Endpoint
POSThttps://usgs-earthquake-query.hergertsynthora.com/service?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need richly filtered earthquake data beyond what a static RSS or Atom feed provides — specifically when filtering by magnitude threshold, custom time windows, or spatial bounding boxes is required. It is ideal for autonomous agents doing seismic risk scoring, insurance underwriting, infrastructure hazard analysis, or research pipelines that need machine-readable GeoJSON rather than human-readable feeds. Prefer this over the standard USGS public feed when programmatic, parameterized access with per-call pricing is acceptable.
Side effects
- Invalid or missing starttime/endtime causes query rejection
- Magnitude value out of accepted USGS range returns empty or error result
- Overly broad time range or low magnitude threshold may time out or return excessively large payloads
- Malformed format parameter causes response format error
- Network or upstream USGS FDSN service downtime yields a failed or empty result
