Search recent earthquakes worldwide by minimum magnitude, a region (radius around a latitude/longitude), or USGS PAGER estimated-impact level. Get back magnitude, location, depth, tsunami flag, and a link to the full USGS event page — most recent first.
Built for catastrophe/insurance risk teams, logistics and supply-chain monitoring, and disaster-response coordination watching a specific region.
Input
{"latitude": 34.0522,"longitude": -118.2437,"radiusKm": 300,"minMagnitude": 4.5,"alertLevel": "all","daysBack": 7,"maxResults": 25}
| Field | Type | Description |
|---|---|---|
latitude / longitude | number | Center point for a regional search. Leave both blank for a worldwide search. |
radiusKm | number | Search radius around the center point, in km. Only used with latitude/longitude. Default 300. |
minMagnitude | number | Only return earthquakes at or above this magnitude. Default 4.5. |
alertLevel | string | USGS PAGER estimated impact: all, green, yellow, orange, or red. Most earthquakes have no alert level — leave all unless specifically hunting for significant events. |
daysBack | number | How many days back from today to search. Default 7, max 365. |
maxResults | number | Max earthquakes to return, most recent first. Default 25, max 100. |
Output
One record per earthquake:
{"eventId": "us6000tjqj","magnitude": 5.1,"magType": "mb","place": "232 km SSW of Pagar Alam, Indonesia","time": "2026-08-10T17:08:06.809Z","alertLevel": null,"tsunami": false,"felt": null,"cdi": null,"significance": 400,"status": "reviewed","depthKm": 21.72,"latitude": -5.9347,"longitude": 102.3607,"url": "https://earthquake.usgs.gov/earthquakes/eventpage/us6000tjqj"}
How it works
Direct calls to the official USGS Earthquake Hazards Program FDSN event API — the same data source behind USGS's own earthquake maps. No API key, no proxy, no login, no scraping.
Pricing note
Billed per search, not per earthquake returned — one charge whether the search returns 1 event or 100.
