bgs-ogcapi.hazards.earthquake_search
Search UK earthquakes by area (lat/lng + radius), year, and minimum magnitude. Set period to "modern" (default, instrument-recorded since 1970) or "historical" (pre-1970 UK Historical Earthquakes catalogue). Returns event date/time, depth, local magnitude (ML), and intensity.

What bgs-ogcapi.hazards.earthquake_search does on Apibase
AI agents call bgs-ogcapi.hazards.earthquake_search to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
lat | number | — | Decimal degree latitude (WGS84) — must be supplied together with lng. Omit both for full Great Britain coverage. |
lng | number | — | Decimal degree longitude (WGS84) — must be supplied together with lat. |
year | string | — | Filter to a single 4-digit year, e.g. "2020" |
limit | integer | — | Maximum earthquakes to return (default 20, max 100) |
period | string | — | "modern" = instrument-recorded earthquakes since 1970 (default), "historical" = UK earthquakes before 1970 |
radius_km | number | — | Search radius in kilometres around lat/lng (default 50, max 500) |
min_magnitude | number | — | Minimum local magnitude (ML) to include |
