USGS Earthquake Data Scraper — FDSN Event Feed

Query USGS's public FDSN earthquake catalog by time window, magnitude, depth, bounding box, or radius and export flat, typed rows — magnitude, location, depth, significance, alert level, tsunami flag, and felt reports — no raw GeoJSON to hand-parse.

What this Actor scrapes

USGS's public FDSN event web service (earthquake.usgs.gov/fdsnws/event/1/query) — the same catalog that feeds USGS's own earthquake map. Every event in scope carries magnitude, exact location, depth, significance score, PAGER alert level, tsunami flag, and community felt-report data (CDI/MMI), flattened into one typed row.

What we handle for you

Full FDSN parameter surface — magnitude, depth, and time filters,
Every risk field on every row — alert, tsunami, sig, felt,
Flat, typed output — a fixed schema (event_id, magnitude,

Input

Paste this into the Apify Console, or send it as the run input over the API. Proxy settings are on by default; you rarely need to touch them.

Field	Type	Required	What it does
`starttime`	string	yes	Earliest event time (inclusive). Accepts YYYY-MM-DD or full ISO-8601, passed through to USGS unchanged.
`endtime`	string	yes	Latest event time (inclusive). Accepts YYYY-MM-DD or full ISO-8601, passed through to USGS unchanged.
`minmagnitude`	number	no	Only events at or above this magnitude.
`maxmagnitude`	number	no	Only events at or below this magnitude.
`mindepth`	number	no	Only events at or below this depth in kilometers (deeper = larger value).
`maxdepth`	number	no	Only events at or above this depth in kilometers.
`minlatitude`	number	no	Bounding-box filter. Must be set together with Max latitude, Min longitude, and Max longitude — all four or none.
`maxlatitude`	number	no	Bounding-box filter. Must be set together with Min latitude, Min longitude, and Max longitude — all four or none.
`minlongitude`	number	no	Bounding-box filter. Must be set together with Min latitude, Max latitude, and Max longitude — all four or none.
`maxlongitude`	number	no	Bounding-box filter. Must be set together with Min latitude, Max latitude, and Min longitude — all four or none.
`latitude`	number	no	Radius-search center. Must be set together with Center longitude and Max radius (km) — all three or none.
`longitude`	number	no	Radius-search center. Must be set together with Center latitude and Max radius (km) — all three or none.

FAQ

Can I combine a bounding box and a radius search in the same run?

No — USGS treats them as alternative location filters, so set one or the other, not both, in a single run.
