Earthquake Data Scraper: USGS, EMSC, INGV & More (FDSN)
Pricing
from $0.35 / 1,000 records
Download earthquake lists from USGS, EMSC, INGV, GEOFON, IRIS and other FDSN seismic data centers. Filter by date, magnitude, depth, area or radius; get one row per quake with time, lat/lon, depth, magnitude and place name. Seismic station metadata mode too. Pay per record.
Which FDSN web service to query: event (earthquakes / seismic events) or station (network / station / channel metadata). Both speak the identical FDSN grammar on every data center.
Which seismic data center(s) to query, by name from the fdsn.org registry (case-insensitive; common aliases work — iris, usgs, ingv, geofon, geonet, scedc, ncedc, emsc, isc, auspass…). One name (USGS), a comma-separated list (INGV,GEOFON,EMSC), or all to query every center that offers the chosen service. Leave EMPTY (and leave Service URL empty) to run discovery — list every center + its live service URL. For events, reliable centers include USGS, INGV, GEOFON, EMSC, ISC, GeoNet, SCEDC, NCEDC.
Bypass the registry and point directly at a center's FDSN service — either a full endpoint (https://earthquake.usgs.gov/fdsnws/event/1/query, trailing /query optional) or a bare host (https://earthquake.usgs.gov), for which the standard /fdsnws/{service}/1/query path is built. Overrides Data center. Use this for a center not in the registry, or a private mirror.
When on, the actor ignores the query parameters and only maps the fdsn.org registry — one row per (data center, event|station service) with the center's full name, website and live service URL. This is also the default when both Data center and Service URL are empty. Use it first to discover valid center names, then set Data center to extract.
For the station service only: how much metadata to return — network, station, channel or response. More detail = more columns and more rows (one row per channel epoch at channel level). Ignored for the event service.
The wire format to request for the EVENT service: text (the uniform FDSN pipe-delimited format parsed on every center — recommended) or geojson (richer per-event properties from centers that support it, e.g. USGS and INGV). The station service is always fetched as text (no GeoJSON exists for it). QuakeML/StationXML are never requested — this actor returns flat rows.
FDSN start of the time window (ISO 8601). A bare date (2024-01-01) is expanded to 2024-01-01T00:00:00 automatically (several centers require the full form). For events this bounds origin time; for stations it bounds the metadata epoch.
FDSN end of the time window (ISO 8601). A bare date is expanded to T00:00:00. Keep the window modest for busy catalogs (a global M0+ event query can return millions of rows — combine with Min magnitude and Max records).
Only return events at or above this magnitude. Strongly recommended on wide time windows to keep result counts (and cost) sane. Ignored by the station service.
Only return events at or below this magnitude (event service only).
Southern edge of a rectangular search area, degrees (-90..90). Combine min/max latitude + longitude for a bounding-box search. Works for both event and station.
Northern edge of a rectangular search area, degrees (-90..90).
Western edge of a rectangular search area, degrees (-180..180).
Eastern edge of a rectangular search area, degrees (-180..180).
Latitude of the center point for a radial search. Pair with Longitude + Max radius (and optional Min radius) instead of a bounding box.
Longitude of the center point for a radial search.
Maximum great-circle distance from the center point, in degrees, for a radial search.
Minimum great-circle distance from the center point, in degrees (annular search).
Only return events at or below this depth in kilometres (event service only).
Only return events at or above this depth in kilometres (event service only).
FDSN network code filter for the station service, e.g. IU, IV, NZ. Comma lists and wildcards (* ?) are supported by most centers. Ignored for events.
Station code filter for the station service, e.g. ANMO. Comma lists and wildcards supported. Ignored for events.
Location code filter for the station service (e.g. 00, 10, or -- for blank). Ignored for events.
Channel code filter for the station service, e.g. BHZ, HH?. Comma lists and wildcards supported. Ignored for events.
Sort order for the event service — time, time-asc, magnitude or magnitude-asc (accepted values vary slightly by center). Ignored for stations.
Maximum total number of records to emit across all queried centers (events, stations or discovery rows). Each emitted record is one billable event. The form starts at 3 for a cheap first run; raise it for your own query. If you leave it empty, 25 is used.
Any additional FDSN query parameters as a JSON object, passed straight through, e.g. {"includeallmagnitudes": "true", "eventtype": "earthquake"} for events or {"includerestricted": "false"} for stations. Explicit fields above take precedence. Note: some centers reject certain params (GeoNet rejects limit) and will return their own error.
Optional bearer token for a key-gated / restricted FDSN deployment. Sent as Authorization: Bearer *** — NOT needed for the public centers (USGS, INGV, GEOFON, IRIS, …). Never logged.
