Earthquake API

healthy 3,580 Subscribers

Real-time and historical earthquake data sourced from the USGS Earthquake Hazards Program. Pull ready-made summary feeds by magnitude band and period (significant, M4.5+, M2.5+, M1.0+ or all, over the past hour, day, week or month), run a full FDSN search by time window, magnitude range and geographic radius, count matching events, fetch the latest quakes worldwide, or look up a single event by its USGS id. Every event comes as a clean record with magnitude and type, place, ISO timestamps, depth and coordinates, felt reports, shaking intensity (CDI/MMI), PAGER alert level, tsunami flag and significance. Authoritative public data delivered through a fast, reliable API — ideal for insurance and risk, IoT and sensor alerting, newsrooms, research and disaster-response apps.

Earthquake Magnitude API

Earthquake-magnitude seismology as an API, computed locally and deterministically. The energy endpoint computes the radiated seismic energy released by an earthquake of a given magnitude using the Gutenberg-Richter relation, log10(E) = 1.5·M + 4.8 with E in joules, and converts it to a TNT equivalent in tons and kilotons (one ton of TNT ≈ 4.184×10⁹ J), with a felt/damage classification. The compare endpoint quantifies how much bigger one quake is than another: each magnitude unit means about ten times the ground-motion amplitude on a seismograph and about 31.6 times (10^1.5) the energy, so it returns both the amplitude ratio and the energy ratio between two magnitudes. The moment-magnitude endpoint converts between the seismic moment M0 (in newton-metres, M0 = rigidity × rupture area × slip) and the moment magnitude with the Hanks-Kanamori relation Mw = (2/3)·log10(M0) − 6.07, in either direction. Magnitudes are dimensionless, energy is in joules and seismic moment in newton-metres. Everything is computed locally and deterministically, so it is instant and private. Ideal for seismology-education, disaster-modelling, insurance, structural-risk and science app developers, earthquake-energy and magnitude tools, and STEM teaching. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is the earthquake-magnitude calculator; for real-time and historical earthquake event feeds use an earthquake data API.

USGS Streamflow API

Live river and stream conditions from the USGS Water Services network. The catalogue of 16,900+ active US streamflow gauges is searchable by name, state or coordinate; the live endpoint returns the latest observation for any gauge: streamflow / discharge (in cubic feet per second and m³/s) and gauge height (in feet and metres), with the station name, observation time and coordinates. Find the gauges nearest any lat/lon. Ideal for flood monitoring, hydrology, whitewater/fishing & recreation apps, drought tracking and environmental dashboards.

Volcanoes API

The Smithsonian Global Volcanism Program (GVP) Holocene volcano list as an API — 1,215 volcanoes active within the last ~10,000 years. Look up any volcano by its GVP number (e.g. 211020 → Vesuvius) or name; search by name, country, type or region; or find every volcano within a radius of any coordinate (great-circle distance). Each record carries the volcano type, last-known eruption year, country/region, latitude/longitude, summit elevation, tectonic setting and a geological summary. Ideal for natural-hazard dashboards, travel/geography apps, education and earth-science tooling.

OpenStreetMap Community API

Live OpenStreetMap community and contribution data as an API — the people and the edits behind the collaborative free world map, served from the official OSM API. Look up any mapper by their user id for their profile (display name, account age, total changesets and GPS traces, roles), pull a user's recent changesets — each edit batch with its comment, the editor used, and how many map features it created, modified or deleted — or read the open and resolved map notes, the community feedback pins, inside a geographic bounding box. The OSM contributor-and-edits layer for mapping, community and dashboard apps. Live, no key. Distinct from geocoding, routing and map-tile APIs that merely consume OpenStreetMap data — this is the OSM community and editing activity itself.

Frequently asked questions

Quick answers about pricing, quotas, and integration.

How do I get an API key for Earthquake API?

Sign up for free at oanor.com, generate an API key from the developer dashboard, and call Earthquake API with the x-oanor-key header. No credit card needed for the free tier.

What's the rate limit for Earthquake API?

Free tier allows 1 request per second. Paid plans scale up to 50 requests per second on the Mega tier. Hard limits return HTTP 429 above the quota — no surprise overage charges.

How much does Earthquake API cost?

Earthquake API has a free tier with 100 calls / month. Paid plans start at €12.00 / month with higher quotas and faster rate limits.

Can I cancel my subscription anytime?

Yes. Plans are billed monthly and you can cancel anytime from your billing dashboard. No long-term contracts and no cancellation fee.

Is Earthquake API GDPR-compliant?

All requests to Earthquake API go through our EU-based gateway. Your upstream API key never leaves our server and no personal data is shared with the upstream provider beyond the request you send.
