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.

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.
