search_earthquakes
ActiveTool of usgs-earthquakes
Search the USGS earthquake catalog (FDSNWS event API) for real-time and historical seismic events. Filter by time window, magnitude, depth, and a circular geographic area. Returns a compact list of quakes with magnitude, location, time, coordinates, depth, and significance. Keyless.
