USGS Query Earthquakes

Query the USGS FDSN earthquake database with custom parameters to search historical and recent seismic events. Filter by magnitude, time range, location (bounding box or radial search), and depth. Returns detailed GeoJSON for all matching earthquakes. Useful for historical seismicity analysis, regional earthquake studies, and risk assessment.
