Source agencies

  • NOAA National Centers for Environmental Information (NGDC) - Public Domain (U.S. Government) (Primary upstream. Significant Earthquakes database with historical damage and casualty records.)
  • U.S. Geological Survey - Public Domain (U.S. Government) (Real-time and recent earthquake catalog merged with NOAA NGDC for recent coverage.)
  • Natural Resources Canada - Earthquakes Canada - Open Government Licence - Canada (Canadian earthquake catalog merged into the canonical earthquake lane after fuzzy deduplication against the existing blended source. Adds dense local Canadian coverage and labeled non-tectonic seismic rows via event_subtype.)
