Final answer:
The USGS is responsible for natural hazard disclosures for earthquake fault zones, seismic hazard zones, and dam failure inundation areas as it is the agency that deals with scientific information related to natural hazards.
Step-by-step explanation:
The primary responsibility to make natural hazard disclosures for earthquake fault zones, seismic hazard zones, and dam failure inundation areas is with the United States Geological Survey (USGS). The USGS is a US government agency that provides scientific information about natural hazards, the natural resources we rely on, and the health of our ecosystems and environment. They also monitor and report on the impacts of climate and land-use change. This involvement with various aspects of earth science places the USGS in the appropriate position to disclose information regarding geological hazards and areas of potential concern.
