From the main USGS page, you can select information by state or search the site. There are also convenient links to newsworthy information on earthquakes, volcanoes, and other hazards. An enormous amount of map, graphic, and textual information is available online through their Maps, Imagery, & Publications portal.

The agency covers the following broad science areas, which each have their own website:

  • Climate & Land Use Change: Monitoring changes in the land and studying connections between land and people
  • Ecosystems: Wildlife monitoring, global change research, and other areas, such as taxonomy and land use studies
  • Energy, Minerals, and Environmental Health: Study of mineral and energy resources, including the economic and environmental effects of their extraction and use 
  • Natural Hazards: Studies and warnings related to earthquakes, volcanoes, landslides, floods, etc.
  • Water Resources: Monitoring and research on hydrology and water quality, including maps and information on projects and events

Geologic maps are an important resource for studying Earth Science. USGS' National Geologic Map Database is a portal to thousands of maps and related information.

You can find information on more topics by browsing the "Science Topics" page. And they have a special Geoscience Data Catalog page that provides links to data produced by the USGS, by series title and geographic location.
