This resource discusses the distribution of water on Earth's surface, in soil moisture and groundwater, and in the atmosphere. Charts and graphs summarize total water withdrawals from surface and ground sources, and provide an estimate of global water distribution, in cubic miles and cubic kilometers, from all known sources. Links to additional information are embedded in the text. Full description.

This database summarizes geologic, geomorphic, and geographic information for about 2,000 Quaternary faults and folds in the United States. These structures are believed to be sources of magnitude 6 or greater earthquakes during the Quaternary Period (the past 1,600,000 years). Maps of these geologic structures are linked to detailed descriptions, including geologic setting, fault orientation, fault ... Full description.

This preliminary assessment of urban growth in the Central Valley of California is intended to illustrate the dramatic changes to the Central Valley landscape over the past 100 years. Data products include an urban growth timeline for the years 1900 to 1996, an animated version of the same timeline, and graphs showing the increase in population and built-up land for the same period.

This map shows Earth's tectonic features, volcanoes, earthquakes, and impact craters. Smaller inset maps are included to depict the North and South Poles. The back of the map provides additional information, highlighting examples of fundamental processes; and providing text, timelines, references, and other resources to enhance understanding. The main and polar maps feature online interactive versions. ... Full description.

This interactive map allows users to find their local watersheds and access a variety of information on conditions in them. Search hierarchy is based on region (the largest), subregion, accounting unit, and hydrologic unit (the smallest). The information includes streamflow data (real-time and archived), water quality data, water use data, groundwater sites by county, and links to regional studies ... Full description.

This map shows debris flow hazard areas in the United States, including locations of known debris flows and predictions of where future flows might occur. It shows the locations of debris flows in two different ways, as points representing the locations of individual flows or small groups of flows, and as areas or polygons containing one or more debris flows. Different symbols are used to indicate ... Full description.

This interactive map shows landslide hazard areas of the United States. Users can click on selected areas of the map (marked by circles) to view more detailed enlargements. The map is color-coded; areas of high landslide incidence or susceptibility are colored pink or red. It is accompanied by an open-file report that provides an overview of the study. There are also links to shapefiles of the landslide ... Full description.

This site describes the distribution and movement of water around, through, and above the Earth as water vapor, liquid water, and ice, with emphasis on the water cycle (hydrologic cycle). A summary data table provides an estimate of global water distribution in cubic miles and kilometers from all sources (oceans, ice caps, groundwater, lakes, etc.). There is also a link to a water cycle graphic available ... Full description.
