Earthquake Tour of Santa Rosa, California

This geonarrative (Esri Story Map) takes you on a virtual tour of 1906 and 1969 earthquake damage in Santa Rosa, shows examples of buildings that have been retrofitted to protect against future earthquake shaking, and highlights locations where faulting from large earthquakes and slow fault slip (creep) is expressed at the ground surface. 

Emergency Assessment of Post-Fire Debris-Flow Hazards: Dolan Fire

This interactive map depicts the likelihood of debris-flow generation and estimates of flow magnitude in locations where debris flows initiate. The models do not predict downstream impacts, potential debris-flow runout paths, and the areal extent of debris-flow or flood inundation.

2020 Year in Review story map

Our scientists work with State fish and wildlife agencies and Federal natural resource agencies, providing them with the science used in management decisions to support sustainable fish and wildlife populations, thus helping to maintain biodiversity, address climate change, and enhance wildlife watching and sustainable use. 

USGS Fluvial Erosion Hazards (FEH) Primer

This primer highlights methods used in regional and reach-scale assessments of fluvial erosion hazards (FEH)Fluvial erosion includes bed erosion, meaning lowering of the bed of a stream, as well as bank erosion, which refers to the retreat of stream banks that occurs as a stream widens or migrates laterally.

Surface Water Flow Trends in the Nation's Streams and Rivers

Changes in streamflow conditions can affect infrastructure, water supply, and ecosystems. The IWAAs Surface Water Flow Trends mapper provides access to information about long-term changes in low flows, mean flows, and peak flows. View national trends for the last 100, 75, or 50 years, or calculate trend values for a custom time period at an individual site.

Future Coastal Flooding

Prediction of Flooding Now and Into the Future: a geonarrative on coastal storms

Hydrogeology of the Adelaida Area, San Luis Obispo County, CA

The USGS is conducting a comprehensive evaluation of groundwater resources of the Adelaida area. Use this map to explore the hydrogeology of the area, including land use, geology, and USGS hydrologic data by watershed or water management district. 

TrendPowerTool: A web lookup tool for estimating the statistical power of a monitoring program to detect population trends

A simulation-based power analysis can be used to estimate the sample sizes needed for a successful monitoring program, but requires technical expertise and sometimes extensive computing resources. We developed a web-based lookup app, called TrendPowerTool.

Arctic Research and Policy Act Boundary Map: Circumpolar

All US and Foreign territory north of the Arctic Circle and all US terrritory north and west of the boundary formed by the Porcupine, Yukon, and Kuskokwim Rivers; all contiguous seas including the Arctic Ocean and the Beaufort, Bering and Chukchi Seas, and the Aleutian chain.

Arctic Research and Policy Act Boundary Map: Bering Sea

All US and Foreign territory north of the Arctic Circle and all US terrritory north and west of the boundary formed by the Porcupine, Yukon, and Kuskokwim Rivers; all contiguous seas including the Arctic Ocean and the Beaufort, Bering and Chukchi Seas, and the Aleutian chain.

Arctic Research and Policy Act Boundary Map: Alaska Terrestrial

Region: Alaska.  All US and Foreign territory north of the Arctic Circle and all US terrritory north and west of the boundary formed by the Porcupine, Yukon, and Kuskokwim Rivers; all contiguous seas including the Arctic Ocean and the Beaufort, Bering and Chukchi Seas, and the Aleutian chain.

Coastal Change in Alaska

Alaska's north coast has been home to indigenous communities for centuries. Changing coastlines threaten important infrastructure and historic sites that support indigenous communities. Changing coastlines also can potentially reduce habitat for Arctic wildlife, such as polar bears, shorebirds, and walruses.
