Wildfires pose significant threat in an increasingly arid California landscape, threatening life, property, and air quality, and having long-term impacts on the state's water. Knowing the location and extent of wildfire events that effect California may help scientists and resource managers predict and manage potential impacts burns may have upon water quality, availability and movement.

View recent and historical chloride and specific conductance data for active water-quality monitoring stations on streams in Connecticut, Massachusetts, and Rhode Island.

The USGS, the science bureau of the Department of the Interior, conducts wildlife disease surveillance and research to support management of affected species and their habitats. Here you will find information on USGS science addressing Chronic Wasting Disease across the Nation.

Geonarrative that includes summaries of research highlights from the USGS Climate Research & Development Program during 2020.

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.

A geonarrative introducing an integrated approach to improve efficiency and delivery of actionable USGS drought science using advanced information technology.

Since 1969, USGS has collected water-quality data along the deep-channel longitudinal axis of the San Francisco Bay-Delta system at 37 fixed locations spaced 3-6 kilometers apart. The Water Quality of San Francisco Bay Data Query provides access to the entire dataset.

People have been recording seismic activity for centuries. To assemble a detailed earthquake history of an area and understand how faults may behave in the future, however, scientists need to go further back in time—from several hundred to many thousands of years ago.

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.

Learn about how the Climate Adaptation Science Centers have been exploring the topic of ecological drought across the country.

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.
