Sea-Level Rise Hazards and Decision Support- Coastal Wetlands

Coastal wetlands are among the most productive ecosystems in the world. These wetlands at the land-ocean margin provide many direct benefits to humans, including habitat for commercially important fisheries and wildlife; storm protection; improved water quality through sediment, nutrient, and pollution removal; recreation; and aesthetic values. These valuable ecosystems will be highly...

Geologic Mapping Offshore of Rhode Island

The U.S. Geological Survey (USGS), in cooperation with the National Oceanic and Atmospheric Administration (NOAA), is mapping sea-floor geology and sedimentary environments offshore of Rhode Island. This site provides links to bathymetric, sidescan-sonar, sediment, photographic, seismic-reflection, and interpretive datasets, all presented in Geographic Information System (GIS) formats and...

Early Warning System

Once the smoke clears from a wildfire, the danger is not over!! Other hazards, such as flash floods and debris flows, now become the focus. Areas recently burned by wildfires are particularly susceptible to flash floods and debris flows during rainstorms.

Emergency Assessment of Post-Fire Debris-Flow Hazards

Estimates of the probability and volume of debris flows that may be produced by a storm in a recently burned area, using a model with characteristics related to basin shape, burn severity, soil properties, and rainfall.

Wildfire can significantly alter the hydrologic response of a watershed to the extent that even modest rainstorms can produce dangerous flash floods and debris flows....

A Possible Cause of Earthquakes in the Continental Interior

Release Date: JUNE 18, 2018

A new map of crustal stress across the U.S. shows that the plate interior stress is variable, with contributions from plate boundary stress, crustal collapse due to gravity, and more local and subtle changes to style, orientation, and earthquake rate.

Mountain Permafrost, Climate Change, and Rock Avalanches in Glacier Bay National Park, Alaska

Release Date: JUNE 18, 2018

We usually hear about landslides and avalanches that are caused by large amounts of rainfall, the shaking from earthquakes, or a volcanic eruption, but we may be hearing more about avalanches caused by the (seemingly innocuous) melting of ice in the coming years.
