The Big Thompson Floods of 1976 and 2013 shown visually. The inundation images reflect the location and peak streamflows at certain points between Estes Park and Loveland, Colorado.
Starting in 2011, the National Park Service removed two obsolete dams from the Elwha River in Olympic National Park, Washington. It was the world’s largest dam-removal project. Over the next five years, water carrying newly freed rocks, sand, silt and old tree trunks reshaped more than 13 miles of river and built a larger delta into the Pacific Ocean.
The atypical location of Mount St. Helens may be due to geologic structures that control where deep magmas can rise through the crust, as suggested by new findings published today in Nature Geoscience.
Researchers from NOAA, U.S. Geological Survey and their partners have completed the first high-resolution, comprehensive mapping of one of the fastest moving underwater tectonic faults in the world, located in southeastern Alaska. This information will help communities in coastal Alaska and Canada better understand and prepare for the risks from earthquakes and tsunamis that can occur when faults suddenly move.
Twenty-five middle-school girls from Washington and Oregon are participating in the fourth annual “GeoGirls” outdoor volcano science program at Mount St. Helens, jointly organized by the U.S. Geological Survey and the Mount St. Helens Institute.
Lower levels of environmental contaminants—including pesticides, flame retardants and other pollutants—were recently found in osprey eggs in the Delaware Estuary compared to those tested from the 1970s through the early 2000s.
This Thursday, scientists with the U.S. Geological Survey and NASA will test new technologies near Parkdale, Colorado, located west of Cañon City, to better understand how unmanned aerial systems (UAS), or drones, may be used to measure water depth, water levels and velocity from the sky.
Magnetic measurements made during low-altitude airplane flights conducted for the U.S. Geological Survey and the Oklahoma Geological Survey reveal possible deep faults that may contribute to increased seismic activity in response to wastewater injection in certain portions of Oklahoma.
Now through late July, 2018, U.S. Geological Survey scientists will conduct fieldwork on public lands in Phillips and Valley counties near Malta and Glasgow, Montana, as part of a grassland bird project.
MEDIA ADVISORY
Have you ever wondered what scientists do at a volcano observatory when a volcano is not erupting? There is plenty to accomplish—probably more than you can imagine.
May is Volcano Preparedness Month in Washington, providing residents an opportunity to become more familiar with volcanic risk in their communities and learn about steps they can take to reduce potential impacts.
Real-time water-quality, streamflow and water height information for Lake Houston and the surrounding San Jacinto watershed are now available from a new web application from the U.S. Geological Survey, done in cooperation with the City of Houston.
