New study reveals insights into Yellowstone Volcanic System’s Hidden Magma Reservoirs
HILO, Hawaii — Researchers from the U.S. Geological Survey and Oregon State University examined the area beneath Yellowstone Volcanic system finding that although an eruption is unlikely anywhere in the area, changes to the northeast area of the volcanic system will be the key to understanding future eruptions. Scientists at USGS mapped underground areas containing magma in this volcanic system. Understanding where magma is located is essential for predicting volcanic activity and keeping the public informed about potential risks. This study gave a clear picture of how magma is distributed through the crust at Yellowstone using a method that is most sensitive
Remote-Sensing Large-Wood Storage Downstream from Reservoirs After Dam Removal
In a new USGS-led study, scientists have leveraged cutting-edge remote sensing and Artificial Intelligence (AI) technology to measure the movement and storage of large wood along the Elwha River in Washington State. This research, which followed the historic removal of two major dams on the river, provides new insights into how natural materials like wood and sediment shape river ecosystems over time. Researchers relied on aerial imagery collected from 2012 to 2017 as part of interdisciplinary before-after/control-impact studies of dam-removal response. The images were generated using structure-from-motion photogrammetry using a digital camera mounted in the wing of a small airplane.
