Many of the earthquakes in Hawaii that extend offshore and up the island chain are due to plate bending, or flexure. The upper panel shows magnitude-5 and greater earthquakes since 1861, with some notable events labeled.

USGS Hydrologic technician Sarah Davis measuring streamflow at the South Fork Grand River near Cash, SD (streamgage 06356500) on January 31, 2019. Measuring the streamflow under ice requires drilling holes across the width of the stream and then collecting data from each hole. At times streams can freeze solid but drilling holes are necessary to verify t

Root nodules are a symbiotic relationship between a plant and nitrogen-fixing bacteria. A symbiotic relationship is one where both organisms benefit. Nitrogen-fixing bacteria change inorganic nitrogen from the air into ammonia, a form of nitrogen most organisms can use.

USGS geologists are conducting field work at the summit today to make observations of volcanic ash and measure volcanic gas. This photograph is taken on Crater Rim Drive where the road intersects the Southwest Rift Zone. Rockfall dust and volcanic ash covers the ground and cracks in line with the Southwest Rift Zone trace traverse the pavement.

This video is an introduction to the partnership between the USGS Arizona Water Science Center and the Arizona Department of Transportation, or ADOT, as it is referred to throughout the video. These two agencies are working together, using cutting edge technology and methods, to understand how flood flows interact with and impact critical infrastructure.
