This is b-roll footage of a ShakeAlert earthquake early warning system seismic station. These seismic stations and sensors are deployed around California and are used to monitor earthquake activity.
 

Science is done by those who "do." Thank you women in science for all your contributions to USGS and the sciences, as a whole.
 

Before landing on the surface of the moon in 1969, astronauts Neil Armstrong and Buzz Aldrin needed a training ground that matched their destination's cratered surface.

Wildlife passages are one tool used to help amphibians and reptiles cross roads safely. Barrier fencing along the road and "turn-arounds" help guide these animals towards the passageways. In this video, a western toad hops back towards the passage after reaching a turn-around structure, following the barrier fencing.
 

This animation shows preliminary results from precise relocation of the Ridgecrest earthquake sequence, through July 6 (UTC), including the foreshock sequence and the first ~20 hours of aftershocks from M 7.1 mainshock.  The animation begins in a map view and then transitions into a rotating vertical slice.  Earthquakes are colorcoded by time of occurrence

This animation shows preliminary results from precise relocation of the Ridgecrest foreshock sequence, up to the the time of occurrence of the M 7.1 mainshock.  The animation begins in a map view and then transitions into a rotating vertical slice.  Earthquakes are colorcoded by time of occurrence, with early events in dark blue and later events (up to the

A Landsat satellite image captured the flooding in Dell Rapids, SD in the Spring of 2019. It's remarkably similar to an aerial photograph of flooding 50 years earlier. 

 

This video shows Moku‘āweoweo, the caldera at the summit of Mauna Loa, during a routine overflight. The flight path goes from northeast to southwest, and begins at North Pit crater before crossing over the main caldera floor. In the southwest portion of the caldera floor, the 1940 and 1949 cones can be seen.

This video shows the earthquake events a few hours before the M6.4 on July 4th, 2019 till after the M7.1 on July 8th, 2019. The blue dots are the events associated with the M6.4 and then red dots are events associated with the M7.1

This video demonstrates use of the Digital Shoreline Analysis System (DSAS) v5.0 to produce rates of shoreline change. For more information please visit the DSAS project page: https://woodshole.er.usgs.gov/project-pages/DSAS/ 

This video reviews the requirements and instructions for installing the Digital Shoreline Analysis System (DSAS) v5.0. For more information please visit the DSAS project page: https://woodshole.er.usgs.gov/project-pages/DSAS/ 

This video describes the high-water marks needed along with cross-section locations for critical depth indirect measurements. Critical depth computations are those performed when flow goes through a critical flow regime at a drop, such as at a waterfall. 
 

This video describes the survey requirements for culvert indirect measurements, specifically how to measure various aspects of the culvert itself. This video provides a general overview of how to survey culvert attributes, such as the invert and length.
 

See St. Joseph Bay in the Florida Panhandle through the eyes of two young adult female loggerheads as they swim, surface to breathe, dive, forage on underwater grasses and spend time with other sea turtles. Three species of threatened or endangered sea turtles congregate in St. Joseph Bay.

Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, describes activity at Yellowstone during the month of June, 2019.

 

This video discusses how to measure various aspects of non-standard culverts, such as mitered culverts. Using the slope-area method inside a culvert is also discussed. 
 

This video details how to survey indirect measurements with GNSS. Both RTN and RTK setups are discussed, along with tips and tricks and troubleshooting.

National Hydrography Advisory Call:

This video describes the survey requirements for culvert indirect measurements, including high-water mark and cross-section locations. 
 

This video demonstrates how to measure various aspects of pipe and pipe-arch culverts for culvert indirect measurements. The video includes tips and tricks for measuring the geometry, corrugations, and entrance types including rounded or beveled entrances.
