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 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. They surface only briefly to breathe, and rarely come ashore except when females

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

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

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. 
 

Title: USGS Fire Science: Understanding why wildlands burn and what can be done about it

• Wildfires are expensive, dangerous, and have massive impacts on people and ecosystems, yet ecosystems evolved with wildland fire. 
• USGS fire scientists help understand what factors affect wildland fire occurrence, intensity, spread, and effects. 
• What can

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.
 

This video demonstrates how to select an appropriate location for an indirect measurement. Theory and initial reconnaissance are discussed. 

This video shows how to survey a slope-conveyance indirect measurement using a conventional optical or digital level. 
 

This video details how to measure various aspects of a box culvert for a culvert indirect measurement. The video includes tips and tricks for measuring the geometry, wingwall angles, and entrance types including rounded or beveled entrances.
 

This video provides an introduction to the slope-conveyance method of indirect measurement. Theory and background are described as well as high-water mark and cross-section placement. 
 

Tribes have been actively engaged in efforts to anticipate and respond to climate impacts on their natural and cultural resources. And yet, some tribes have faced difficulties initiating and completing the critical first step of the climate adaptation planning process: an assessment of locally-specific climate risks that accounts for the unique priorities, values, and

This video provides basic information about the HydroLink Tool to get you up and running with the basic tool capabilities.
 

This animation takes the viewer down the Glen Canyon from Bullfrog Bay to the Rincon, in the Glen Canyon National Recreation Area. New high resolution multibeam bathymetry collected by the USGS in 2018 shows the submerged portions of Glen Canyon. 
 

The Marsh Arabs of southeastern Iraq have spent millennia traversing the waterways at the confluence of the Tigris and Euphrates rivers. The recent history of those wetlands, however, has been one of forced loss and uneven recovery. 

The marshes once stretched across nearly 5,800 square miles. This Landsat 5 image from 1986 shows lush vegetation and dark waters both

This is an animation showing the changing conditions of USGS streamgages from January 1, 2019 to June 1, 2019. The conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). There is also a purple ring added to indicate gages that are flooding. During the animation, three locations in TN broke record water

Title: New Mapping of the Rodgers Creek Fault: It's longer and more complex than we thought

• Remote sensing technology reveals surface traces of the fault covered by trees and buildings.
• Greater fault length and linkages to neighboring faults make larger earthquakes possible. 
• Fault complexity has implications for hazards from ground shaking
