The video describes USGS efforts to improve lahar (mudflow) monitoring at Mount Rainier, an ice-clad volcano in Washington State with potential for dangerous volcanic mudflows. The presentation was given to colleagues in the US and in Ecuador by Andy Lockhart.

Reflections on the Ridgecrest earthquake sequence one year after from a few USGS employees. Employees discuss when they first heard about the magnitude 6.4 and notable professional experiences that happened afterwards.
 

This video describes USGS use of Unoccupied Aircraft Systems (UAS) or "drones" for use in 2018 at Kilauea Volcano in Hawaii. The speaker, Angie Diefenbach, is a leading expert in use of UAS for volcano surveillance and research. The presentation was given in June 2020 to colleagues in Ecuador who are interested in applications of UAS at their volcanoes.

In a remote part of the Sahara Desert in Egypt, center pivot irrigation fields fill the landscape. Thanks to the Landsat archive, we can see how dramatically this area has changed over the last 35 years. But until the growth in irrigation, this part of the world hadn't changed much from a satellite's perspective.

This video describes Step 2 of the Land Treatment Exploration Tool. In Step 2 the user defines their planned treatment boundary. The user can load a zipped shapefile or on-screen digitize their boundary.  

This video describes Step 3 of the Land Treatment Exploration Tool. In Step 3 the user is guided to the Site History tab to explore land treatment and wildfire history of their planned treatment area.

This video describes Step 5 of the Land Treatment Exploration Tool. In Step 5 the user determines a distance or boundary to search for legacy Land Treatment Digital Library records. The user also indicates if the returned LTDL treatments are statistically evaluated against the planned treatment boundary using a Bray-Curtis Dissimilarity calculation.

This video describes Step 6 of the Land Treatment Exploration Tool. In Step 6 the user filters through the returned list of legacy LTDL treatments to identify records that contain useful information or context for the current planned treatment boundary. Selected treatments are added to the developing report and subsequent exported Site Characterization PDFs.

This is a quick introduction video to the Land Treatment Exploration Tool. This short video includes a summary of the tool with screen clips of the fact sheet, web tool, and an example Site Characterization Report.

This video describes Step 4 and the developing report of the Land Treatment Exploration Tool. In Step 4 the used selects layers to generate spatial overlap statistics with their planned treatment boundary. Summary tables are generated and displayed in the Report tab, where a user can create a PDF Site Characterization Report for their planned treatment boundary.

This video describes Step 1 of the Land Treatment Exploration Tool. In Step 1 the user defines a name, the planned treatment/s, and a file name for exported items.

The Landsat series of Earth-observing satellites has been continuously acquiring land surface imagery since 1972. Over 10 million Landsat scenes are currently available for download. They are also accessible from a cloud environment, in a cloud optimized format that gives you more flexible, customized access.

This wide-angle video was captured during a helicopter overflight on May 29, and skirts the southern border of Halema‘uma‘u crater. The water lake, filling the bottom of the crater, was tan and brown today, and showed no significant changes. USGS video by M. Patrick.

A helicopter overflight provided aerial photographs of Kīlauea caldera on May 29, and these photos were used to construct a 3D model. The water lake is visible as the tan area in the deepest portion of Halema‘uma‘u crater. For scale, the water lake is 270 m (885 ft) long and approximately 600 m (1970 ft) below the western caldera rim. USGS photos by K. Mulliken.

Mike Poland, Scientist-in-Charge of the Yellowstone Volcano Observatory, gives an overview of activity at Yellowstone during May 2020.

 

Do you have what it takes to be a bat biologist? USGS bat researchers are counting Townsend’s big eared bats to monitor how their populations are doing. Watch the video to try your hand at a bat count and see how your skills compare to a USGS scientist!

This video discusses how adhesion and cohesion work together to create capillary action! There is an experiment at the end of the video to demonstrate this as well! If you would like to do the experiment with us you will need: 1) Coffee filter 2) Washable marker 3) Glass of water

A small rockslide occurred today on the south wall of Halema‘uma‘u, sending boulders into the water at the bottom of the crater. USGS video by M. Patrick.

London Bridge was indeed falling down. Set to be torn apart and replaced in the 1960s, this bridge across the River Thames was purchased by businessman Robert McCulloch in April 1968 and shipped across the Atlantic, to Lake Havasu City, Arizona, billed as the world's largest antique.

Surface tension performs many duties that are vitally important to the environment and people. This video briefly covers Surface tension.
