Pu‘u ‘Ō‘ō remains quiet. Clear weather during HVO's August 22 overflight provided good views into the drained crater. Rubble from crater wall collapses has filled in much of the deeper part of the crater, with the bottom now at about 250 meters (820 feet) below the east rim. The curvature of the horizon is caused by the wide-angle view of the camera. USGS video by M.

This video presents an animation of computer-simulated ground motions that might occur for a magnitude 6.9 earthquake rupturing the Rose Canyon fault in southern California. The scenario earthquake ruptures a 65-km-long section of the Rose Canyon fault that lies just offshore of San Diego, California, and Tijuana, Mexico. In this scenario, the rupture starts near the

Clear weather afforded good views of the water pond in Halema‘uma‘u. No major changes were observed in the pond, but the water continues to slowly rise. The water surface was steaming, and its temperature was approximately 70 degrees Celsius (158 degrees Fahrenheit). For scale, the pond is about 70 meters (230 feet) long. USGS video by M. Patrick.

Recorded June 1, 2019 - August 18, 2019: Video shows a series of photos taken every hour during daylight hours in the summer of 2019. The camera looks westward along the coastal bluffs of Barter Island, located on Alaska’s North Slope. A pole on the bluff, visible in the first half of the video, once supported another video camera that was aimed at the

This video shows a close-up of the water pond at the bottom of Halema‘uma‘u on August 13, 2019. Steaming from the water surface shows the shifting winds over the pond.

This video goes into detail about surveying high-water marks, various aspects of bridges, and cross sections for the contracted-opening method. 
 

This video shows a close-up of the ponded water at the bottom of Halema‘uma‘u. USGS video by M. Patrick, 08-09-2019.

This video shows a close-up of the ponded water at the bottom of Halema'uma'u. Yesterday, the separate ponds joined into a single elongate pond. The water level has continued to slowly rise.

Iceland had 269 named glaciers as of the year 2000 but ice has retreated in the face of warming temperatures. By 2014, OK Glacier in western Iceland had lost so much mass that it was no longer considered one at all. Icelanders now refer to it simply as OK, the name of the volcano upon which it rests.
 

This video shows steaming from the main pond of water at the bottom of Halema‘uma‘u as captured on Sunday, August 4. Two smaller areas of ponded water were present a short distance east of this spot. Thermal images indicate that the water surface is roughly 70 degrees Celsius (158 degrees Fahrenheit). USGS video by M. Patrick, 08-04-2019.

Mule deer are an important part of the Western landscape and are coveted among big-game hunters throughout the country. These animals draw outdoor enthusiasts to states, such as Wyoming, where nearly 800,000 people hunted, fished, and viewed wildlife, and contributed $1.1 billion to the state’s economy. Balancing a growing infrastructure in the west that includes housing

This video shows steaming from the main pond of water at the bottom of Halema‘uma‘u as captured on Sunday, August 4. Two smaller areas of ponded water were present a short distance east of this spot. Thermal images indicate that the water surface is roughly 70 degrees Celsius (158 degrees Fahrenheit).

This video discusses the general requirements that will be needed to accomplish a contracted-opening indirect discharge measurement. Approach section, contracted section, and necessary high-water mark locations are described along with scenarios where the method will not be successful. 
 

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

Satellite imagery shows the rupture and shifting of land near Ridgecrest, CA from the July 2019 earthquakes.
 

This video describes how to use SAC-GUI in the field to plot high-water mark profiles. Plotting high-water marks in the field is required for most indirect measurement techniques
 

This video describes the field selection of roughness coefficients, or Manning's "n" values. Both the comparative (photos) and analytical (Cowan's) methods are discussed.
 

This video describes how to survey high-water marks and cross-sections for indirect measurements. Included are tips and tricks for getting across non-wadeable sections of the stream.
 

This video goes into detail about where to flag high-water marks and how to survey a slope-area measurement. A simple one-setup Total Station survey is demonstrated.

This video covers the theory behind a slope-area indirect measurement, the most common type of indirect measurement used in the USGS.
