This sequence captured on August 31 begins with a close-up of the fumaroles on the north side of Halema‘uma‘u, then shows a broader view of the crater with the water pond at the bottom and a close-up of steaming and ripples on the water surface. USGS video by M. Patrick, 08-31-2019.

Another day of clear weather provided good views of the water pond in Halema‘uma‘u at Kīlauea's summit. No significant changes were observed, and the thermal camera showed the water surface is still about 70 degrees Celsius (158 degrees Fahrenheit). USGS video by M. Patrick.

Daytime and nightime imagery from Earth-observing satellites reveal dramatic changes in North Dakota during the Bakken oil boom.

 

During Aug. 4-8, 2019, U.S. Geological Survey women scientists, university researchers and Mount St. Helens Institute staff led 25 middle-school girls from Washington and Oregon in the fifth annual “GeoGirls” outdoor volcano science program at Mount St. Helens, Washington.
 

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.

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.

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.

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. 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.

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.
