http://gallery.usgs.gov/videos/811 This video was edited and compiled from raw footage recorded by a camera equipped radio collar that was put on a female polar bear in the Beaufort Sea during April 2014 by the US Geological Survey. This new type of camera technology was developed by videographer Adam Ravetch with the support of the World Wildlife Fund. The video, which is the first ever from a free-ranging polar bear on Arctic sea ice, shows an interaction with a potential mate, playing with food, and swimming at the water's surface and under the sea ice. These videos will be used by the US Geological Survey in research to understand polar bear behavior and energetics in an Arctic with declining sea ice. Note: Some creative license has been taken to make this footage easier to follow and understand, including playful language that helps describe the polar bear's actions.
http://gallery.usgs.gov/videos/628 The rapid onset of unrest at Mount St. Helens on September 23, 2004 initiated an uninterrupted lava-dome-building eruption that continued until 2008. The initial phase produced rapid growth of a lava dome as magma pushed upward. As shown in the video, an initial succession of lava spines, two recumbent and one steeply sloping, grew to nearly 500 m in length before disintegrating into mounds of rubble. The trajectory of lava extrusion was affected by the geometry of the crater, particularly the proximity of the vent to the south crater wall, and by the growing volume of erupted material.
http://gallery.usgs.gov/videos/643 "Lake Mead -- Clear and Vital" is a thirteen minute documentary relating the crucial role of science in maintaining high water quality in Lake Mead. The program was produced coincident with release of the Lakes Mead and Mohave Circular a USGS publication covering past and on-going research in the lakes and tributaries of the Lake Mead National Recreation Area.
In March 2008, a new volcanic vent opened within Halema‘uma‘u, a crater at the summit of Kīlauea Volcano in Hawaiʻi Volcanoes National Park on the Island of Hawaiʻi. This new vent is one of two ongoing eruptions on the volcano. The other is on Kīlauea’s East Rift Zone, where vents have been erupting nearly nonstop since 1983. The duration of these simultaneous summit and rift zone eruptions on Kīlauea is unmatched in at least 200 years. Since 2008, Kīlauea’s summit eruption has consisted of continuous degassing, occasional explosive events, and an active, circulating lava lake. Because of ongoing volcanic hazards associated with the summit vent, including the emission of high levels of sulfur dioxide gas and fragments of hot lava and rock explosively hurled onto the crater rim, the area around Halemaʻumaʻu remains closed to the public as of 2017. Through historical photos of past Halemaʻumaʻu eruptions and stunning 4K imagery of the current eruption, this 24-minute program tells the story of Kīlauea Volcano’s summit lava lake—now one of the two largest lava lakes in the world. It begins with a Hawaiian chant that expresses traditional observations of a bubbling lava lake and reflects the connections between science and culture that continue on Kīlauea today. The video briefly recounts the eruptive history of Halemaʻumaʻu and describes the formation and continued growth of the current summit vent and lava lake. It features USGS Hawaiian Volcano Observatory scientists sharing their insights on the summit eruption—how they monitor the lava lake, how and why the lake level rises and falls, why explosive events occur, the connection between Kīlauea’s ongoing summit and East Rift Zone eruptions, and the impacts of the summit eruption on the Island of Hawaiʻi and beyond.

Loss of their colleague David A. Johnston and 56 others in the eruption cast a pall over one of the most dramatic geologic moments in American history.
http://gallery.usgs.gov/videos/748 Magnitude 9.2: The 1964 Great Alaska Earthquake is a short video relating how the largest quake in U.S. history had profound and lasting impacts on our lives. The video features USGS geologist George Plafker who, in the 1960's, correctly interpreted the quake as a subduction zone event. This was a great leap forward in resolving key mechanisms of the developing theory of plate tectonics. Loss of life and destruction from the quake and accompanying tsunamis was the impetus for things like the NOAA Tsunami Warning Centers and the USGS Earthquake Hazards Program.
http://gallery.usgs.gov/videos/755 "1964 Quake: The Great Alaska Earthquake" is an eleven minute video highlighting the impacts and effects of America's largest recorded earthquake. It is an expanded version of the four minute video "Magnitude 9.2". Both were created as part of USGS activities acknowledging the fifty year anniversary of the quake on March 27, 2014. The video features USGS geologist George Plafker, who, in the 1960's, correctly interpreted the quake as a subduction zone event. This was a great leap forward in resolving key mechanisms of the developing theory of plate tectonics. Landslide impacts and the extreme tsunami threat posed by these quakes are also discussed. Loss of life and destruction from the earthquake and accompanying tsunamis was the impetus for things like the NOAA Tsunami Warning Centers and the USGS Earthquake Hazards Program.

Visit the USGS Multimedia Gallery (http://gallery.usgs.gov/videos/131) for this video and others. This four minute short movie depicts the hatching of a Mojave Desert Tortoise. This is the continuation of a sixty million year process for this threatened species. One of the surprising moments in the movie is when the hatchling tumbles from its shell and is propped up by its yolk. This is an evolutionary adaptation where the young absorb the yolk over several hours and they then use that nutrition to sustain themselves during the first few months of their lives. This is an especially handy adaptation as the young tortoises hatch in late summer when temperatures can exceed 110 degrees making the search for food especially difficult. The images shown here are part of a larger movie expected to be released by the USGS in November, 2009. That program will depict the USGS research program on the Desert Tortoise and the role of that research in managing desert environments to allow the species to recover and escape the threat of extinction. This movie was produced by the USGS Western Ecological Research Center and USGS Western Region Office of Communications in cooperation with the Las Vegas based Desert Tortoise Conservation Center, the U.S. Fish and Wildlife Service, the Bureau of Land Management, the Nevada Department of Wildlife and the San Diego Zoo.
http://gallery.usgs.gov/videos/562 Sound starts at: 0:53 Big Ol' Gal This female Burmese python broke the records for her length -- 17 feet, 7 inches -- and the number of eggs she contained: 87. She was first captured in Everglades National Park by USGS researchers in the spring of 2012, when they followed a "Judas snake" -- a male python with a transmitter -- and found her nearby in the bushes. USGS scientists then outfitted her with two radio transmitters, a GPS device, and a motion-sensing device before releasing her back into the wild. The second radio transmitter was a failsafe, ensuring she wouldn't "go wild" again. The snake remained in the wild for 38 days and then was removed and euthanized. The information from this snake's every move -- each pitch, roll, and yawl -- was recorded by the motion detector, allowing biologists to piece together her behaviors, including her kills. Biologists plan to use detailed information about the snake's biology and activity patterns to develop control methods for this invasive species. Pythons are effective at blending in the tall marsh grasses that give the Everglades its nickname, "The River of Grass," making it hard to spot the pythons even when they are being radiotracked.
