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.

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.
A helicopter overflight video of the lower East Rift Zone on June 14, 2018, around 6:00 AM, shows lava fountaining at fissure 8 feeding channelized lava flows that flow into the ocean. Lava is still flowing out of fissure 8 unabated and the channel is full. At the start of the video, standing waves in the lava channel can be seen near the vent exit. The channel appears crust-free from vent to the bend around Kapoho Crater. A surface crust forms over the channel as it spreads out during its approach to the ocean. The overflight along the ocean entry is from north to south along the coastline. The ocean entry is active along the whole length - approximately 1 mile. Small litoral explosions are occurring and there are several plumes of laze. ---------- Find this video and thousands more at https://usgs.gov/gallery.

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.
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.

Audio Description version at: https://www.usgs.gov/media/videos/k-lauea-volcano-video-compilation-kapoho-bay-ocean-entry This short video compilation shows conditions at Kapoho Bay during a helicopter overflight on June 4, 2018, around 6:15 a.m. HST and again around 1:38 p.m. HST. By 6:15 a.m., lava from fissure 8 had entered the ocean for over seven hours. The flow front was about a half-mile wide, with lava building a delta a few hundred yards into the bay. The ocean entry sends a large laze plume into the air along the coastline. In the second video, taken about seven hours later (around 1:38 p.m.), lava had nearly filled the shallow bay. ---------- Find this video and thousands more at https://usgs.gov/gallery.

Presenter: Larry Mastin, USGS Hydrologist - Yellowstone is one of a few dozen volcanoes on earth capable of "supereruptions" that expel more than 1,000 cubic km of ash and debris. - The plumes from such eruptions can rise 30 to 50 km into the atmosphere, three to five times as high as most jets fly. - Yellowstone has produced three supereruptions in the past 2.1 million years. The most recent was 0.6 million years ago. - Eruptions this large can create their own continental- scale wind field, pushing ash more than 1,000 km against the prevailing, ambient wind field.
