Time-lapse images of Mount St. Helens dome growth 2004-2008
 
01:27
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.

Mount St. Helens' Runaway Glacier:  A time-lapse video of Crater Glacier
 
02:13
http://gallery.usgs.gov/videos/593 From 2005 to 2010, the U.S. Geological Survey-Cascades Volcano Observatory operated a remote camera on the northwest flank of Mount St. Helens. Looking into the crater, the camera captured hourly photographs of volcanic dome growth during the 2004-2008 eruption. The station also captured the advance of the west arm of Crater Glacier as it moved northeast around the 1980-1986 and 2004-2008 lava domes, joined with the east arm of the glacier, and pushed northward onto the crater floor. The time-lapse sequence links individual photographs to produce a video of the movement of Crater Glacier, showing the glacier's remarkable run-away response to volcanic dome growth.

Hatching of a Mojave Desert Tortoise
 
04:51
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.

Shaking of Atwood Building, Mw 7.0 November 30, 2018, Anchorage Quake
 
02:13
This video presents a visualization of how the Atwood Building in Anchorage, Alaska, shook during the Mw 7.0 November 30, 2018, Anchorage, Alaska, earthquake. The building was instrumented by the U.S. Geological Survey to obtain data to study its behavior and performance during strong shaking. Such data are useful in making decisions about improving the performance of the building. Note that relative to the height of the building, the motions are magnified by a factor of 100 to show how the building deforms. Translational (back-and-forth) motion (more dominant in the East-designated direction) and limited torsional (twisting) motions are both observed, as well as limited beating effects (alternating cycles of generally increasing and decreasing levels of motion that occur when the structural damping of a building is low and when frequencies of translational and torsional motions are close). An earlier video of the Atwood building visualizing shaking during the Mw7.1 January 24, 2016, Iniskin, Alaska, earthquake can be found at: https://www.usgs.gov/media/videos/shaking-atwood-building-anchorage-alaska.

Image of the Week - A New Yellowstone Hot Spot
 
01:12
USGS A New Yellowstone Hot Spot More than 10,000 thermal features pepper the landscape of Yellowstone National Park. Most of the hot springs, geothermal vents, and geysers are clustered around 120 distinct thermal areas. Scientists with the USGS Yellowstone Volcano Observatory use satellite and aerial imagery to map them as they expand and contract. They recently found an entirely new thermal area. It emerged quietly over 20 years, miles from the nearest trailhead but close to an existing hot zone. Landsat 8's thermal infrared sensors captured the change in a nighttime image from April of 2017. Heat signatures are clearest at night, when unheated ground is cool. Aerial images told more of the story. Forest covered the area in 1994, but the emergent thermal zone had begun to fry trees by 2006. Before long, the hot spot was unmistakable, with felled trees piled like toothpicks in a patch of land roughly the shape of a thumbprint. Scientists rely on both satellite and high-resolution airborne imagery archived with the Earth Resources Observation and Science (EROS) Center to monitor Yellowstone. USGS

USGS Scenario Evaluator for Electrical Resistivity Survey Design Tool
 
04:23
This video provides an overvew of the USGS Scenario Evaluator for Electrical Resistivity (SEER). Today’s environmental site managers have many tools to choose from when conducting site characterization and remediation. Geophysical tools can provide noninvasive ways to see inside the earth, much like how medical imaging lets us see inside the human body. The USGS Scenario Evaluator for Electrical Resistivity (or "SEER") is a quick and simple tool practitioners can use to assess the likely outcome of using two-dimensional electrical resistivity imaging for site characterization and remediation monitoring. Electrical resistivity imaging is a widely used geophysical method for environmental site management studies. The method is sensitive to fluid conductivity, interconnected porosity, saturation, clay content, and metallic materials. Additional Credits: Development of the tool was supported by the Environmental Security Technology Certification Program, the U.S. Environmental Protection Agency, and the USGS: Terry, N.C., Day-Lewis, F.D., Robinson, J.L., Slater, L.D., Halford, Keith, Binley, Andrew, Lane, J.W., and Werkema, Dale, 2017, Scenario Evaluator for Electrical Resistivity Survey Pre-modeling Tool: Groundwater, http://dx.doi.org/10.1111/gwat.12522.

Kīlaueau Volcano — Lava Flow Aerial
 
02:09
In this July 14, 2018, video captured by the UAS (Unmanned Aircraft Systems) team, lava was erupting from within the 120-foot-high fissure 8 cinder cone built of chilled lava fragments. Lava emerging from the cone was traveling about 13-16 miles per hour, flowing freely over a small set of cascades (rapids) and into a perched channel that was as much as 50 feet above the ground surface. The fissure 8 lava flow channel extends about 8 miles to the active ocean entry. UAS are assisting in the USGS eruption response. Hovering at about 1000 feet above hazardous areas, UAS collect video and images to map lava flow boundaries, track overflows, and help assess channel velocities. UAS can also carry sensors to collect thermal and gas data.

Kīlauea Volcano — Ever-Growing Halema`uma`u Crater
 
04:01
A UAS (Unoccupied Aircraft Systems) mission on June 24, 2018, filmed details of the dramatic changes occurring within Halema‘uma‘u crater at Kīlauea's summit since explosive eruptions of ash and gas and ongoing wall collapse began in mid-May. Clearly visible are the steep crater walls that continue to slump inward and downward with ongoing subsidence at Kīlauea's summit. The deepest part of Halema‘uma‘u is now over 400 m (1300 ft) below the caldera floor. There are two obvious flat surfaces within the crater that have slumped downward as nearly intact blocks - the shallower one is the former caldera floor and the deeper one is the former Halema‘uma‘u crater floor. Limited UAS flights into this hazardous area are conducted with permission and coordination with Hawai‘i Volcanoes National Park. The overflights collect visual information on what is happening at this rapidly changing eruption site. Scientists examine the footage in detail to understand how the expanding collapse area is evolving, the extent of tephra fall, and other surface changes. This information is used to assess hazards at Kīlauea's summit , which are shared with the National Park Service and emergency managers.

Forecast Mekong: Visualizing Shared Waters
 
05:25
Forecast Mekong: Visualizing Shared Waters Audio Script -- July 2011 The Mekong is one of the world's great rivers cascading through six Asian countries from the Tibetan Plateau to the South China Sea, connecting China, Myanmar, Laos, Thailand, Cambodia and Vietnam. How one country uses or changes the waters of the Mekong upstream can have important implications for the health of the river and people downstream. Increasing demands for hydropower and irrigation have prompted several countries to plan the construction of large dams on the Mekong River and its tributaries. The cumulative effects of such dams can be quantified through the use of hydrologic data and computer models. Visualization tools can help people develop a shared understanding of river resources and provide a science basis for critical decisions about regional development and sustainability. In 1995, the nations of the Lower Mekong basin established the Mekong River Commission to assist in the integrated management of the river flow and its ecosystem benefits. The Mekong River Commission, or MRC, has developed a suite of hydrology models within a decision-support framework to forecast changes in river flow and water quality from proposed development projects such as dams. The U.S. Department of State in cooperation with the U.S. Geological Survey and university partners are developing visualization tools to help policy makers and planners communicate and evaluate complex river issues. The flood waters of the Mekong River are critical to the food security and livelihoods of millions of people in Southeast Asia. From July to December, the Mekong swells with the addition of snow melt and monsoon rains, peaking in September and October, before receding to annual lows during the normal dry season. When turbid flood waters of the Mekong join the Tonle Sap River in Cambodia, there is a reversal of flow which more than quadruples the size of the unique Tonle Sap Lake. The natural expansion and contraction of the Tonle Sap Lake each year accounts for one of the world's most abundant inland fisheries -- a resource that is critical to food security in the region. Upstream dams pose potential environmental threats to the Tonle Sap and the lower Mekong River and Delta. While dams and reservoirs provide valuable services to society, they can also alter normal or natural flow regimes and fish migration. And while the impact of a single dam may be minimal, the cumulative effect of tens or hundreds of small tributary dams within a larger river system can be substantial depending on dam location, operation, and size. Over the next 20-30 years, the major area of water resource development is anticipated to be hydropower, the fundamental feature of which is the shift of water from the wet to the dry season via reservoir storage. Increased dry season flow decreases the risk of water shortages and increases the options for dry season irrigation to produce a second or third rice crop. Reservoirs and dams, depending on design, slow river runoff and capture sediment important for river life and delta nourishment downstream. New engineering methods, such as sluice gates, are being incorporated into dam designs to enhance the flush of sediments from reservoirs and minimize some of the downstream effects of dams. The flow regulation that results from dam construction may benefit some Mekong River residents, but changing natural water flow patterns can be problematic for sustaining the rich biodiversity of fish in the Mekong, particularly some species with long-distance migratory patterns. Migration patterns of important species can be graphically captured in the visualization to aid impact assessments of proposed dams with increased understanding of fisheries ecology of the Mekong. Forecast Mekong is building partnerships with the Mekong River Commission and others to develop advanced computer applications and visualizations that will enhance the understanding of complex river issues and the results of hydrologic models used to coordinate the development of water resources in the Mekong Basin from the mountains to the sea. The six nations that share the Mekong River will all benefit from a commonly-held understanding of the benefits, trade-offs, and impacts of water resource development. Scientific visualization provides a powerful tool for improving future planning and harmonizing the development of the Mekong for people, fish, and wildlife.

The HayWired earthquake scenario, led by the U.S. Geological Survey (USGS), anticipates the impacts of a hypothetical magnitude-7.0 earthquake on the Hayward Fault. The fault is along the east side of California’s San Francisco Bay and is among the most active and dangerous in the United States, because it runs through a densely urbanized and interconnected region. Get Ready! Analyses of impacts related to the HayWired earthquake scenario include estimates for potential fatalities, injuries, water outages, fires, and other major disruptions. These could potentially include: 800 deaths, 16,000 nonfatal injuries, property and direct business interruption losses of more than $82 billion from from shaking alone. The USGS and its partners are working to energize residents and businesses to engage in new and ongoing efforts to prepare the region for such a future earthquake.

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.

Understanding Land Surface Temperature Dynamics
 
04:05
From development and land cover differences to elevation, many factors influence land surface temperature (LST) dynamics. The Earth’s surface temperature can be measured using LST data from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the National Aeronautics and Space Administration’s (NASA) Aqua and Terra satellites and the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) sensor onboard the Terra satellite. LST measurements can be used to study climatic phenomena such as the urban heat island (UHI) effect and deadly heatwaves. This data visualization was created using MODIS and ASTER data distributed by NASA’s Land Processes Distributed Active Archive Center (LP DAAC), located at the USGS Earth Resources Observation and Science (EROS) Center. For more information: LP DAAC: https://lpdaac.usgs.gov/ MODIS LST: http://doi.org/10.5067/MODIS/MYD11A2.006; http://doi.org/10.5067/MODIS/MOD11C3.006 MODIS Leaf Area Index: http://doi.org/10.5067/MODIS/MYD15A2H.006 ASTER Surface Kinetic Temperature: http://doi.org/10.5067/ASTER/AST_08.003 ASTER Level 1 Precision Terrain Corrected Registered at-sensor Radiance: http://doi.org/10.5067/ASTER/AST_L1T.003

Kīlauea Volcano — Video Compilation of Kapoho Bay Ocean Entry
 
01:01
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.

Shaking of Frontier Building, M7.0 November 30, 2018, Anchorage Quake
 
02:24
This video presents a visualization of how the Frontier Building in Anchorage, Alaska, shook during the moment magnitude (Mw) 7.0 November 30, 2018, Anchorage, Alaska, earthquake. The building was instrumented by U.S. Geological Survey to obtain data to study its behavior and performance during strong shaking. Such data are useful in making decisions about improving the performance of this and similar buildings. Note that relative to the height of the building, the motions are magnified by a factor of 150 to show how the building deforms. Translational (back-and-forth) motion (dominant in the east-designated direction) and limited torsional (twisting) motions are observed. An earlier video of the Frontier Building visualizing shaking during the Mw 7.1 January 24, 2016, Iniskin, Alaska, earthquake can be found at https://www.youtube.com/watch?v=A6EG7NXel9g. ---------- Find this video and thousands more at https://usgs.gov/gallery.

Time-lapse video of bluff erosion on Barter Island, Alaska
 
01:20
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 shoreline to study wave and shoreline dynamics. This video starts on June 1st at -4°C (25° F) when the bluffs are still frozen, snow is on the ground, and the winter pack ice protects the permafrost cliffs from wave attack. By the end of June, the ice and snow are gone, temperatures often climb to 12°C (54° F), and waves begin to lap at the narrow beach below the bluffs. In mid-July, the now-thawed, upper active layer of the tundra begins to slough off onto the beach. By the end of July, waves accompanied with elevated storm-tides erode the lower part of the slope. Just days later, as erosion increases rapidly, the bluff supporting the camera gives way and the camera tumbles onto the beach. Despite its fall onto the muddy beach, the camera continued to record and was successfully recovered in order to create this video. The USGS is studying this highly erosive stretch of Arctic coastline to try to better understand the main driving forces behind the erosion and why erosion rates seem to be increasing. The increase is likely the result of several changing arctic conditions, including declining sea-ice extent, increasing summertime sea-surface temperature, rising sea level, and possible increases in storm power and corresponding wave action. More long-term work is needed to understand the interplay of these factors and how they drive changes in coastal erosion.
