This video shows the proper technique for collecting a skin swab from a bat that is either roosting in place or is manually restrained for white-nose syndrome surveillance.

Environmental samples collected in or near bat roosting locations can be used to supplement samples collected from bats for surveillance for white-nose syndrome (WNS) (https://www.usgs.gov/centers/nwhc/science/white-nose-syndrome).

Long-wave ultraviolet (UV) light can be used to detect orange fluorescence associated with white-nose syndrome (https://www.usgs.gov/centers/nwhc/science/white-nose-syndrome-surveillance) on bat skin.

In the spring, winter sea ice thaws and moves offshore leaving the coast exposed to increased wave action and relatively warm water temperatures that, when in contact with the bluff, erodes the toe of the bluff.

In September of 2019, a 315 ton iceberg known as D28 broke free from the Amery Ice Shelf in Antarctica. The berg has a surface area of more than 600 square miles, roughly comparable to the size of the Hawaiian island of Oahu. It's the largest iceberg to calve from the ice shelf since the 1960s.

The Unoccupied Aircraft System (UAS) that collected water from the crater lake in Halema‘uma‘u on October 26 was outfitted with both visual and infrared (thermal) cameras. This reconnaissance video shows fumarolic activity on the walls of the crater. Fumaroles appear light in color (yellow and white) in the visual imagery due to alteration of the crater wall rock.

In this October 26 reconnaissance survey, the Unoccupied Aircraft System (UAS) reaches the northeast part of the Halema‘uma‘u crater lake, where large rocks at the lake margin are often used to visually track the rising water level. Taken over a period of about 5.5 minutes, the survey is shown at 3 times the speed it was filmed.

Prior to the Unoccupied Aircraft System (UAS) mission that collected a water sample from Halema‘uma‘u at Kīlauea's summit on October 26, reconnaissance UAS missions were flown. This video, taken over a period of 15 minutes, has been sped up 7 times to show the UAS as it approaches Halema‘uma‘u from the southwest.

This thermal video was captured by the UAS as it collected a water sample in Halema‘uma‘u, at Kīlauea's summit.

This video was captured by the unmanned aircraft system (UAS) as it collected a water sample in Halema‘uma‘u, at Kīlauea's summit. Limited UAS flights in this area are conducted with permission and coordination with Hawai‘i Volcanoes National Park.

The dynamic landscape and climate of Alaska presents many challenges to the over 200 communities that live in rural areas of the state and have a wide variety of resource needs. Coastal and riverine erosion, flooding, wildfire, permafrost dynamics and increasing temperatures act as drivers for many of these landscape changes.

This timelapse video covers 1.5 hours and shows the motion of the water surface at the summit of Kīlauea. Along the shoreline, areas of apparent water influx are visible, often with a slightly greener color. Shifting steam on the surface attests to the high temperature of the water and the winds at the bottom of the crater.

Retrospective interview with USGS Geophysicist Susan Hough about the collapse of the Nimitz Freeway (known as the Cypress Structure) in Oakland, CA, during the October 17, 1989 Loma Prieta Earthquake and how the first responders reacted to the event.
 

Retrospective interview with USGS Geophysicist Susan Hough about her early earthquake work during the 1989 Loma Prieta earthquake. The interview covers how the Cypress Structure collapse in Oakland, CA, served as a site response study for seismic research.
 

Each year the State of California promotes a ShakeOut event where local citizens practice earthquake response and preparedness. This video shows footage from the 2019 Great California ShakeOut, which was hosted at Biola University in La Mirenda, CA. Video includes footage of the initial ShakeAlert announcement that blared across campus.
