On September 25, 2018, a team of three scientists based at the USGS–Cascades Volcano Observatory conducted the first-ever USGS-led Unmanned Aircraft Systems (UAS) campaign at Mount St. Helens. The UAS survey was conducted with the permission and coordination of the U.S. Forest Service Mount St. Helens National Volcanic Monument.

The team used a multi-rotor UAS (“

An important conservation strategy for climate change is to enhance and maintain regional habitat connectivity for the long-term viability of wildlife populations. Modeling habitat connectivity for wildlife species often results in a mapped network of linkages between habitat patches. A critical next step is to determine which of those linkages are priorities for

High-water marks provide valuable data for understanding recent and historical flood events. The proper collection and recording of high-water mark data from perishable and preserved evidence informs flood assessments, research, and water resource management. This video provides guidance for skilled high-water mark identification, including marks left behind in natural and

For this native South Dakotan, a love for math and a college trip to EROS in Sioux Falls, SD led to overseeing USGS's Landsat operations including the upcoming 2020 launch of Landsat 9. Read Jennifer's story and other #womeninscience stories at https://bit.ly/2D1RHk5

Ponderosa pine forests in the Black Hills of South Dakota are the focus of this week’s USGS Image of the Week.

Mountain pine beetles are about the size of a grain of rice, so of course we can’t see them from space in satellite images. What is visible is what the beetles can do to a pine forest. The washed-out pink color indicates large areas of standing dead or

The Unmanned Aircraft Systems (UAS) team completed its mission at Kīlauea Volcano's summit, mapping changes within the caldera. Since August 4, 2018, the number of earthquakes at the summit have decreased and the rate of subsidence has stabilized. Sulfur dioxide (SO₂) emission rates at the summit is less than 200 tonnes/day, which is lower than at any time since

Many lakes in South Dakota’s Prairie Pothole Region are expanding. 

Lake Thompson in eastern South Dakota is one that has displayed remarkable change in recent decades.

Each week, the Earth Resources Observation and Science (EROS) Center highlights a new satellite image(s) featuring striking changes in the Earth's surface. Our images come from locations

A closer view of the small cone forming on the floor of crater within fissure 8 today (Sept. 5). By this morning, bits of molten lava emitted from the cone every few seconds had built it up to an estimated height of around 3-4 m (about 10-13 ft).

An Unmanned Aircraft Systems overflight yesterday (September 4, 2018) showed a small cone on the floor of the crater within fissure 8. The cone formed as lava erupted from an opening on the surface of the flow that covers the crater floor.

On September 4-7, the Unmanned Aircraft Systems team flew several missions documenting changes within fissure 8 on Kīlauea's lower East Rift Zone. On September 4, lava erupted on the crater floor within the vent, building a small cone on the floor and creating a flow that did not extend beyond the vent walls. On September 5, gas bursts briefly lifted the crust over a small

During an overflight of fissure 8 this morning, HVO geologists observed low-level spattering on the new pad of lava within the cone. Slow-moving lava had just barely entered the spillway, but was not advancing down the channel.

During Kīlauea Volcano's lower East Rift Zone (LERZ) eruption, lava-flow maps were generated on a near-daily basis and published on the Hawaiian Volcano Observatory webpage. For the first week of the 2018 LERZ eruption, lava flows proved difficult to map, as they stayed close to the fissures in Leilani Estates, where vegetation obscured aerial views of their margins. Later

The Unmanned Aircraft Systems (UAS) team circumnavigates the crater rim at the summit of Kīlauea Volcano, collecting data for digital elevation models that document summit changes. The volume change, from early May 2018 to present, is over 825 million cubic meters (1 billion cubic yards). The vertical collapse of the crater floor is more than 500 m (1600 ft). Limited UAS

Title: What on Earth is going on at Kilauea Volcano?

• First significant summit explosions in nearly a century
• Largest summit collapse volume since at least 1800
• Voluminous fissure eruptions feeding channelized lava flow
• Unparalleled new opportunities for understanding the volcanic system
