This video, taken on February 10, 2022, shows lava upwelling at the western vent, in Halema‘uma‘u crater at the summit of Kīlauea, before flowing into the lava lake to the east via a narrow channel.

Narrated presentation that provides a unique, long-term perspective (1950-2050) of the major drivers of nitrogen change up to the present, and forecasts how they may affect nitrogen into the future for the Chesapeake Bay watershed. Information is based off of U.S. Geological Survey Circular 1486.

Landsat 7 had the honor of acquiring the satellite program’s 10 millionth scene in November 2021.

The scene captures changes to the Dead Sea, located in Southwest Asia. The Dead Sea is mainly fed by the Jordan River, which enters from the north. However, the water level of the Dead Sea has been falling due to irrigation projects and water use upstream.

The Arctic region is warming faster than anywhere else in the nation. Understanding the rates and causes of coastal change in Alaska is needed to identify and mitigate hazards that might affect people and animals that call Alaska home.

A Kīlauea summit eruption monitoring shift on February 4, 2022, provided views of the eruption within Halema‘ma‘u crater. Lava flows from a pond north of the west vent into the lava lake, which exhibits areas of spattering.

This monthly update from the Yellowstone Volcano Observatory begins with a story.

These video clips show recent activity at the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea. Lava upwelling at the western vent flows into the lake, where bubbling is commonly present. In the eastern portion of the crater, a steep spatter cone has produced vigorous spattering and small lava flows.

USGS geologist Dan Dzurisin is near Sisters, in Central Oregon, to set up portable GPS monitoring equipment to track something that's been going on for 25 years and still goes on today. It’s uplift, a subtle rise in the ground’s surface, in an area west of South Sister volcano.

On January 28, the USGS-Hawaiian Volcano Observatory conducted Unoccupied Aerial Systems (UAS) missions at the summit of Kīlauea, within Hawai‘i Volcanoes National Park.

HVO field crews participated in an overflight and ground work at the summit of Kīlauea on January 27. This video compilation contains footage taken from the air and ground.

In the winter of 2015, the public noticed thousands of dead seabirds washing ashore across the western coast of the United States and Canada. The USGS linked this massive seabird die-off to the North Pacific Marine Heatwave. A marine heatwave occurs when sea surface temperatures are above normal for an extended period of time.

2021 was an interesting year for deformation at both Kīlauea and Mauna Loa volcanoes. At Kīlauea, 2021 provided a glimpse of what the future might hold as the system recovers from the large collapses that accompanied the 2018 lower East Rift Zone eruption.

Mauna Loa is an active volcano, though it has been quiet for almost 30 years. An eruption is not imminent, but patterns of ground deformation on Mauna Loa over the past year may indicate that new, previously unobserved processes may have occurred. Mauna Loa lava flows have the capacity to disrupt lives and commerce throughout the Island of Hawai‘i.

It seems the effects of climate change were all too clear in 2021. Yet, we know more change is expected. When trying to adapt to a changing climate, with all the inherent uncertainties about how the future may play out, resource managers often turn to scenario planning as a tool.

The tallest volcano on the Galapagos Islands began erupting on January 6. The eruption sent lava flows down the mountainside and ash skyward. Like the Hawaiian Islands, the Galapagos are volcanic islands formed over an active hotspot. Wolf Volcano last erupted in May and June of 2015.

Communities on the Island of Hawai‘i continue to recover from Kīlauea’s 2018 lower East Rift Zone eruption and summit collapse as does the USGS Hawaiian Volcano Observatory (HVO). During the events of 2018, HVO instruments were lost, monitoring infrastructure was impacted, and HVO staff had to evacuate the observatory, which was damaged beyond repair.

Incredibly high sulfur dioxide (SO2) emission rates were measured during the lower East Rift Zone of Kīlauea in 2018—nearly 200,000 tonnes per day. Emissions dropped to only about 30 tonnes per day during Kīlauea’s non-eruptive quiet period from 2018–2020.

This video highlights the Geomorphology team at the MD-DE-DC Water Science Center, and features interviews with several USGS scientists.

They discuss what skills they possess, what technologies they use, and how their research helps advance the mission of the USGS.

Recent activity has altered the landscape in northwestern China. Alluvial Fan, from the second Earth As Art collection, was acquired in 2002 by the ASTER sensor on NASA’s Terra satellite. It’s truly a fan favorite, often named one of the top images of the entire collection.

This is an animation showing the changing conditions of USGS streamgages from October 1, 2021 to December 31, 2021. The river conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring around a gage indicates it is flooding.
