This video shows the inlet along the western margin of the lava lake in Halema‘uma‘u Crater, at the summit of Kīlauea. The lava stream was moving slowly but steadily, and was emerging beneath a portion of crust attached to the lake margin. The video is shown at 10x speed.
 

The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor is located aboard NASA’s Terra and Aqua satellites. The Visible Infrared Imaging Radiometer Suite (VIIRS) sensor is aboard the Suomi National Polar-orbiting Partnership (S-NPP) satellite. Together these sensors provide us with over two decades of crucial data for studying changes that have occurred on the

The Bay of Fundy in Canada has a unique geography funneling the Atlantic Ocean into some of the world's highest tides. At some points the water level can rise and fall over forty feet. The water's edge at Minas Basin shown in these Landsat 8 images changes dramatically depending on the day and time. Because Landsat 8 passes over quickly, the imagery cannot reveal the

The good news is that volcanoes usually change behavior before they erupt, in ways that are detectable by monitoring instruments. During times of relative quiet, scientists use different sensors and instruments to help visualize and quantify the structures and processes that are occurring beneath a volcano so they can provide a better estimate of what might happen when a

The U.S. Geological Survey is the science research agency for the U.S. Department of the Interior. We conduct research on the natural hazards that threaten lives and livelihoods around the country. We also monitor the water, energy, minerals and other natural resources we rely on; the health of our ecosystems and environment; and the impacts of climate and land-use change

This is an animation showing the changing conditions of USGS streamgages from January 1, 2021 to March 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.

In January, the Pacific Northwest (particularly, western Oregon

There are thousands of volcanic features distributed throughout the southwest United States, which are grouped together in volcanic fields. The Yellowstone Volcano Observatory monitors these volcanoes using a combination of techniques. While YVO hasn’t seen anything to suggest magma is on the move, the area is stretched and pulled apart to produce numerous tectonic

This video provides background on and shows the release of California red-legged frog tadpoles into a pond in San Diego County, CA on March 31, 2021. These tadpoles originated from a pond in the Sierra San Pedro Martir Mountains in Baja California, Mexico and were translocated as eggs to the USA on Feb 4, 2021 as part of a multi-national conservation team consisting of TNC

With existing USGS tools you can search for scenes, view thumbnail browse images of scenes, and download scene-based data, all derived from the USGS archive of scene-based products. Now that Landsat scene data has been unpacked and stored in the cloud, LandsatLook 2.0 can access that data and present it to users in ways that were not previously possible. Thanks to the

A mudslide near the 2020 Dolan Fire's ignition point chopped through a chunk of California's scenic State Highway 1 in late January. 

The Dolan Fire began near Big Sur on August 18th, 2020. It scarred nearly 125,000 acres before being fully contained in December. 

The damage is clear in false color Landsat 8 imagery from August and October. The scar is still

The lava lake remains active in Halema‘uma‘u Crater, at the summit of Kīlauea. This video shows the inlet where lava from the western fissure is supplied to the lake. The motion of the lava stream is sluggish, and this video is shown at 20x speed.

Throughout most of human existence, we haven't known much about how volcanoes work. Because of their immense power, they have terrified and fascinated us, and remain places of great spiritual importance for many people. The lack of knowledge about volcanoes has sometimes resulted in tragic and deadly disasters. But with the emergence of the science of volcanology and as

The Earth As Art project began in the early 2000s, and its original intent remains the same: to produce images that do not look like satellite images at first glance. Earth As Art shows not only what satellites capture in the visible wavelengths of light you and I can see, but also what’s hiding in the invisible wavelengths that Landsat sensors can detect in the infrared

The Volcano Disaster Assistance Program (VDAP) is a team of USGS scientists funded by USAID and the USGS Volcano Hazards Program to help volcano observatories around the world. Catalyzed by the 1985 Nevado del Ruiz catastrophe, the USGS and USAID developed VDAP as a dedicated team of volcano scientists with a cache of instrumentation ready to respond to volcanic crises (at
