Landsat and Sentinel sensors capture the Rattlesnake Fire as it burns in Arizona.
At the USGS EROS Center, we study land change, operate the Landsat satellites, and maintain the longest, continuously acquired collection of images of the Earth's land surface.

On the morning of May 9, 2018, a large rockfall in "Overlook crater" within Halema‘uma‘u at the summit of Kīlauea triggered a gas-driven explosion that sent an ash plume several thousand feet skyward. Phreatic (steam-driven) explosions can create larger ash plumes; the 1924 explosions sent ash plumes up to 20,000 feet high. USGS photo.

To help us understand what could happen at Kīlauea Volcano's summit, we look to past similar events, but this does not mean that future events will be exactly the same. This map shows the distribution of ballistics and tephra from the 1924 phreatic (steam-driven) explosions.

Good weather provided clear views into Pu‘u ‘Ō‘ō crater. The crater floor collapsed on April 30 as magma drained to the east along the East Rift Zone. Based on a 3D model constructed from thermal images, the deepest part of the crater was 350 m (1150 ft) below the crater rim.

During an overflight on May 11, we collected thermal images of the crater at Pu‘u ‘Ō‘ō and created an updated 3D model of the crater geometry. The collapse on April 30 produced a large cavity, with the deepest point roughly 350 m (1150 feet) below the crater rim.

On May 10, 2018, Highway 130 (shown here) was newly cracked with steam coming up from the east side of the road due to the dike (tabular body of magma) that intruded Kīlauea's lower East Rift Zone. The two orange and white road markers are on slightly uplifted areas of the highway, which are about 100 m (330 ft) apart.

A team of USGS scientists work off the R/V Sallenger in Rockaway Beach, New York. One team member stands on a floating sled that enables sub‐bottom surveying in shallow water, nearshore, and shore‐face environments. The sled is equipped with an EdgeTech SB‐512i CHIRP system and single‐beam sonar.

USGS scientists measure beach elevation and other profile characteristics as part of a project that models how barrier islands will likely change with sea-level rise - and how those changes will ultimately affect piping plover and other shorebird nesting habitat availability.

Michael Toomey, Jessica Rodysill, and Tom Sheehan collect sediment cores from Lake Drummond, located within the Great Dismal Swamp. The cores were obtained using a vibracore, which was mounted on a platform between two canoes.

Established in 2009, the U.S. Geological Survey’s Coral Assessment Network (USGS-CAN) provides data on coral-growth (calcification) rates throughout the Florida Keys. Pictured here is one of 30 stations located in in Dry Tortugas National Park.
