Pu‘u ‘Ō‘ō on May 3, 2018, as viewed from the helicopter overflight. The crater floor is collapsed, and a thin plume escapes from the gaping crater. The west flank cracked on April 30th around 2:30 pm HST, and minor amounts of lava oozed out of the crack (line of steaming features) just before the plumbing system catastrophically failed.

A sensor data logger recovered from the floor of Yellowstone Lake in the Deep Hole area in 2018 shows signs of melting due to unexpectedly high temperatures in sediments up to ~3 ft (1 m) away from an active hydrothermal vent. Image acquired by the Global Foundation for Ocean Exploration ROV Yogi on August 4, 2018.

Color bands in this radar interferogram depict the pattern of surface deformation at the Yellowstone caldera from September 22, 2004, to August 23, 2006. The southwest and northeast parts of the caldera floor rose about 11 cm (4.3 inches) and 15 cm (5.9 inches), respectively, while the north caldera rim near Norris Geyser Basin subsided about 7 cm (2.8 inches).

At Kīlauea's summit today, a clear morning gave way to heavy rain, which re-mobilized the ash cover between HVO and the Southwest Rift Zone, concentrating the ash in washes.

USGS hydrologist Taylor Dudunake assesses the rip-rap countermeasure along the pier of the Iowa State Route 76 bridge over the Upper Iowa River near Dorchester, Iowa. The assessment was part of a nationwide study of bridge scour countermeasures the USGS conducted on behalf of the Federal Highway Administration.

Four diesel-powered compressors chained to the deck of the R/V Hugh R. Sharp provided the air to power the seismic sources during the MATRIX cruise.

Kīlauea Volcano’s summit, seen here from the northeast rim of the caldera, has remained quiet, with no collapse events since August 2. It remains too soon to tell if this diminished activity represents a temporary lull or the end of summit collapses.

A completed restoration field trial site just after installation. Half of the site is seeded, and the other half had plants and weed cloth (white fabric) installed.

These workers are planting seedlings as part of the restoration field trial network. Each garden in the network is examining seedlings and seeds in conjunction with restoration treatments to better und
