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.

This short video provides a quick look at the Application for Extracting and Exploring Analysis Ready Samples (AppEEARS). AppEEARS provides a simple and efficient way to subset, transform, and visualize geospatial data distributed from a variety of federal archives.

Changes at the summit of Kīlauea between April 14 and August 20, 2018, were captured by a USGS–Hawaiian Volcano Observatory camera. This time-lapse series includes roughly one image per day. The lava lake within Halema‘uma‘u is visible in April, with overflows onto the caldera floor on April 23.

The camera glances at the bottom of the boat above and then pans down to the lake bottom. The lake bottom is covered in tons of round gobies swimming around in and out of the cladophora. Again the camera pans up to show a diver and the dive camera completing a transect in the distance.

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.

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.
