During HVO's early morning helicopter overflight along the coastline, orange streams of lava were entering the ocean in the vicinity of Ahalanui. Strong trade winds were pushing the white laze plumes inland.

Researchers start drilling an ice core in the Greater Yellowstone Ecosystem.

In this July 14, 2018, video captured by the UAS (Unmanned Aircraft Systems) team, lava was erupting from within the 120-foot-high fissure 8 cinder cone built of chilled lava fragments. Lava emerging from the cone was traveling about 13-16 miles per hour, flowing freely over a small set of cascades (rapids) and into a perched channel that was as much as 50 feet above the

Since early May 2018, the floor of Halema‘uma‘u Crater has dropped 450 m (about 1480 ft). Extensive cracking and faulting around the crater, along with inward slumping of the crater rim, has more than doubled its diameter. Like a balloon slowly losing air, subsidence occurs because magma in Kīlauea's shallow summit reservoir is moving into the East Rift Zone more rapidly

Listen to the sounds of rockfalls at Kīlauea Volcano's summit in this short video taken from the northeast rim of the caldera. At 2:42 p.m. HST on July 12, 2018, a collapse/explosion event at Kīlauea's summit released energy equivalent to a magnitude-5.3 earthquake. Rockfalls that occurred in Halema‘uma‘u and along the steep summit caldera walls during the event can be

Black rats were unintentionally introduced to Hawai’i in the late 1800s, most likely as hitchhikers on trading vessels. Since their introduction, they have disrupted native ecosystems by destroying native plants, eating native arthropods, and depredating bird nests. Black rats have contributed to population declines and species extinctions of Hawaiian forest birds, and

A whirlwind spins skyward on the northwest side of the fissure 8 cinder cone in this video taken on July 10, 2018. A number of whirlwinds have formed in the area due to the extreme heat of the open lava channel heating the air above it. As the heated air quickly rises, a light wind can push the air column to begin a rotation, which spins faster as it is stretched and

This series of images from June 13 through July 7, 2018, show dramatic down-dropping of part of Kīlauea Volcano's summit caldera floor. For weeks,

Since August 4, 2018, Kīlauea Volcano's summit activity has diminished dramatically. But between mid-May and early August, 62 collapse events occurred, with each releasing energy equivalent to a magnitude-5+ earthquake and causing extensive ground shaking in the summit area. On July 5, 2018, USGS video cameras stationed at various summit locations happened to record one of

This video describes the survey requirements for indirect measurements with multiple components, like flow going through a culvert and over a road on top of the culvert at the same time. 
 

In this video, you will learn what and where to survey for a road overflow or broad-crested weir indirect measurement. 
 

On June 30, 2018, at 02:51 PM HST, a collapse/explosion event occurred at Kīlauea's summit. An ash-poor

The USGS is developing methods to improve data collection during floods to gain new insight into the rise and fall of flood waters. In the past, the only data left behind after a flood was how high the water got, or the peak of the flood. This video presents the methodology that hydrologists are using to set up a Continuous Slope-area Reach in remote areas that are

The USGS Unoccupied Aircraft Systems (UAS) team conducted a flight on Kīlauea Volcano's lower East Rift Zone to collect video in the upper lava channel of 

Waterfowl populations in the northern Gulf of Mexico (NGOM) rely extensively on plants that grow under the surface in shallow waters, know as submerged aquatic vegetation (SAV), as a critical food resource in the winter season. SAV roots, shoots, and seeds provide high carbohydrate wildlife food that sustains valuable waterfowl species, including the American Wigeon,
