An Unmanned Aircraft Systems overflight yesterday (September 4, 2018) showed a small cone on the floor of the crater within fissure 8. The cone formed as lava erupted from an opening on the surface of the flow that covers the crater floor.

During an overflight of fissure 8 this morning, HVO geologists observed low-level spattering on the new pad of lava within the cone. Slow-moving lava had just barely entered the spillway, but was not advancing down the channel.

During Kīlauea Volcano's lower East Rift Zone (LERZ) eruption, lava-flow maps were generated on a near-daily basis and published on the Hawaiian Volcano Observatory webpage.

The Unmanned Aircraft Systems (UAS) team circumnavigates the crater rim at the summit of Kīlauea Volcano, collecting data for digital elevation models that document summit changes. The volume change, from early May 2018 to present, is over 825 million cubic meters (1 billion cubic yards). The vertical collapse of the crater floor is more than 500 m (1600 ft).

Every year, tens of thousands of people descend upon an unforgiving windswept playa in northwestern Nevada to build a city.

Within months, the city is gone.

Burning Man is named for the wooden effigy set ablaze at the end of the weeklong celebration in the temporary metropolis of Black Rock City.

Diver travelling along the surface of the lake along with the dive camera system. The crew on the boat are there to meet the divers along with pulling the center pivot back onto the boat with the help of the davit.
 

Smallmouth bass swimming near lake bottom. The camera pans up a couple times to show the center pivot where the diver is holding on.
 

A total solar eclipse darkened the skies over the United States on Aug. 21, 2017.

Fourteen states were in the path of totality, a 70-mile-wide band under which the moon fully blocked the sun for just under three minutes.

An Unmanned Aircraft Systems overflight of fissure 8 on August 21, 2018, showed no incandescence within the cinder cone. Minor amounts of gases, primarily steam, rose from the north wall of the cinder cone and from areas along the lower East Rift Zone.

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.
