Photograph showing a high scarp cut into the large pile of stamp sandsPhotograph showing a high scarp cut into the large pile of stamp sands at the town of Gay, Michigan. Nearly a century of erosion by waves and currents has transported millions of cubic yards of mine tailings along the coast and spread them across the adjacent lake floor.

Intern Learning Streamflow Measurement
Streamflow training at Blackrock Creek below Split Rock Creek near Moran, Wyoming. A new student intern learns how to measure streamflows upon arriving in Riverton just in time for high water.

Fire Danger Expected Number of Fires per PSA
This map takes into account both probability of ignition and conditional probability of spread (to 500+ acres in East and 1000+ acres in West*) given ignition.

Fire Potential Index (FPI) forecast
The FPI is most similar to the Energy Release Component of the National Fire Danger Rating System in that both are moisture related indexes and neither indicates the effect of wind on fire potential.

How do lava flows cool and how long does it take?
This ‘a‘ā flow erupted from fissure 8 on Kīlauea Volcano's lower East Rift Zone on June 1, 2018, shows how the interior of a lava flow remains incandescently hot even though surface cooling forms a crust of solid rubble.

Kīlauea Volcano's summit
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).

Image of the Week - Burning Man
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.

Low sulfur emissions mean a new focus on a different volcanic gas
Low sulfur emissions mean a new focus on a different volcanic gasA USGS pilot and Hawaiian Volcano Observatory gas geochemist prepare to conduct a test flight of an unmanned aerial system (UAS) on Kīlauea Volcano in November 2018. This UAS was outfitted with a prototype miniaturized multi-gas sensor for the detection of volcanic gases emitted by Kīlauea, including sulfur dioxide and carbon dioxide.
