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.

50,000 tons of sulfur dioxide gas per day
In mid-July 2018, fissure 8 (shown here) on Kīlauea Volcano's lower East Rift Zone was emitting more than 50,000 tons of sulfur dioxide gas per day, creating high levels of vog on the island. Since early August, lower East Rift Zone SO2 emissions have dropped to less than 100 tons per day, resulting in better air quality for Hawaii.

Impact of Hurricane Lane on Wailuku River
Two views from the Rainbow Falls overlook, downstream of the Wailuku River streamgage near Hilo, Hawaii. The image on the left shows a typical base flow of about 35 cubic feet per second (cfs). The image on the right shows the early impact of Hurricane Lane with a flow of about 26,000 cfs taken at 8:35 a.m. HST, August 23, 2018. This U.S.
