Rocks from the east rim of Kīlauea Volcano's summit vent fell into the lava lake at 10:02 p.m., HST, on Saturday, August 6, triggering an explosive event that hurled fragments of molten and solid rock onto the rim of Halema‘uma‘u Crater.

Main hydrothermal features of the new (2016) 3-D model of the subsurface at Long Valley Caldera. This schematic is based on a survey of the electrical properties of the earth (magnetotellurics) below. Arrows show subsurface water flow, with colors keyed to changing water temperature, from blue (cold) to red (hot). Purple arrows show an extinct hot water pathway.

USGS scientists Christopher L. Shope, Bryan Downing, Katy O'Donnell and Mike Freeman measure nutrient levels in Goggin Drain, Utah. USGS scientists are conducting an experimental study on two Utah water bodies to gain a better understanding of nutrient levels, which could help determine how to best manage algal bloom outbreaks.
