At Mount Baker, Washington, observers noted continuing landslide activity in the upper Middle Fork Nooksack drainage that resulted in small debris flows and muddy floods. Scientists from multiple agencies and institutions coordinated observations, surveying, and sampling to gain an understanding of the situation.

On Kīlauea's East Rift Zone, the Kahauale'a 2 flow advances slowly into the Puna Forest Reserve. The Kahauale`a 2 flow began in early May, 2013, on the north side of the rift.

The Kahauale‘a 2 flow, which is active north of Pu‘u ‘Ō‘ō, is fed from a vent at this cone on the northeast rim of Pu‘u ‘Ō‘ō crater. Small openings at the top of the cone contain sloshing lava, and two skylights at the very start of the Kahauale‘a 2 lava tube provided views of a swiftly moving lava stream rushing downslope.

Localized flooding on Hidewood Creek near Estelline, SD, on June 23, 2013. Severe storms during June 21-22, 2013, in eastern South Dakota resulted in high flows in several streams across the area. The peak discharge on Hidewood Creek (streamgage 06479640) from this storm event was about 4,200 cubic feet per second.

This geologic map of Mauna Loa shows surface flows that have been mapped as of 2013. The flows are color-coded to reflect age. Warm colors indicate younger flows, with red indicating flows erupted since 1832. Cooler colors indicate older flows, such as at South Point, which is covered by flows ranging from 7,000 to more than 21,000 years old (blues and purple).
