Several vents have opened on PuÊ»u ʻŌʻō’s northeast flank since last December. A spatter cone grew over one of the vents in mid-May and is visible at the center of the photo emitting bluish fume. In recent weeks, a vent opened upslope from (to the left of) the spatter cone, revealing bright incandescence. The northeast edge of PuÊ»u ʻŌʻō’s crater, filled with white fume, is to the left of this vent. Photo taken Thursday, June 16, 2016 courtesy of USGS/HVO
