The North spatter cone in Puʻu ʻŌʻō crater fed a new flow, starting Tuesday evening, that covered much of the northern part of the crater floor and spilled over the crater rim towards the north. The right side of the north spatter cone has been present for many months, but the left side, which was spattering Monday morning (April 28), is new as of this week. Photo courtesy of USGS/HVO
