Puʻu ʻŌʻō started as a cinder and spatter cone in the 1980s, but over the past 30 years flank vents on the cone have produced stacks of lava flows, creating a broad shield around the cone. This view looks north and shows the shield shape clearly. Mauna Kea Volcano can be seen in the distance. Photo taken Thursday, March 16, 2017 courtesy of USGS/HVO
