Mar 7, 2014: View of Pu‘u ‘Ō‘ō from the south. Pu‘u ‘Ō‘ō's tan-colored south flank is composed of cinder and spatter erupted in its early years (mid-1980s). Since that time, the cone has partially collapsed and lava flows have erupted on the flanks and within the crater, sometimes spilling over the crater rim. In the crater, there have recently been several small spatter cones emitting fume. Mauna Kea's snow-covered summit is visible in the distance.
