Aerial view showing dark pahoehoe
Detailed Description
Aerial view showing dark pahoehoe and `a`a flows that spilled out of Puka Nui (collapsed area at southwest base of Pu`u `O`o in right background) on April 5-6. Several elongate collapse depressions show location of past lava tubes, now inactive. Orange discoloration indicates areas of chemical alteration caused by now-dead fumaroles.
