A deflation-inflation (DI) event, which began yesterday afternoon, led to a marked decrease in eruptive activity at Pu‘u ‘Ō‘ō overnight. The western lava lake, at upper right, became inactive, while the eastern lava lake, filling the center of the frame, dropped several meters and became very sluggish. The drop in level revealed islands nearly hidden when the lake was full. The view is toward the south.
Two vertical air photos, stitched together, show all of Pu‘u ‘Ō‘ō's crater. The islands within the eastern lava lake, to the right, give it an appearance somewhat like Edvard Munch's "The Scream". This perspective also shows the western lava lake, just left of center, and the channels that carried lava from the western lava lake into two perched ponds satellitic to the main western lake. The perched pond at upper left is formed on top of what was, three days ago, a pit called the West Gap pit. The perched pond at lower left is formed on top of what was the Puka Nui pit, which was filled in late July.
