Photos of an ash cloud rising from Pu‘u ‘Ō‘ō as crater floor collapses, the collapsing crater, and erupting fissures. Video clips of the fissure eruption between Pu‘u ‘Ō‘ō and Nāpau Crater.
Ash cloud rising from Pu‘u ‘Ō‘ō as crater floor collapses
Ash cloud rising from Pu‘u ‘Ō‘ō as crater floor collapses due to magma withdrawal. Incandescent rubble can be seen crumbling and rolling down the scarp. The east rim of Pu‘u ‘Ō‘ō is in the foreground.
Incandescent rubble rolling and sliding down the scarp on the edge of the collapsing crater in Pu‘u ‘Ō‘ō. A remnant of the pre-collapse crater floor can be seen in the background below the crater's south wall. The east rim of Pu‘u ‘Ō‘ō is in the foreground.
Video clips of the fissure eruption between Pu‘u ‘Ō‘ō and Nāpau Crater
Video clip shot from the air looking SW at the fissure eruption between Pu'u 'O 'o and Napau Crater. The fissure segment in the tephra in the foreground opened seconds earlier, and only about 10 minutes after the eruption as a whole started. The cracks through the tephra are in the process of opening, though this can't be picked out at this distance.
Video clip shot in front of the propagating fissure, showing low spattering that started moments earlier. Thick white steam from the crack in the foreground indicates that lava is about to reach the surface, and is seen doing so seconds later.
New fissure eruption SW of Pu‘u ‘Ō‘ō between Pu‘u ‘Ō‘ō and Nāpau crater. Spatter is reaching 15-20 m into the air, above the trees. Pu‘u ‘Ō‘ō in the background.
