- Lava lake activity at Pu'u 'O'o crater in July 2007, Part 5: lava lake overturns -


East vent spattering in Pu'u 'O'o crater, 14 July 2007

Spattering vent feeding the lava lake in the West Gap. Pahoehoe lava flows on the lava lake's surface.
Details of the fresh lava surging out of the interior as the lake overturns quickly.
The lava lake immediately before a new overturn and the starting cell of the next overturn. Sequence of domino-style overturning sections of the lake's crust. The sequence takes less than 10 seconds.
The propagating overturning crust has reached the rim of the crater. The fresh surface of the overturned lava lake glows red for a few seconds after the overturn. A large part of the lake's crust has overturned.
Almost the whole crust of the lava lake has quickly overturned. Fresh lava surface. Overturning, ring-shaped sections of crust.
