A minor change on the flow field occurred last week, with a breakout from the tube on November 25 that created a small flow that remains active today. This November 25 breakout is easily visible as the lighter colored area extending to the bottom of the photo. The breakout point is visible by the thick fume on the north flank of Puʻu ʻŌʻō.

A fascinating cross section of a hornito was revealed recently, when a partial collapse provided a window into a portion of an abandoned lava tube.

The void space behind the geologist was filled with lava at some point, with lava and gas forced through the narrow crack in the center of the photograph. This ejected bits of spatter, which solidified around the opening and built a tall hornito.
