  • USGS / HAWAIIAN VOLCANO OBSERVATORY                                  A closer look at the breakout point where lava emerged from the tube on November 25. A few skylights provide views of the lava in the new lava tube that formed over the past week on this flow.

  • USGS / HAWAIIAN VOLCANO OBSERVATORY                                  Scattered breakouts persist northeast of Puu OO, and the farthest reach of active breakouts was about 3.7 milesfrom the vent on Puu Oo on Dec. 3. A minor change on the flow field occurred, 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 Puu Oo.

  • USGS / HAWAIIAN VOLCANO OBSERVATORY                                  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.

Scientists at the Hawaiian Volcano Observatory posted new pictures on their website of a lava breakout that began last month.

The active flow started on Nov. 25th and is within four miles of Puu Oo vent . The flow is still too far away from any communities to pose a threat.

Scientists report that there is some minor burning in an area where a lava flow meets a forest.

The latest pictures were taken on Dec. 3 and released over the weekend.

Webcamera images also show a new incandescent fuming source on the east rim of the crater. It appears to be a small collapse into an older, inactive lava tube.

At Kilauea, the lava lake at Halemaumau Overlook crater remains active. Intermittent spattering caused the lava lake level to fluctuate Saturday. The lake appears to be rising during a period of inflation.

Among the pictures posted on the HVO website are a couple of dramatic images, taken by a webcamera during a storm in October, that shows lightning above the glow created by the lava lake at Halemaumau.
