PUNA, Hawaii – A huge breakout on the north flank of the Puʻu ʻŌʻō vent on the East Rift Zone of Kilauea volcano is sending waves of molten lava cascading downslope. Video of the event was recorded on Thanksgiving by Mick Kalber, filming from a Paradise Helicopters overflight.

Kalber says the tube opening begins about 150 yards below the vent and over the past two days has sent hot liquid rock more than a quarter mile down the north flank.

The breakout was noted in today’s USGS Hawaiian Volcano Observatory eruption update. “A breakout close to Puʻu ʻŌʻō was prominently visible on a nearby webcam beginning yesterday afternoon and continuing through the night,” scientists wrote. “The lava flow is not currently threatening any communities.”
