Hawaii Pu'u O'o Volcano - Lava Up-date
September 22 update - A fissure breakout that started yesterday morning continued this morning. As of yesterday's overflight at about 3 pm, the flow had advanced as a channelized ʻaʻa flow about 2.5 km (1.5 mi) from Puʻu ʻŌʻō to the southeast within the Kahauale`a Natural Area Reserve. At about 4 am this morning, a second flow branch started to the west of the first. If the flows continue to advance, they will likely continue southeast, along the western edge of the Episode 58 (TEB) lava flow, toward Royal Gardens. In addition, a small pad of lava was actively refilling the bottom of the drained eastern lava lake and small seeps were barely active at the west edge of Puʻu ʻŌʻō Crater.
