New breakout on the NE flank of Pu‘u ‘Ō‘ō

Detailed Description

Elevated pressure within Pu‘u ‘Ō‘ō cone reached a breaking point this morning with magma intruding through the cone and erupting from fissures on the northeast flank of the cone. These new vents fed a vigorous, but still relatively short, channelized flow that had reached about 1.5 km (0.9 miles) northeast of Pu‘u ‘Ō‘ō by 11 am. This new activity was accompanied by minor sagging of the Pu‘u ‘Ō‘ō crater floor, due to withdrawal of magma within the cone.
