A new lava flow begins as another ends
Detailed Description
Elevated pressure within Pu‘u ‘Ō‘ō cone reached a breaking point on June 27 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 a.m. This new activity was accompanied by minor sagging of the Pu‘u ‘Ō‘ō crater floor, due to withdrawal of magma within the cone.
