June 27 breakout building a lava shield near Pu‘u ‘Ō‘ō
Detailed Description
The June 27 breakout initially produced a channelized lava flow that reached Pu‘u Kahauale‘a (about 1.5 km, or 0.9 miles, from the vent) during the first day, but over the past two days the surface flows have retreated closer to the vent, building a lava shield (visible just above the center of the photograph).
