June 27th lava flow continues advancing NE

This image shows a broad overview of activity at the front of the June 27th lava flow. Steaming in the lower-center portion of the photograph issues from a crack on the East Rift Zone. A portion of the lava flow has entered this crack, and the steaming extends out 1.4 km (0.9 miles) from the visible flow margin at the surface. Presumably, this steaming results from groundwater heated by lava deep within the crack. In the upper-right part of the image, a smoke plume originates from a more northerly lobe that is advancing through thick forest, triggering small brush fires. The vent for the June 27th lava flow is on Pu‘u ‘Ō‘ō, the cone in the upper left part of the photo.
