This Quicktime movie shows the southern front of the June 27th lava flow
from Pu‘u ‘Ō‘ō. Lava
here has flowed into a deep crack on Kīlauea's East Rift Zone. The line of steam extending out from the visible flow margin at the surface is inferred to be caused by lava
deep within the crack. This video also shows the lava stream beneath the flow surface, supplied by a lava tube
, plunging into the crack.
