All activity is now concentrated within four miles of the Pu`u `O`o vent. Mahalo Paradise Helicopters and Mick Kalber for the footage!
Many lava breakouts were observed this afternoon near Pu`u `O`o and up to about four miles below the vent. Quite obviously, the activity upslope has taken the lava supply from the Pahoa area, since below that point ZERO lava activity was noted anywhere. We believe the Pahoa flow can now be considered to have ceased. The bottom eight miles are completely inactive: no flowing lava, no burning trees, no smoke or steam. Activity anywhere near the geothermal pad has also stopped.
A great deal of surface lava was observed within four miles of the Pu`u `O`o vent. The north flank flow of the vent is apparently still active, but we saw no surface lava there, only smoke. Lava continued to flow in pahoehoe toes and more sizable outbreaks at numerous places downslope from the vent, and is once again burning the forest about a mile and a half below the vent. Air this morning was somewhat voggy, but had largely cleared up later in the day as winds are now blowing Pu`u `O`o’s plume to the south.
