Reading today's update (11/10), I'm not seeing that the lava is turning south. What I'm reading is that they know a northern tube is active but the magma hasn't broken out yet. And even if the "east tube" is spilling over to the south, the most active tube is still to the east. But I'm no geologist, please correct my reading ...
"Activity Summary for last 24 hours: The perched channel continued to feed seeps and tubes. The most active area was where the east tube fed several pahoehoe flows advancing slowly eastward in the vicinity of Pu`u Kia`i.
Activity Summary for the past few months: Lava erupted from the 7/21 fissures is probably fed from a shallow magma storage area beneath Pu`u `O`o where it degasses before being erupted. In September and October, the channel system continued to produce lava flows that were shorter than those erupted during August causing the area covered by 7/21 flows to get wider in the northwest-southeast direction but not longer in the northeast direction. In late October, tube-fed pahoehoe flows developed and advanced along the north and south margins of the flow field.
In the last few weeks, the east tube has produced pahoehoe flows along the south margin that advanced nearly as far to the east as the August flows before stalling. The east tube remains the most active one.
Last 24 hours at 7/21 eruption site: ... (edited to highlight relevant portion)
Lava was entering the east tube inlet which was feeding several east-moving pahoehoe flows in the vicinity of Pu`u Kia`i (see map).
One north-going tube inlet was observed to have no lava entering it but scattered incandescence in the webcam indicated that a north-going tube remained active (probably inflating) but not producing any breakouts. There must be two tube inlets on the north side and the active one must be out of view.
Seep-fed flows were still active producing slow-moving flows on the north and south flanks of the channel."
