In answer to the question above, I don't think the previous Kapoho flow was as a result of a tube. I think what happened was the ground just tore itself apart and lava started spewing out in great, gigantic fountains.
So, far that is not what is happening here. Pele found an "outlet" and has been expressing herself fairly calmly through that outlet. I look at it as if she is singing, very, very loud, at the top of her range, but it is still controlled, and she is not angry. She is just, for lack of a better word, venting.
I do think tubes are important to this eruption.
I guess there are tubes all under Kilauea. I have been trying to get information on that, but it appears to me that the tube system has not been fully mapped as of yet. That is a labor intensive job, that could take years and would be very dangerous. All of the subdivisions have tubes under them somewhere, I think. I know HPP does. The entire landscape does. If this lava enters the tube system --that is, if it connects with other tubes-- this could get interesting.
I don't recall HVO discussing this "tube" system I just mentioned. They seem to presume that it will take a surface route if it goes anywhere. In any case, it has dropped in elevation. My bet is a crossing north of the Pahoa-Kalapana road. I say that because this is NOT on the Southside of the ridge. It won't go over the ridge. The flow will go with the terrain.
