Educate me on the formation of lava tubes. I had thought that they formed under the recently cooled crust of the lava and there after allowed the lava underneith to move much faster by insulating it. So, wouldn't the slow moving surface lava have to reach a particular point before a lave tube could form to move quantities of lava there quickly? If so, then we are still waiting for the slow moving flow to make the surface journey 7 miles to Pahoa, Rt 130 or my lot before a tube could form to that point. Or do tubes burrow underground ahead of the surface flow?
