Why do lava flows stop advancing? | Pacific Island National Parks

Paragraph very interesting about lava that's being produced at Pu'u O'o is still robust and also robust just before where it enters the crack.

If the flow slows down, lava farther along can begin to cool, thus causing a blockage in the tube structure.
lava may still be coming from the source, as it is here, but now gets forced out into what are called "breakouts" in the thinner portions of the tube structure. lava then flows out of those breakouts, further weakening the amount of the flow that would have gone straight to the front.
