It looks like there is a small volume that turns to liquid and then possibly gas at a rate faster than the surrounding material, creating an expanding volume. The craters we see point outward from the surface of the substrate, and I would expect the surface side of the molten volume to exert less pressure on the volume than the opposing side. This in turn leads an eruption away from the inner wall and towards the surface. In this model, the momenta of the original sources of heat do not play a part. Eric
