[quote=@Cyclone] I hadn't really considered that, but this lava was highly viscous, denser and heavier than other liquids like water, and deep enough for Torrens to be wading through. I'm no physicist but I'll just roll with what I've already written; it obviously depends on how strong the bomb is, but I think it's reasonable to say that most of the lava remained. [/quote] Sounds reasonable.
