To answer your question regarding the impact force of a Wurm burrowing through a mountain, allow me to clarify:

Wurms do not burrow through boulders. They shatter boulders. Ergo, it stands to reason that Wurms do not burrow through mountains, at least in the traditional sense of digging with their claws.

Rather, they shatter the very foundations of the mountain itself to get to you. Suffice to say, the tensile strength of Wurm scales and skin is very high, indeed.
