Sounds like the rock is riddled through with fractures. Weakening the whole mountain

Is there a difference between "tired" amd "stressed" in this context?
the word they're looking for is fatigued

https://en.wikipedia.org/wiki/Fatigue_(material)

Which is French for tired.
It's more like "fatigue" in the materials science context.

Subterranean nuclear testing produced rock fatigue from the unusual stresses and strains.

It's one of the few geologically detectable effects of the anthropocene era, like increased atmospheric CO2, and the discontinuity in the baseline C-14/C-12 ratio. If human civilization were to be erased from Earth, a future researcher would still be able to determine that at some point, something dug up carbon fuels and burned them for power, and at a somewhat later point, something detonated nuclear weapons in the open atmosphere, and in underground tests.

Potentially. Stressed could mean something is being pushed to the limit, but not exhibiting performance degradation yet.

Where as tired could imply performance degradation is already happening.

Obviously this isn't that precise, but it's my personal interpretation.

In other materials not much stress is needed once a material is tired. Happens to steel if it gets bent a lot.
Stress is an engineering term that refers to internal force. It would not apply to this description.
