Level 70
I'm not sure but I think Tyranitar learns Earthquake after evolution.
Yes, Tyranitar can learn Earthquake via leveling up or using a TM. Earthquake is a powerful Ground-type move that complements Tyranitar's Rock and Dark-type moves in battle.
It learns Hyper beam on lv. 57.
yes
Tyranitar learns Hyper Beam at level 73.
Don't think there is one, but, larvatar --> Pupitar --> Tyranitar
Tyranitar cannot naturally learn Dig, but it can be taught Dig through a TM.
you have to give typhlosion a TM Earthquake Hopes this helped :-D
Evolve it from larvitar at level 30 to evolve it into pupitar then evolve it into tyranitar at level 55
