Hiding in a hole isn't a good plan.
As an extermination level impact (Multi Gigaton) will cause;
(1) A planet circling surface blast wave just like you see in all the old nuclear test footage.
(2) Sub-surface seismic shock waves causing global double digit level earthquakes and all live volcanoes to erupt as the planetary crust quite literally rearranges itself like ping-pong balls on a swimming pool.
Fast forward 10,000+ years and the surface may be liveable again unless the impact manages to breach the crust in which case it could take millions of years to recover.
The only way of avoiding these events is to 'Be somewhere else when it happens' and generally speaking I think about 99% of humanity would like the option of dodging the bullet.
