Right

How big was the mountain then?

Alright, so, for the quake feat, the Impact must have been felt around 400 KM away considering that's how much the combined diameter of the entire range must be with 4KM wide mountains.

If it's enough to crumble houses, then it should be around magnitude 8.

So, putting that in the Earthquake calculation for distance gets us

(8)+1.1644+0.0048*400, which equals 11.0844.

Putting that in the formula for getting energy from Radiated Waves gets us

2.670545612191E21 Joules, 638.275719931141 Gigatons, Large Island level+
