Premise
DMUA thinks my other calc is low-balled (it isn't, but we'll go along with it). Instead of calcing the destruction of mountains, we will calculate it using a standard Earthquake calculation. For laughs.

Calc
Looking at this, it qualifies as roughly a XI on the scale, or a Magnitude 7 minimum. Fissures in the ground, big structures (mountains and local towns), the whole cataclysmic shindig.

The given area was about 7 hexes in total (See here for details) and about three hexes in diameter, meaning 90 miles, or 144.84 km.

Divide for a radius of 72.42 km.

(Magnitude at distance) + 1.1644 + 0.0048*r = 8.86 Magnitude at Epicenter

Looking at this, and solving the bottom equation, we get 1.230e18 Joules, or 293.98 Megatons of TNT. Mountain level for shattering many mountains.

And my calc was a lowball. Nice.

Tally
Versus Battles Standards Slaughter Tiers: 293.98 Megatons of TNT, Mountain level

I'm not downgrading based on this, just proving principle. I don't lowball unnecessarily.
