This is my first calc of my Dark Shadow verse.
The Feat: Alexander and his team were fighting the "Masked Woman" when she decides to invoke a meteor and throw it against our heroes, but in an act of total courage (and looking for attention and recognition *cough cough*), Sophie launch with her hammer: not only stopping the meteor, but also, destroying it.
The Calc: So, from this page, Hong Kong has a Length of 36.017 km and a Width of 22.98 km
Volume of an ellipsoid = 9,933.884616507397 km^3 = 9,933,884,616,507.3 m^3
Mass = 2700 Kg/m^3 (Average density of meteors) * 9,933,884,616,507.3 m^3 = 2.68214885*10^16 Kg
The meteor is ablated so ablation speed for meteors is 2,000 m/s (minimum Ablation speed).
E = 0.5*(2.68214885)*10^16*(2,000^2) = 5.36429770*10^22 J = 12.8209792065 Teratons = Country level
And now, the Fragmentation value:
Fragmentation = 8 J/cc
Energy = (9,933,884,616,507.3 m^3)*1,000,000*8 = 7.94710769320584*10^19 J = 18.994 Gigatons
Final Tally: Sophie vs Meteor = 12.84 Teratons
Alexander and Leon are easily equal to Sophie. So they got scale from this.
