The meteorite that wiped out the dinosaurs lands right on Garterbelt and he survives it. That at minimum would be 100 teratons, but here it and it's effects look even greater. Diameter of the Earth is 12756.2km, or 12756200m.
1 pixel = 12756200m/2135 = 5974.80094m
5974.80094m X 677 = 4044940.24m
4044940.24m/670 = 6037.22424m
6037.22424m X 1195 = 7214482.97m
7214482.97m/2 = 3607241.48m
4044940.24m/2 = 2022470.12m
T = 3607241.48m/2.96s
= 1218662.66m/s
Volume as an ellipsoid.
V = 4/3πabc
= 4/3 X π X 2022470.12 X 3607241.48 X 3607241.48
= 1.10235419e20m^3
Weight of a dustcloud/air is 1.003kg per m^3.
M = 1.003 X 1.10235419e20
= 1.10566125e20kg
Finally, let's get our energy.
KE = (0.5)mv^2
= (0.5) X 1.10566125e20 X 1218662.66^2
= 8.21030144e31 joules
= 19.623091395793498037 zettatons
Final Results
Meteor hits Garterbelt = 19.623 zettatons
Consistent with Stocking getting jitzed on by the Moon.
