User blog:ThePerpetual/Request 16: An Earthquake Except Way Bigger

(For Komodo25M.)

So apparently, someone made an earthquake strong enough, that everyone on the planet they were on would be able to feel it. Thing is? Said planet was 100 times the size of Jupiter.

How that would work at all is beyond me, but I'm not one to question the logic that goes into fiction, so

(Thanks, VsBW, for Earthquake Math)

Basically, what we're looking at- if its clearly felt by people on the other side of the world, but nothing more- is a relative magnitude 3.0 earthquake... at that distance. That's the thing: how actually potent is it at its epicenter?

We'll need the diameter of the planet: which is 100 times that of Jupiter's (~133708 km, at its lowest), or 13370800 km.

Now, plugging that into our Earthquake Equation, if the Magnitude is at 3.0 all the way over there, then at its epicenter, the true Magnitude would be...

3 +6.399 + 1.66 * (log10((13370800/110)*((2*π)/360))) = 16.58123

And with that Magnitude, we can find the energy yield in Joules:

10^((1.5*16.58123) + 4.8) = 4.69726e+29 Joules, or 112.267 Exatons of TNT equivalent; Moon level, about 3.8 times baseline.

...and that's about it.

Final Tally
Really Strong Earthquake
 * Attack Potency: 112.267 Exatons of TNT
