10 to the 28 power mega-tons is what Google says about the yield of a supernova

The maximum yield of the tsar Bomba was actually a hundred megatons they cut it in half because they didn’t want to risk significant damage

To answer the actual question, your average supernova emits an estimated 1–2·10⁴⁴ Joules of energy, which is equivalent to approximately 2.4–4.8·10²⁸ megatons of TNT, or about 24—48 octillion tons. This would be equivalent to the energy generated from a mass 10¹² (one trillion) times that of Earth, which is approximately 5.972·10²⁴ kilograms. For reference, a solar mass (a mass equal to 1 Sun) is about 1.989·10³⁰ kg. The Sun accounts for 99.86% of all of the mass of the Solar System which is an estimated 1.0014 solar masses

For those that don’t know or understand how exponents work, keep in mind that the difference between 10⁹ and 10¹⁰ is ten times, so 10¹⁰ is ten times more than 10⁹, one hundred times more than 10⁸ and so on up the chain.

A star (or really most stellar object) needs to move into a threshold of 8–15 solar masses before it can be capable of going supernova. The reason supernovae happen is because of all that extra mass collapsing in on itself due to gravitational force. A star produces nuclear fusion it it’s core and the energy produces pressure that counteracts gravity. That pressure condenses the outer layers of the star and it runs out of hydrogen in those layers, it uses the hydrogen deeper in its core; this causes the outer layers to expand as it cools, this expanding into a red giant. When the star runs out of hydrogen, it starts using the helium to continue further nuclear reaction, then further elements until it gets to iron, from which it can’t decay further. There is no more reaction to be had and this the pressure is superseded by the gravitational forces.

A star the size of our Sun will simply eject the outer layers when it runs out of fuel while a star that meets the above threshold will collapse back on itself and the resulting force of this causes a monumental release of energy. Depending on the size of the star, it will become one of a few class of either neutron star or black hole.

In other words: Forget the Sun; there is literally not enough mass within the entire solar system that comes anywhere remotely close to equaling what’s required for the power of a supernova, which mind you briefly outshines entire galaxies during it’s duration.

I got a little off track, but that’s about the answer the the question of “what yield is a supernova”. The sun can’t go supernova, it doesn’t have enough mass, but hypothetically if it could, the answer would probably be about the same as the amount of energy it’s emitted in it’s entire lifetime.

I’m sure someone will critique my wall of text and find errors, and please do. I won’t learn otherwise and I admit my research was sloppy.

Or a naughty little chicken?

I pick Option C: A Timelord before morning espresso.

remember the kurzgesagt video about all the nukes? tia is bigger than that nuke cube.

A F or G rate star is not massive enough to go supernova, as JP said.  
Still, just by definition, it has more power than anything a pre-type I civilization can achieve.

@Background Pony #201B  
Actually the full scene DOES show the mountains moving

@Barhandar  
To be fair an earthquake wouldn’t make mountains “wiggle” either. To me it looks like a visual representation of air ripple from the sheer pressure of the sound waves, rather than a literal ripple in the rock of the mountains and hills.  
I haven’t heard about terraforming with bombs, though. Can that really be useful, unless you specifically want a glassed wasteland? I suppose you could create a nuclear winter too, but that’s not really a very desirable effect.

@Barhandar  
Plus it’s confirmed that Equestrian Magic is the source for Pinkie’s Toon Force

@Background Pony #201B  
Would camera shake make clouds move away and mountains wiggle?  
Also a stronger bomb would absolutely be useful for terraforming, but we haven’t reached the level where we’d need that yet.

@Barhandar  
To be fair the only reason a bigger bomb hasn’t been built is because there’s no need. It’s very difficult to test (Tsar Bomba was engineered for 100MT, and then halved just to make testing it less dangerous, and the planes that dropped it were still at risk), and it’s not actually useful as a weapon - only as a publicity stunt (tactical missiles, with medium yield warheads, are much, much more cost-efficient, easier to use, etc.).
 
@Macaroni C-Pony  
A camera shake is [i]much[/i] more plausible than an earthquake, so while that is a fun analysis I’d say it’s too fundamentally flawed to take seriously.

Have you heard of the child called Anti-Matter?

I just realized, she could just set the sun on a crash course to Earth, Therefore ending all life on the planet and disrupting the entire solar system.

One is guaranteed to kill you. The other has a high probably of bringing you back.

She pretty much can make the human race go extinct.

Even Pinkie Pie is stronger than a nuclear bomb according to these calcs

Why not both

@ABronyAccount  
For maximum hilarity, the strongest explosion humanity has triggered isn’t even the most powerful explosion that was sourced to Earth’s surface - that would be Krakatoa, about 200 megatons of instantanteous energy release.

Well, They did it with the moon
 

@Fwelin  
When has logic ever applied in MLP? We’re talking about a world where an energy source that defies the laws of physics standing in as the life force behind all living things in the multiverse.

WHO WOULD WIN:
 
The most powerful destructive force mankind has ever unleashed

Ceci n’est pas une pipe alicorn.

The MLP sun does not work like ours, and I would honestly not be surprised if all magic could do to it is move it around the planet at a predetermined distance (I am aware that there was an old, old statement by one of the showrunners that their sun is like our own, but that’s crazy iffy just based on how much it’s properties are contradicted in the show). Even when Twilight was moving the sun and moon with minimal control in TK and BDaD, they never once got closer or farther than normal. Either that, or the sun and moon aren’t actually physical objects, but rather magical projections on the sky that generate day and night (which is apparently more than just the lack of day in Equestria).
 
Rapid changes in the sun’s position don’t seem to have any negative effects on orbits or gravitational effects, so it doesn’t seem to control that, either.
 
Finally, the sun might not even generate heat; Celestia moving the sun to directly overhead did not come up as a temporary option during The Crystalling, and eternal night in NMM’s bad timeline didn’t seem to make the area any colder despite being like that for years, so it seems likely that the sun does nothing in Equestria by generate light, with heat generated by some other means.
 
So, I think it’s entirely likely (though not guaranteed) that the bomb is more dangerous even with Celestia having control of the sun.
