What would be the effect of a powerful explosive going off in the core of a planet?

What would happen if a powerful explosive went off in the core of a planet?

On Earth, you have several layers of the planet, the crust, the magma, the outer core, and the inner core. Right now, human technology can't really get past the crust. But say an alien civilization came that could get all the way to the inner core.

So this alien civilization comes and uses their technology to plant a powerful explosive, say at least as powerful as a Fusion bomb, in the inner core. What would happen?

And for a bonus, what would happen if an explosive with three times the power of a fusion bomb went off in the core?
