No, we dont have a bomb which would destroy the whole world. The world is big. The energy of a large earthquake is far, far more than any nuclear weapon, and how much damage does that do a few hundred km away?......
A hydrogen bomb is a fusion bomb. It uses the opposite reaction, the fusing of hydrogen nuclei into larger nuclei. That's the reaction that drives the sun.
There's a chart of "yield" (explosive power) here.

It does show H-bombs as being among the largest-yield bombs built, but I think nevertheless the arsenals of nuclear powers tend to be made of fission bombs. I think that has to do with other practicalities besides just trying to get one warhead with as big a yield as possible.

An atom bomb uses uranium. In uranium, some atoms will spontaneously break down, releasing energy. When they do they emit particles that can break other atoms (fission). If enough atoms are near each other (called critical mass) the fission will continue out of control.
A hydrogen bomb uses the energy of an atomic bomb to force hydrogen atoms together, fusing them into helium atoms (fusion), releasing energy.
Hydrogen bombs are usually far more powerful.
Look up the difference between a Fission & Fusion bomb...
