What happens if an H-bomb detonates inside an active volcano?

Question

Just discussing this with a friend, and debating if an eruption would occur, and what kind

Answer 1

This will accelerate the process.

Answer 2

It would do what any other thermonuclear device would do. Emit heat, light and radiation plus a colossal blast wave. This would take the crater out and the volcano's contribution to the fireworks would be to provide radioactive dust and debris to be propelled high up into the stratosphere.  Can we have a more cheerful question next time?
