Will a nuke set off a volcano?

Answer 1

Probably not. A volcano has a relatively large rock plug that would be very resistant to a nuclear blast. However, some volcanos that have a thinner plug, or a VERY big ground-penetrating nuke could possibly set off a volcano.

Answer 2

No, a nuclear explosion is not powerful enough to trigger a volcanic eruption. Volcanic eruptions are driven by the movement of magma beneath the Earth's surface, which is a natural process that is not directly influenced by nuclear detonations.
