Hmmmm. Okay, brainstorm. The capping idea seems like a good way to build up pressure. So does adding water and triggering an earthquake. Maybe some combination of those?
Also, is this accidental or intentional?
If you had a volcano that was being tapped for heat energy, via magical or sientific means - drawing off the heat to fuel something or other, for instance - I mean that's what powerplants really are, isn't it? Producing energy through combustion? So, use the heat energy from the volcano. Now, if that draw got looped back to the volcano, or something like backlashed, if the spell broke, it could stuff a lot of energy back into the volcano in too short a time, causing a buildup of energy/heat, thus pressure, especially if the volcano is either capped, naturally closed, or becomes that way somehow.
Or, sci-fi here, if a large energy source (yes, nuclear type thing), like, say, an alien spacecraft, was to either end up in a volcano or have been there for a few thousand/million years and the shields finally failed or the hull got eaten through or whatever, and the power core got shorted out by the magma, that might again trigger pressure/energy increase.
Hmmm. The earth's surface is basically under a sea of air. Now, I don't know that this is possible, since I don't know how much pressure the air actually puts on the surface, but if you had something like a giant, non-physical(or maybe physical)... hickey machine. ^.^;;; That sucked all the air off the top of a volcano and broke the top off the now-active volcano to boot? It would also be a pressure differential then, like explosive decompression from a spaceship airlock. Uh, unless the gravity of the earth counteracted that. Yeah, I have no idea, just tossing out wild theories here. ^.^;;;;

So anyhow, that's my input. ^.^;
