In a hydrostatic test, the energy available for an explosion comes from the stretching of the tank material and the compressibility of the water (which is minuscule). I can imagine there's enough stretch in a scuba tank at what, 3000 psi or so?, to make the water squirt out of a leak with a fair bit of force. At 100 psi, though, as with air compressors and old-time boilers, I don't think there's much energy stored in tank stretching.
