We numerically compute the semiclassical probability of false vacuum decay at a nonzero temperature in the Schwarzschild space-time. We consider a four-dimensional model of a scalar field with toy potential. Our result suggests that if the temperature of the field equals that of the black hole, the decay proceeds via thermal activation mediated by sphalerons.
