Even if a volcano does not appear to be active at the surface, it could still overlie a magmatic anomaly.

This approach was recently used to estimate the seismic of the Yellowstone magmatic body. See this paper: http://onlinelibrary.wiley.com/doi/10.1002/2014GL059588/abstract

Seismic tomography can theoretically be applied to any region, but we just need to have enough seismic sources nearby (e.g. earthquakes) to be able to do this accurately.

Long-wavelength electromagnetic methods, like magnetotellurics, might also be able to detect the electrical conductivity anomaly associated with the magma chamber (though there are some restrictions). See this classic paper by Newman et al. (1985).
