A model is proposed in which the unresolved X-ray emission from the compact source observed in M87 arises from thermal radiation from a blast wave propagating through the ionized gas cloud in the galactic nucleus. It is assumed that this radiating shock wave was initiated as an isotropic explosion or bow-shock phenomenon as the jet and radio counterjet first emerged from the nuclear gas cloud. Time-dependent thermal X-ray flux spectra from the blast wave are calculated for a variety of initial conditions, and all but a few of these possibilities are eliminated by comparison with the observed X-ray fluxes at different energies. It is shown that the age and velocity of the nonthermal jet can be estimated from the age of the nuclear blast wave, provided a relationship exists between the blast wave and the jet. The results indicate that the details of the X-ray spectrum can best be fitted with an energy release of approximately 10 to the 56th power erg in a nuclear cloud with an electron density of about 100 per cu cm
