'' Moreover, the lower the mass of the black hole, the higher its temperature. so as the black hole loses mass, its temperature and rate of emission increases, so it loses mass more quickly. what happens when the mass of the black hole eventually becomes extremely small is not quite clear, but the most reasonable guess is that it would disappear completely in a tremendous final burst of emission, equivalent to the explosion of millions of H-bombs."

According to Hawking, a black hole loses its mass continually and coming from him it's most probably true.

According to me the final explosion may not happen at all. When the black hole loses its mass, the surface area of the event horizon will decrease gradually. There will be a certain mass that the black hole will have at a time that the event horizon will no longer exist. Which will also mean that the super strong gravitational field of the black hole will also decrease to a point that all particles including light and other radiation will be able to escape. At this point, the black hole will no longer be one. My point is that when the black hole loses its mass, the strong gravitational force will decrease and that the former black hole will become just a big chunk of rock floating in space.

Well, that's my point of view. Other suggestion are welcome.
 
I think that the rate of emission, relative to its size, of a black hole increases as the size decreases. So I think that Hawking is assuming an exponential (?) cascade of this escalating effect once the size of the black hole was quite small.

If you consider that all of the mass ends up creating a blast that is equivalent to "only" millions of H bombs, you get a hint that it is not so very massive at all. Consider that in an H bomb, only a very small amount of mass is really converted into energy.
