Whether the fire of hell is beneath the earth?

Objections

Objection 1 : It would seem that this fire is not beneath the earth. For it is said of the damned (Job 18:18), "And God shall remove him out of the globe [Douay: 'world']." Therefore the fire whereby the damned will be punished is not beneath the earth but outside the globe.
Objection 2 : Further, nothing violent or accidental can be everlasting. But this fire will be in hell for ever. Therefore it will be there, not by force but naturally. Now fire cannot be under the earth save by violence. Therefore the fire of hell is not beneath the earth.
Objection 3 : Further, after the day of judgment the bodies of all the damned will be tormented in hell. Now those bodies will fill a place. Consequently, since the multitude of the damned will be exceeding great, for "the number of fools is infinite" (Eccles. 1:15), the space containing that fire must also be exceeding great. But it would seem unreasonable to say that there is so great a hollow within the earth, since all the parts of the earth naturally tend to the center. Therefore that fire will not be beneath the earth.
Objection 4 : Further, "By what things a man sinneth, by the same also he is tormented" (Wis. 11:17). But the wicked have sinned on the earth. Therefore the fire that punishes them should not be under the earth.
