The expansion of hell melted the foundations of the mountains completely. There was now no support for the pillars of the earth and the crust of the earth collapsed.
It appears that the earth lost about 1,200 km of radius, and 8,000 km in circumference. Both of these concepts are part of the development of the theory of plate tectonics, they are referred to as radial shrinkage and circumferential shortening.
It is hard to imagine living through this event. Certainly we have not experienced anything this dramatic since it happened.
