And unto Eber were born two sons: the name of one was Peleg; for in his days was the earth divided; and his brother’s name was Joktan.
( Genesis 10:25 ) KJV
The expansion of hell consumed the foundations of the mountains. That’s a way of saying that earth’s core became completely molten. The pillars of the earth lost their base of support. The mantle collapsed.
