Genesis 19:25

And He overthrew those cities, and all the plain, and all the inhabitants of the cities, and that which grew upon the ground. It was a total destruction of the people with their cities and all their property, 2 Peter 2:6. And not only were all things above the ground consumed, together with all vegetation, but the very ground, which contained many asphalt pits and naphtha deposits, was burned out. It seems also that the Sea of the Plain sank together with the surrounding country, forming, with its extension, what is now known as the Dead Sea. To this day that entire country is a picture of utter desolation, with hardly a trace of animal or vegetable life. Sodom and Gomorrah, Admah and Zeboim, are an example of warning to the godless of all times. If they will not heed the Lord's call to repentance, they will find themselves engulfed on the last day in a cataclysm which will be a thousand fold greater than that of the vale of Siddim, casting them into everlasting destruction.
