Revelation:
In the book of Revelation is the description of an earthquake of unprecedented size during the pouring out of Gods Wrath:

Rev 16: 18-21
18 And there were voices, and thunders, and lightnings; and there was a great earthquake, such as was not since men were upon the earth, so mighty an earthquake, and so great.
19 And the great city was divided into three parts, and the cities of the nations fell: and great Babylon came in remembrance before God, to give unto her the cup of the wine of the fierceness of his wrath.
20 And every island fled away, and the mountains were not found.
21 And there fell upon men a great hail out of heaven, every stone about the weight of a talent: and men blasphemed God because of the plague of the hail; for the plague thereof was exceeding great.

I included verse 21 here because this I believe to be relevant. In John Mac Arthur's study Bible he makes mention of Chapter 21 as being an event where perhaps there was some type of volcanic activity, possibly with water included, such as under sea volcanic activity, but lets go back to the description of this great earthquake, then I believe we can solve verse 21.
