The Seventh Vial

The Seventh Vial
The Earth utterly Shaken
And the seventh angel poured out his vial into the air; and there came a great Voice out of the Temple of Heaven, from the Throne, saying, It is done.
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.
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.
And every island fled away, and the mountains were not found.
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.
Rev 16:17-21 KJV
When the seventh angel pours out the Seventh Bowl of God's Wrath, the great city Babylon will be destroyed, for GOD ALMIGHTY remembers her and gives her the cup filled with the wine of the fury of His Wrath.
The great city split into three parts, and the cities of the nations collapsed. God remembered Babylon the Great and gave her the cup filled with the wine of the fury of His Wrath (v.19 NIV)
This will be the most severe earthquake the Earth has ever endured. Entire cities will fall at its power, mountains will be flattened. The Earth will be completely changed as a result of this earthquake’s ministry.
The impending fall of Babylon the Great was long announced in Revelation 14:8.

The Seven Vials will serve as a third woe upon the Earth—a completion of God's Wrath. First and second woes are recorded in Revelation 9:1-12 and 11:1-14 respectively.
In the Seventh Trumpet (Revelation 11), Christ’s Reign is foreseen, but in the Seventh Vial there will be a great shaking of the Earth.
In the Seventh Trumpet, the divine Authority, Dominion, Kingdom, Sovereignty, and Rule of Christ is announced—the kingdom of this world becomes the Kingdom of our Lord and of His Christ.
In the Seventh Vial, Babylon the Great comes in remembrance before God so to make way for His Wrath to have full effect upon her.

In the sounding of the Seventh Trumpet are loud voices heard from Heaven with flashes of lightning, rumblings, peals of thunder, an earthquake and a great hailstorm, as God's Temple and the Ark of the Covenant is seen.

But, when the seventh angel pours out the Seventh Vial, a great Voice out of the Temple of Heaven will be heard, and voices, and thunders, and flashes of lightning—and there will be a mighty earthquake and a great plague on the Earth.
