Actually, the world won't experience the 7 last plagues of the 7 vials of God's wrath (Revelation chapters 15-16), the last stage of the future tribulation of Revelation chapters 6 to 18 and Matthew 24, until after the never-fulfilled Revelation chapters 6 to 15 have been fulfilled. At the first vial, an awful sore will appear on only those people who will have received the Antichrist's mark and worshipped his image (Revelation 16:2). At the 2nd vial, the sea will become like the blood of a dead man, and every living creature in the sea will die (Revelation 16:3). At the 3rd vial, all surface sources of fresh water will become blood (Revelation 16:4). At the 4th vial, men will be scorched with fire shot out from the sun (Revelation 16:8). This would be a solar-flare coronal mass ejection of solar plasma, which could make its way down to the surface of the earth due to the earth's magnetic field being disrupted during a magnetic-pole reversal which could occur near the end of the future tribulation.
At the 5th vial, the whole world will be plunged into literal darkness (Revelation 16:10). At the 6th vial, unclean spirits like frogs will come out of the mouths of Lucifer (the dragon, Satan: Revelation 12:9), and the Antichrist (the individual-man aspect of the beast), and the False Prophet (Revelation 16:13). And these unclean spirits like frogs will go forth and perform amazing miracles to convince the world's armies to gather together in an attempt to defeat YHWH God (Revelation 16:14, Revelation 19:19). The Euphrates will dry up so that the armies of "the kings of the east" (Revelation 16:12) (i.e. the vast armies of China, India, Pakistan, Japan, Iran, Indonesia) can easily cross the riverbed and gather at the "place" called Armageddon (Revelation 16:16) (Har Megiddo: Mount Megiddo in northern Israel). Once they have gathered there, as only a staging area, with all the other armies of the world (Revelation 16:14,16), they won't wage battle there (that's why the Bible doesn't refer to a "battle" of Armageddon). Instead, they will travel south to pillage Jerusalem, right before Jesus returns and defeats them (Zechariah 14:2-21, Revelation 19:19-21).
At the 7th vial, right before Jesus returns (Revelation 16:17,19, Revelation 19:2-21), there will be a huge earthquake which will affect the whole world (Revelation 16:18-20), and 100-pound hailstones will pummel the earth (Revelation 16:21). The 7th vial will also be when Revelation's symbolic (and worldwide) "Babylon" (Revelation chapters 17-18) will be destroyed (Revelation 16:19).
--
That is, Revelation's symbolic "Babylon" (Revelation chapters 17-18) represents all of mankind's corrupt political (Revelation 17:18), economic (Revelation 18:11), and religious (Revelation 18:24) systems throughout the earth (Revelation 18:3), and throughout history (Revelation 17:9-10). The 10 kings of the Antichrist's empire will destroy with fire what Revelation's "Babylon" represents (Revelation 17:16-17) when they destroy the cities of the earth (Revelation 16:19), probably with nukes (and probably with Fission-Fusion-Fission, "FFF", or "666", nukes, "F" representing the number six in English gematria), at the time of the 7th vial (Revelation 16:17,19), which will be the final event (Revelation 16:17) of the future tribulation of Revelation chapters 6 to 18 and Matthew 24, right before Jesus' 2nd coming (Revelation 19:2 to 20:6, Matthew 24:29-31). They could do this under the direction of Lucifer/Satan (Isaiah 14:17,12), who could want to leave only a literal "scorched earth" for Jesus to return to.
Near the very end of the future tribulation, Lucifer (employing the ancient lies of Gnosticism) could say to the Antichrist and his 10 kings something like: "Our great battle against the evil, tyrant god YHWH is about to begin [Revelation 16:14, Revelation 19:19], a battle which we will win, and so we will be able to escape YHWH's prison house, this material universe, and return to the wholly-spiritual Pleroma [i.e. Heaven]. So let us now destroy this prison cell, this foul planet, and let us, as it were, burn up all the gewgaws which we have hung upon our cell walls. Let us burn up all our great cities, all our magnificent systems. Let us break all our chains of attachment to this vile physical realm, that we might more freely ascend back to our rightful place in the Pleroma [Isaiah 14:13-14]".
Of course this will be a lie. For at his 2nd coming, Jesus (who is YHWH: John 10:30, Zechariah 14:3-4) will completely defeat the world's armies, arrayed against YHWH (Revelation 16:14, Revelation 19:19-21). And Jesus will have Lucifer bound in the bottomless pit during the subsequent 1,000 years (Revelation 20:1-6, Isaiah 14:15). And Jesus will restore ruined parts of the earth and make them like the Garden of Eden (Ezekiel 36:35, Isaiah 51:3). And after the 1,000 years and subsequent events are over (Revelation 20:7-15), God will create a new heaven (a new first heaven, a new sky/atmosphere for the earth) and a new earth (a new surface for the earth) (Revelation 21:1). And then God will descend from the 3rd heaven in the literal city of New Jerusalem, to live with saved humanity on the new earth (Revelation 21:2-4).
