No, they are two separate earthquakes and no vial pours until Christ returns. In fact the world is celebrating the two prophets deaths so no vials of wrath yet:
Rev 11:8 And their dead bodies shall lie in the street of the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified.
Rev 11:9 And they of the people and kindreds and tongues and nations shall see their dead bodies three days and an half, and shall not suffer their dead bodies to be put in graves.
Rev 11:10 And they that dwell upon the earth shall rejoice over them, and make merry, and shall send gifts one to another; because these two prophets tormented them that dwelt on the earth.
That relates directly to this:
Luk 17:26 And as it was in the days of Noe, so shall it be also in the days of the Son of man.
Luk 17:27 They did eat, they drank, they married wives, they were given in marriage, until the day that Noe entered into the ark, and the flood came, and destroyed them all.
Luk 17:28 Likewise also as it was in the days of Lot; they did eat, they drank, they bought, they sold, they planted, they builded;
Luk 17:29 But the same day that Lot went out of Sodom it rained fire and brimstone from heaven, and destroyed them all.
Luk 17:30 Even thus shall it be in the day when the Son of man is revealed.
Sorry but they are the same event. God pours out the 7 vials which will obviously stop this celebration party soon after it starts.
The 2 witnesses 1260 days is the same time period as the 42 months in chapter 13. Both events happen if the 7th Trumpet is interrupted.
1260 days is the same length of time roughly as 42 months. Which is also 3.5 years. This is the only absolute time mentioned in the whole book of Revelation besides the 5 months of the 5th Trumpet event.
Jesus and the 144k are on Mount Zion during this time, and not in Jerusalem. So only the two witnesses go through this 42 month period. They are the one's convincing those on the fence to be beheaded. That is their alter call. Otherwise they just destroy their enemies. Their message and death to their enemies is why those with the mark celebrate when they are finally allowed to be killed. But that celebration is indeed cut short when during those 3.5 days God's final wrath is poured out on them, because they rejected the testimony of those 2 witnesses.
"And they heard a great voice from heaven saying unto them, Come up hither. And they ascended up to heaven in a cloud; and their enemies beheld them. And the same hour was there a great earthquake, and the tenth part of the city fell, and in the earthquake were slain of men seven thousand."
"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."
Nothing in either passage contradict each other. They compliment each other in the over all perspective.
The point of contention is how John transitions back into the chronological narrative after the parenthetical about the 2 witnesses. Part of chapter 10 is already describing the 7th Trumpet. The 6th Trumpet is over even before the 7 Thunders. Revelation 11 is a parenthetical about the 7th Trumpet, not the 6th Trumpet. Chapter 12 is a parenthetical about the 7th Trumpet, not the 6th Trumpet. Chapter 13 is a parenthetical about the 7th Trumpet, not the 6th Trumpet. This verse does not mean what you think it does: Revelation 11:14
"The second woe is past; and, behold, the third woe cometh quickly."
All this verse does it get past the parenthetical and back to the chronological narrative. Of course the second woe is past. It was over back in Revelation 9:18-21
"By these three was the third part of men killed, by the fire, and by the smoke, and by the brimstone, which issued out of their mouths. For their power is in their mouth, and in their tails: for their tails were like unto serpents, and had heads, and with them they do hurt. And the rest of the men which were not killed by these plagues yet repented not of the works of their hands, that they should not worship devils, and idols of gold, and silver, and brass, and stone, and of wood: which neither can see, nor hear, nor walk: Neither repented they of their murders, nor of their sorceries, nor of their fornication, nor of their thefts."
This concluded the 6th Trumpet and the Second Woe. The next verses cover the 7 Thunders: Revelation 10:1-4
"And I saw another mighty angel come down from heaven, clothed with a cloud: and a rainbow was upon his head, and his face was as it were the sun, and his feet as pillars of fire: And he had in his hand a little book open: and he set his right foot upon the sea, and his left foot on the earth, And cried with a loud voice, as when a lion roareth: and when he had cried, seven thunders uttered their voices. And when the seven thunders had uttered their voices, I was about to write: and I heard a voice from heaven saying unto me, Seal up those things which the seven thunders uttered, and write them not."
All of this takes place before we are introduced to the 2 witnesses. The rest of chapter 10 deals with the 7th Trumpet. There is no going back to describe the 6th Trumpet, after chapter 9. This verse only gets our mind back into the chronological groove:
"The second woe is past; and, behold, the third woe cometh quickly."
This 3.5 year, or 42 month, or 1260 days described in Revelation 11, 12, and 13 is only dealing with the 7th Trumpet. Revelation 10:7
"But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets."
Every point John makes after this verse deals with the 7th Trumpet. John does not even declare a return at the 7th Trumpet unless you accept the 7th Trumpet is still sounding 42 months later at the battle of Armageddon. The 7th Trumpet starts sounding even before the parenthetical of Revelation 12-13.
"And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever."
Jesus and His angels along with the 144k just wrapped up the final harvest during the GT of the 6 Trumpets and 7 Thunders. The angels and Jesus arrived at the 6th Seal. Then the 144k were sealed. Then the 7th Seal was opened. Then the 6 Trumpets sounded, and then 7 Thunders were heard. The final harvest was during this time, however long or short. It cannot be defined as no one knows the day or hour the 6th Seal will be opened, and the Second Coming fulfilled. It could be months, weeks, or even days. But at least 5 months for the 5th Trumpet, which could extend into the 7 Thunders. No one is saying 5 months has to end, before the 6th Trumpet sounds.
Remember your verse though, the 7th Trumpet cannot sound until all the Trumpets and Thunders are over.
"The second woe is past; and, behold, the third woe cometh quickly."
The 7th Trumpet is not the 3rd Woe. The coming quickly part would be within 4 days of the start of the 7th Trumpet. The 7th Trumpet is a week long celebration. Daniel 9:27 is a week of days. The 7th Trumpet is a week of days. Revelation 10:7 declares the days of the sound of the 7th Trumpet.
The third woe is this week being split in half. That is the woe, not the 7th Trumpet itself. The confirmation of the Atonement Covenant by Jesus is the condition this woe is hanging on.
Satan being allowed 42 months is the woe of utter desolation. That the week cannot finish by the next Sunday is the 3rd Woe. When the 7th Trumpet sounds is when Satan and his angels are cast out of heaven. They only have 4 days at the most left. Satan is not automatically granted 42 months. It all could be over when the 7th Trumpet stops sounding, at the end of one week.
The only reason the week is put on hold, there are 2 witnesses, and Satan is allowed 42 months is that some humans will still choose God over Satan, even when Satan is in total control. Not even Satan can force people against their will, despite having sin natures. Some will still choose to be beheaded in spite of Satan's free reign on outright rebellion and wickedness against God.
The 7 vials are poured out at the end of the 42 months, because a deal is a deal. If Satan gets 42 months, God will not interfere at all during those 42 months. So the vials of God's wrath are only poured out after Satan is allowed to kill the 2 witnesses. God will work through 2 humans, but that is it. Revelation 17 and 18 just point out the wickedness allowed during these 42 months.
