This is pretty much how I understand things. The 7th plague is the last plague as told in Rev 15:1. I would like to emphasize the gathering of the nations in verse 16 above, the voices thunders and lightnings with an earthquake in verse 18, the hail in verse 21, and the fact that these things are specifically the wrath of God; as these things/this last plague is repeated 6 times in chapters 6-19 of the Revelation.
1) Rev 6:14b-17
14...every mountain and island were moved out of their places. (Earthquake)
15 And the kings of the earth, and the great men, and the rich men, and the chief captains, and the mighty men, and every bondman, and every free man, hid themselves in the dens and in the rocks of the mountains; (Gathering)
16 And said to the mountains and rocks, Fall on us, and hide us from the face of him that sitteth on the throne, and from the wrath of the Lamb:
17 For the great day of his wrath is come; and who shall be able to stand? (Wrath)
2) Rev 8:5 "And the angel took the censer, and filled it with fire of the altar, and cast it into the earth: and there were voices, and thunderings, and lightnings, and an earthquake." (voices, thunderings, lightnings, earthquake)
3) Rev 11:18-19
18 And the nations were angry, and thy wrath is come, and the time of the dead, that they should be judged, and that thou shouldest give reward unto thy servants the prophets, and to the saints, and them that fear thy name, small and great; and shouldest destroy them which destroy the earth. (Wrath, Gathering)
19 And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail. (lightnings, voices, thunderings, earthquake, hail)
4) Rev 14:19-20
19 And the angel thrust in his sickle into the earth, and gathered the vine of the earth, and cast it into the great winepress of the wrath of God. (Wrath)
20 And the winepress was trodden without the city, and blood came out of the winepress, even unto the horse bridles, by the space of a thousand and six hundred furlongs. (Gathering)
5) These are the Rev 16 verses above
6) Rev 19:15-19
15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God. (Wrath)
16 And he hath on his vesture and on his thigh a name written, King Of Kings, And Lord Of Lords.
17 And I saw an angel standing in the sun; and he cried with a loud voice, saying to all the fowls that fly in the midst of heaven, Come and gather yourselves together unto the supper of the great God;
18 That ye may eat the flesh of kings, and the flesh of captains, and the flesh of mighty men, and the flesh of horses, and of them that sit on them, and the flesh of all men, both free and bond, both small and great.
19 And I saw the beast, and the kings of the earth, and their armies, gathered together to make war against him that sat on the horse, and against his army. (Gathering)
I assume the falling mountains and the hail are the winepress used on the gathering.

Very good, will look it up. Now notice how it refers to a gathering of two differing classes of people as well as spirits of evil against good.
There is a gathering and we see it is demon spirits which work miracles before the leaders of the earth and before the whole world and gather them for the battle against God.
Revelation 16:13-14
13 And I saw
three unclean spirits like frogs come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet. 14 For they are the spirits of devils, working miracles, which go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.
We see in the Bible what is a final separation of the righteous saints from the wicked, a gathering of the righteous for salvation and deliverance by Christ and His angels, and the gathering of the rebellious wicked to be slain when they fight at this battle. We see more description in Revelation 17 and 19.
Revelation 17:14
12 And the ten horns which thou sawest are ten kings, which have received no kingdom as yet; but receive power as kings one hour with the beast.
13 These have one mind, and shall give their power and strength unto the beast.
14 These shall make war with the Lamb, and the Lamb shall overcome them: for he is
Lord of lords, and King of kings: and they that are with him are called, and chosen, and faithful.
Revelation 19:16
11 And I saw heaven opened, and behold a white horse; and he that sat upon him was called Faithful and True, and in righteousness he doth judge and make war.
12 His eyes were as a flame of fire, and on his head were many crowns; and he had a name written, that no man knew, but he himself.
13 And he was clothed with a vesture dipped in blood: and his name is called The Word of God.
14 And the armies which were in heaven followed him upon white horses, clothed in fine linen, white and clean.
15 And out of his mouth goeth a sharp sword, that with it he should smite the nations: and he shall rule them with a rod of iron: and he treadeth the winepress of the fierceness and wrath of Almighty God.
16 And he hath on his vesture and on his thigh a name written,
King Of Kings, And Lord Of Lords.
We see a similar theme in Zephaniah when God's people are assembled in the day of the Lord.
Zephaniah 2:3
1
Gather yourselves together, yea, gather together, O nation not desired;
2 Before the decree bring forth, before the day pass as the chaff, before the fierce anger of the Lord come upon you, before the day of the Lord's anger come upon you.
3 Seek ye the Lord, all ye meek of the earth, which have wrought his judgment; seek righteousness, seek meekness: it may be
ye shall be hid in the day of the Lord's anger.
This battle of the day of the Lord is a development of Gods wrath on the rebellious wicked is presented under what is the symbolic name of Armageddon. The meaning of the word, as evident in the description of the battle itself, is not conclusive, except that all derivations of the word point to the general meaning of gathering or assembling. Let take a look..
Megiddo. This may be a possible reference to the ancient city of Megiddo with a Canaanite fortress at the foot of the Carmel range and was famous as a battlefield down through the centuries, and thus could be a place for "gathering" or "assembling" of armies for attack.
Mount of Megiddo. Here
megiddo is assigned the meaning of "the place of God". Thus
har (mountain) and
megiddo ("place of God") would signify "mountain of the place of God," which makes it basically "the mount of the congregation," where God dwells in heaven.
We see it used in reference to where Lucifer, the devil, seeks to ascend or wants to gain, in Isaiah..
Isaiah 14:12-15
12 How art thou fallen from heaven, O Lucifer, son of the morning! how art thou cut down to the ground, which didst weaken the nations!
13 For thou hast said in thine heart, I will ascend into heaven, I will exalt my throne above the stars of God: I will sit also upon
the mount of the congregation, in the sides of the north:
14 I will ascend above the heights of the clouds; I will be like the most High.
15 Yet thou shalt be brought down to hell, to the sides of the pit.
So we have evil spirits whose leader we know is Satan, assembling of the kings of the earth and the wicked, and as we see it is not necessarily a physical gathering of the armies of the world into one spot on earth, but a battle which involves them against the saints, and the Lord, the King of Kings, Jesus at the Second Coming.
