Because that is something that cannot be known.
This is at the beginning of the Tribulation. At this point only five judgments have been unleashed. Those who try to make the Seals, Trumpets, and Vials all the same judgments run into some obvious problems. They fail to maintain thee fairly easy to follow timeline given in Revelation.

Rev 6:12-14
12 And I beheld when he had opened the sixth seal, and, lo, there was a great earthquake; and the sun became black as sackcloth of hair, and the moon became as blood;
13 And the stars of heaven fell unto the earth, even as a fig tree casteth her untimely figs, when she is shaken of a mighty wind.
14 And the heaven departed as a scroll when it is rolled together; and every mountain and island were moved out of their places.
KJV
Part of Rev.6:12 and all of Rev.6:13 are tribulation events, but not Rev.6:14 and thereafter to the end of that Rev.6 chapter. Here's the parallel to the verse 14 6th Seal events, which below are 7th Vial events...
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.
20And 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.
KJV
Notice when this Isaiah 13 Scripture puts that time of the sun being darkened with that "day of the LORD" coming. Another parallel Scripture is Joel 2:31...
Isa 13:9-11
9 Behold, the day of the LORD cometh, cruel both with wrath and fierce anger, to lay the land desolate: and He shall destroy the sinners thereof out of it.
10 For the stars of heaven and the constellations thereof shall not give their light: the sun shall be darkened in his going forth, and the moon shall not cause her light to shine.
11 And I will punish the world for their evil, and the wicked for their iniquity; and I will cause the arrogancy of the proud to cease, and will lay low the haughtiness of the terrible.
KJV
Now the "day of the LORD" is NOT the great tribulation timing that our Lord Jesus and His Apostles taught (Matt.24; 1 Thess.5; 2 Pet.3:10; 2 Thess.2). Instead, the "day of the Lord" is the FINAL day of this present world, and will END the great tribulation with Jesus' second coming. THAT... is when our Lord Jesus will gather His Church, on that day. That is the last day, the day of the resurrection also, the sounding of the final trumpet. It is also when the battle of Armageddon will occur.
I know you guys have been taught to look at the plagues in the Vials and treat that as this specific day of God's cup of wrath being poured out upon the wicked, but the OT prophets make a distinction with God's wrath that is poured out on the specific "day of the Lord" timing, and that is the wrath that Apostle Paul was teaching about in 1 Thess.5 that we are not appointed to. The wrath in the other Vials are not for us either, but it's this particular "day of the Lord" wrath that Paul was speaking of, because this "day of the Lord" is the specific timeline subject Paul is covering in 1 Thess.5.
Joel 3:12-17
12 Let the heathen be wakened, and come up to the valley of Jehoshaphat: for there will I sit to judge all the heathen round about.
13 Put ye in the sickle, for the harvest is ripe: come, get you down; for the press is full, the fats overflow; for their wickedness is great.
14 Multitudes, multitudes in the valley of decision: for the day of the LORD is near in the valley of decision.
15 The sun and the moon shall be darkened, and the stars shall withdraw their shining.
16 The LORD also shall roar out of Zion, and utter his voice from Jerusalem; and the heavens and the earth shall shake: but the LORD will be the hope of his people, and the strength of the children of Israel.
17 So shall ye know that I am the LORD your God dwelling in Zion, My holy mountain: then shall Jerusalem be holy, and there shall no strangers pass through her any more.
KJV
Those events are about the "day of the Lord" when God will gather the nations around Jerusalem in order to pour out His cup of wrath upon them. That is the Armageddon timing our Lord Jesus foretold at the end of Rev.16 on the 7th Vial events. But Joel 3:16-17 is the specific time of the "day of the Lord" with Christ's second coming to do battle against those nations on the last day.
Rev 16:16-20
16 And he gathered them together into a place called in the Hebrew tongue Armageddon.
17 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.
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.
KJV
Those above events parallel with what our Lord Jesus said in Matt.24...
Matt 24:29-31
29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
31 And He shall send his angels with a great sound of a trumpet, and they shall gather together His elect from the four winds, from one end of heaven to the other.
KJV
And then here's a huge parallel from Isaiah 2 that also shows what timing the Rev.6:15-17 verses are...
Isa 2:12-19
12 For the day of the LORD of hosts shall be upon every one that is proud and lofty, and upon every one that is lifted up; and he shall be brought low:
13 And upon all the cedars of Lebanon, that are high and lifted up, and upon all the oaks of Bashan,
14 And upon all the high mountains, and upon all the hills that are lifted up,
15 And upon every high tower, and upon every fenced wall,
16 And upon all the ships of Tarshish, and upon all pleasant pictures.
17 And the loftiness of man shall be bowed down, and the haughtiness of men shall be made low: and the LORD alone shall be exalted in that day.
18 And the idols he shall utterly abolish.
19 And they shall go into the holes of the rocks, and into the caves of the earth, for fear of the LORD, and for the glory of His majesty, when He ariseth to shake terribly the earth.
KJV
As I have shown elsewhere, when the wicked try to hide from The Father and His Son on that day, it is because of the time of His wrath upon them. That's why they seek to go into the holes of the rocks and caves, "for fear of the LORD", and "for the glory of His majesty" which means Jesus coming in Glory, which is definitely the time when "He ariseth to shake terribly the earth".
The Tribulation is God's wrath poured out, not Satan's. It is the Seventieth Week of Daniel, and while Satan does seek to persecute those who are saved, you give him too much credit and erroneously depict him ads being in control.
