John and Doves,
The 6th seal is Gog/Magog battle. There are many resemblance between Revelation 6:12-17 and Ezekiel 38:19-23.
1/ Revelation 6:12 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;vsEzekiel 38:19 For in my jealousy and in the fire of my wrath have I spoken, Surely in that day there shall be a great shaking in the land of Israel;
John and Ezekiel both saw a great shaking.
2/ Revelation 6:13 And the stars of heaven fell unto the earth,vsEzekiel 38:22 I will rain upon him, and upon his bands, and upon the many people that are with him, an overflowing rain, and great hailstones, fire, and brimstone
Stars of heaven, hailstones, and brimstone, are missiles and meteorites which will be used during Gog/Magog battle.
3/ Revelation 6:15 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;vsEzekiel 38:20 and all the men that are upon the face of the earth, shall shake at my presence, and the mountains shall be thrown down, and the steep places shall fall, and every wall shall fall to the ground.
Mountains shall be thrown down, all the men shall hide themselves in the rocks of mountains.
4/ Revelation 6:17 For the great day of his wrath is come; and who shall be able to stand?vsEzekiel 38:23 Thus will I magnify myself, and sanctify myself; and I will be known in the eyes of many nations, and they shall know that I am the LORD.
They shall realize it's God's wrath against them. Who shall be able to stand? And they shall know that Yahweh is the LORD. Yahweh shall reveal himself during the battle of Gog/Magog. This is also the great day of wrath from Yahweh when he makes himself known to the world. His wrath is toward Gog and his army.
