Um I guess I could give my own opinion of Revelation interpretations tied in with logic.
6 I watched as the Lamb opened the first of the seven seals. Then I heard one of the four living creatures say in a voice like thunder, “Come!” 2 I looked, and there before me was a white horse! Its rider held a bow, and he was given a crown, and he rode out as a conqueror bent on conquest.
A major military campaign led by a ruler hungry for the land around him. WWII-similar situation when national socialist Germany was invading nearby countries.
3 When the Lamb opened the second seal, I heard the second living creature say, “Come!” 4 Then another horse came out, a fiery red one. Its rider was given power to take peace from the earth and to make people kill each other. To him was given a large sword.
Some sort of political leader or warlord, perhaps even opposition or allied support to the above.
5 When the Lamb opened the third seal, I heard the third living creature say, “Come!” I looked, and there before me was a black horse! Its rider was holding a pair of scales in his hand. 6 Then I heard what sounded like a voice among the four living creatures, saying, “Two pounds of wheat for a day’s wages, and six pounds of barley for a day’s wages, and do not damage the oil and the wine!”
Implying money or currency issues making trade a problem. Economic issues.
7 When the Lamb opened the fourth seal, I heard the voice of the fourth living creature say, “Come!” 8 I looked, and there before me was a pale horse! Its rider was named Death, and Hades was following close behind him. They were given power over a fourth of the earth to kill by sword, famine and plague, and by the wild beasts of the earth.
Increase in warfare, famine, and disease. Not sure what "wild beasts" implies unless animals are contracting a disease that can be passed to people.
9 When he opened the fifth seal, I saw under the altar the souls of those who had been slain because of the word of God and the testimony they had maintained. 10 They called out in a loud voice, “How long, Sovereign Lord, holy and true, until you judge the inhabitants of the earth and avenge our blood?” 11 Then each of them was given a white robe, and they were told to wait a little longer, until the full number of their fellow servants, their brothers and sisters, were killed just as they had been.
Increase in crime rates and murder.
12 I watched as he opened the sixth seal. There was a great earthquake. The sun turned black like sackcloth made of goat hair, the whole moon turned blood red, 13 and the stars in the sky fell to earth, as figs drop from a fig tree when shaken by a strong wind. 14 The heavens receded like a scroll being rolled up, and every mountain and island was removed from its place.
A massive earthquake larger than has ever been measured.The sun either dies out or is blocked from the Earth. With the absence of the sun and the majority of its light, the moon would turn red just as in a lunar eclipse.A bombardment of meteorites from space.Degrading of the atmosphere causing it to thin out. This would cause colder temperatures and more hostile conditions from radiation.Mountains collapsing from major earth movement? Islands disappearing under the ocean from rising water levels?15 Then the kings of the earth, the princes, the generals, the rich, the mighty, and everyone else, both slave and free, hid in caves and among the rocks of the mountains. 16 They called to the mountains and the rocks, “Fall on us and hide us from the face of him who sits on the throne and from the wrath of the Lamb! 17 For the great day of their wrath has come, and who can withstand it?”
Anyone who isn't dead yet will be forced to retreat to subterranean levels to evade the hostile conditions of Earth and the many disasters.
