John’s Revelation – 18“And there were noises and thundering and lightnings; and there was a great earthquake, such a mighty and great earthquake as had not occurred since men were on the earth.” (Revelation 16)

Josephus - “for there broke out a prodigious storm in the night, with the utmost violence, and very strong winds, with the largest showers of rain, with continued lightnings, terrible thunderings, and amazing concussions and bellowings of the earth, that was in an earthquake. These things were a manifest indication that some destruction was coming upon men, when the system of the world was put into this disorder; and any one would guess that these wonders foreshowed some grand calamities that were coming” (The Wars of The Jews, 4:4:5)
John’s Revelation – 19“Now the great city was divided into three parts, and the cities of the nations fell. And great Babylon was remembered before God, to give her the cup of the wine of the fierceness of His wrath.” (Revelation 16)
Josephus – “it so happened that the sedition at Jerusalem was revived, and parted into three factions, and that one faction fought against the other; which partition in such evil cases may be said to be a good thing, and the effect of divine justice.” (The Wars of The Jews, 5:1:1)

John’s Revelation –21 “And great hail from heaven fell upon men, each hailstone about the weight of a talent.” (Revelation 16)
Josephus – “Now the stones that were cast were of the weight of a talent, and were carried two furlongs and further. The blow they gave was no way to be sustained, not only by those that stood first in the way, but by those that were beyond them for a great space. As for the Jews, they at first watched the coming of the stone, for it was of a white color, and could therefore not only be perceived by the great noise it made, but could be seen also before it came by its brightness;” (The Wars of The Jews, 5:6:3)
John’s Revelation – 5When 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. 6Then I heard what sounded like a voice among the four living creatures, saying, “A quart of wheat for a day’s wages, and three quarts of barley for a day’s wages, and do not damage the oil and the wine!” (Revelation 6)

Josephus – Many there were indeed who sold what they had for one measure; it was of wheat, if they were of the richer sort; but of barley, if they were poorer. When these had so done, they shut themselves up in the inmost rooms of their houses, and ate the corn they had gotten; some did it without grinding it, by reason of the extremity of the want they were in, and others baked bread of it, according as necessity and fear dictated to them: a table was no where laid for a distinct meal, but they snatched the bread out of the fire, half-baked, and ate it very hastily. (The Wars of The Jews, 5:10:2)

John’s Revelation – 8The second angel sounded his trumpet, and something like a huge mountain, all ablaze, was thrown into the sea. A third of the sea turned into blood, 9a third of the living creatures in the sea died, and a third of the ships were destroyed. (Revelation 8)

Josephus – And for such as were drowning in the sea, if they lifted their heads up above the water, they were either killed by darts, or caught by the vessels; but if, in the desperate case they were in, they attempted to swim to their enemies, the Romans cut off either their heads or their hands; and indeed they were destroyed after various manners everywhere, till the rest being put to flight, were forced to get upon the land, while the vessels encompassed them about (on the sea): but as many of these were repulsed when they were getting ashore, they were killed by the darts upon the lake; and the Romans leaped out of their vessels, and destroyed a great many more upon the land: one might then see the lake all bloody, and full of dead bodies, for not one of them escaped.
And a terrible stink, and a very sad sight there was on the following days over that country; for as for the shores, they were full of shipwrecks, and of dead bodies all swelled; and as the dead bodies were inflamed by the sun, and putrefied, they corrupted the air, insomuch that the misery was not only the object of commiseration to the Jews, but to those that hated them, and had been the authors of that misery. This was the upshot of the sea-fight. The number of the slain, including those that were killed in the city before, was six thousand and five hundred. (The Wars of The Jews, 3:10:9.)

And from Matthew 24:

1) 7Nation will rise against nation, and kingdom against kingdom. There will be famines and earthquakes in various places.

And indeed what greater mischief can the war, though it should be a violent one, do to us than the earthquake hath done? Nay, there is a signal of our enemies’ destruction visible, and that a very great one also; and this is not a natural one, nor derived from the hand of foreigners neither, but it is this, that they have barbarously murdered our ambassadors, contrary to the common law of mankind; and they have destroyed so many, as if they esteemed them sacrifices for God, in relation to this war. But they will not avoid his great eye, nor his invincible right hand; and we shall be revenged of them presently, in case we still retain any of the courage of our forefathers, and rise up boldly to punish these covenant-breakers. (The Wars of The Jews, 1:19:4).

2) 15So when you see standing in the holy place ‘the abomination that causes desolation,’ spoken of through the prophet Daniel—let the reader understand – 16then let those who are in Judea flee to the mountains.

“And now, when the multitude were gotten together to an assembly, and everyone was in indignation at these men’s seizing upon the sanctuary, at their rapine and murders but had not yet begun their attacks upon them Agnus stood in the midst of them, and casting his eyes frequently at the temple, and having a flood of tears in his eyes he said, ‘Certainly, it had been good for me to die before I had seen the house of God full of so many abominations, or these sacred places that ought not to be trodden upon at random, filled with the feet of these bloodshedding villains’” (The Wars of The Jews, 4:3:10).

3) 21For then there will be great distress, unequaled from the beginning of the world until now – and never to be equaled again.
Now this vast multitude is indeed collected out of remote places, but the entire nation was now shut up by fate as in prison, and the Roman army encompassed the city when it was crowded with inhabitants. Accordingly, the multitude of those that therein perished exceeded all the destructions that either men or God ever brought upon the world. (The Wars of The Jews, 6:9:4)

4) 24For false Christ’s and false prophets will appear and perform great signs and miracles to deceive even the elect – if that were possible.

A false prophet was the occasion of these people’s destruction, who had made a public proclamation in the city that very day, that God commanded them to get upon the temple, and that there they should receive miraculous signs of their deliverance. Now there was then a great number of false prophets suborned by the tyrants to impose on the people, who denounced this to them, that they should wait for deliverance from God; and this was in order to keep them from deserting, and that they might be buoyed up above fear and care by such hopes.
Now a man that is in adversity does easily comply with such promises; for when such a seducer makes him believe that he shall be delivered from those miseries which oppress him, then it is that the patient is full of hopes of such his deliverance. (The Wars of The Jews, 6:5:2)

5) 29. . . the stars will fall from the sky, and the heavenly bodies will be shaken.

Thus were the miserable people persuaded by these deceivers, and such as belied God himself; while they did not attend nor give credit to the signs that were so evident, and did so plainly foretell their future desolation, but, like men infatuated, without either eyes to see or minds to consider, did not regard the denunciations that God made to them. Thus there was a star resembling a sword, which stood over the city, and a comet, that continued a whole year.
Thus also before the Jews’ rebellion, and before those commotions which preceded the war, when the people were come in great crowds to the feast of unleavened bread, on the eighth day of the month Xanthicus, and at the ninth hour of the night, so great a light shone round the altar and the holy house, that it appeared to be bright day time; which lasted for half an hour. (The Wars of The Jews, 6:5:3)

6) 30“At that time the sign of the Son of Man will appear in the sky, and all the nations of the earth will mourn. They will see the Son of Man coming on the clouds of the sky, with power and great glory.”

Besides these, a few days after that feast, on the one and twentieth day of the month Artemisius, a certain prodigious and incredible phenomenon appeared: I suppose the account of it would seem to be a fable, were it not related by those that saw it, and were not the events that followed it of so considerable a nature as to deserve such signals; for, before sun-setting, chariots and troops of soldiers in their armor were seen running about among the clouds, and surrounding of cities. Moreover, at that feast which we call Pentecost, as the priests were going by night into the inner (court of the temple,) as their custom was, to perform their sacred ministrations, they said that, in the first place, they felt a quaking, and heard a great noise, and after that they heard a sound as of a great multitude, saying, “Let us remove hence.” (The Wars of The Jews, 6:5:3)

7) 16then let those who are in Judea flee to the mountains. 17Let no one on the roof of his house go down to take anything out of the house. 18Let no one in the field go back to get his cloak.

And that is exactly what his followers did. Thus, the early Christians fled to the hills and were saved, while the Jews rush to the Temple and were destroyed – and this happened to that same generation Jesus spoke to before his death. This is the way an early Roman historian recorded it:
While the holy house was on fire, everything was plundered that came to hand, and ten thousand of those that were caught were slain; nor was there a commiseration of any age, or any reverence of gravity; but children, and old men, and profane persons, and priests, were all slain in the same manner; so that this war went round all sorts of men, and brought them to destruction, and as well those that made supplication for their lives, as those that defended themselves by fighting. The flame was also carried a long way, and made an echo, together with the groans of those that were slain ; and because this hill was high , and the works at the temple were very great, one would have thought that the whole city had been on fire. Nor can one imagine anything either greater or more terrible than this noise; for there was at once a shout of the Roman legions, who were marching all together, and a sad clamour of the seditious, who were now surrounded with fire and sword.
The people also that were left above were beaten back upon the enemy, and under a great consternation, and made sad moans at the calamity they were under; the multitude also that was in the city joined in this outcry with those that were upon the hill; and besides many of those that were worn away by the famine, and their mouths almost closed when they saw the fire of the holy house, they exerted their utmost strength, and brake out into groans and outcries again: Perea did also return the echo, as well as the mountains round about,[the city,] and augmented the force of the entire noise.
Yet was the misery itself more terrible than this disorder; for one would have thought that the hill itself, on which the temple stood, was seething-hot , as full of fire on every part of it, that the blood was larger in quantity than the fire, and those that were slain more in number that those that slew them; for the ground did nowhere appear visible, for the dead bodies that lay on it; but the soldiers went over the heaps of these bodies, as they ran upon such as fled from them. (The Wars of The Jews, 6:5:1)

This is a partial list from my own study - the work of Josephus is very long and I have not read it all. But this gives you an idea of the total destruction of Jerusalem as foretold by Jesus.
