Isaiah 17:1 Damascus will cease to be a city, she will be reduced to a heap of ruins forever desolate. Animals will live there, undisturbed.
Jeremiah 49:23-27 Of Damascus: The Syrians are covered in confusion, for they have heard news of a coming disaster, they run around in fear and trembling and panic grips them. No more joyful songs or celebrations are heard in her streets, because on that Day her young men will fall and soldiers will lie still in death. The Lord says; I will kindle a fire inside Damascus and it will devour her strongholds.
Amos 1:3-4 For crime after crime of Damascus, I will give them no reprieve because they oppressed My Land with malicious spite. Therefore I will send fire to consume her strongholds.
Zechariah 9:1-2 The Word of the Lord comes to the lands north of Israel and it will soon come upon Damascus. For to the Lord belongs all of that area and even though the cities of Lebanon have become rich, He will strip them of all their possessions and break their power. A devastating fire will devour them all.

All these prophecies tell of the soon to happen destruction of Damascus, Syria.
Note that in all cases, they go on to talk of other nations who are also affected by this fire judgement. Isaiah 66:16 In particular Isaiah 17:4-6 says how Jacob, that is: the 10 tribes of Israel- now the Western nations and the 2 tribes of Judah now the current State of Israel, will lose their strength. It seems that most of the world’s military forces will be destroyed. Isaiah 34:2-3, Hosea 2:18, Micah 5:10-11
Although the Sixth Seal, the next prophesied event to happen according to the sequence in Revelation, does not mention fire as the means of punishment, [there is nothing in Revelation 6:12-17 to say how it will be carried out] we can ascertain the details from parallel passages like: Isaiah 34:2-4, Isaiah 2:12-21, Joel 2:1-11, Malachi 4:1 and especially 2 Peter 3:7 & 10.
Notice in Jeremiah 49:23, how everyone knows what is coming. This can be explained by the 24 hour period between the initial flash of a Coronal Mass Ejection sunstrike and the arrival of the main mass of superheated plasma. Ezekiel 7:10-19
That it will be a single Day of destruction is confirmed by the use in every case of the Hebrew and Greek words for a 24 hour period and this fits how a CME will hit the earth and then continue on into outer space. Isaiah 63:4, Joel 1:15
