It is not... about one's point of view. It is about what God's Word says as written. Your claim is that there will be THREE major earthquakes at the end, when there will only be TWO. What is confusing you is that you have failed to understand that the 6th Seal description in Revelation 6 has TWO PARTS like I said, while you are wrongly including all the 6th Seal events as the day Jesus returns.
The following is NOT about Jesus' return. It is about the Revelation 12:7 war in Heaven event that will cast Satan and his angels out of heaven down to this earth in plain sight to begin the time of "great tribulation", i.e. the idea of "... the stars of heaven fell unto earth, even as a fig tree casteth her untimely figs," is PRIOR to Christ's coming.
Rev 6:12-13
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.
KJV
Thus the first earthquake happens when Satan and his angels are cast out of Heaven at the END of this world like "untimely figs". That event most of the whole world will be deceived about, which is why even many brethren in Christ miss this 6th Seal having TWO PARTS. It's about the coming of a false-Messiah that will fool the whole world, which will be Satan ("dragon" of Rev.13:4) himself playing Jesus Christ in Jerusalem for the trib.
From Revelation 6:14-17 is all about the events of Jesus' coming, which is the 2nd PART of that 6th Seal. And thus the great earthquake of Revelation 11 on the 7th Trumpet is actually the one implied in the 6th Seal. However, notice it is mentioned in that 1st PART of the 6th Seal before the "untimely figs" event. Why would that be? Because Satan coming as the false-Messiah wants to be worshiped in place of Christ, which happens first at the end, to mimic Christ's coming.
The Revelation 11 Scripture below reveals ONE earthquake between the "two witnesses" ascending and Jesus' coming, but the 2nd Woe is actually ended by that "great earthquake". All that, the ascension of the "two witnesses", the "great earthquake", and Jesus' coming all occur within that "same hour". So why would the Rev.6:12-13 show an earthquake happening when the "untimely figs" fall to earth, which is prior to the trib? It's because it is to IMPLY Christ's coming when it will instead be the coming of the false-Messiah. Thus there are TWO earthquakes to occur, the first one is IMPLIED by the 1st Part of the 6th Seal, and the second one in Rev.11 in the same hour of Jesus' coming.
Rev 11:12-15
12 And they heard a great voice from heaven saying unto them, Come up hither. And they ascended up to heaven in a cloud; and their enemies beheld them.
13 And the same hour was there a great earthquake, and the tenth part of the city fell, and in the earthquake were slain of men seven thousand: and the remnant were affrighted, and gave glory to the God of heaven.
14 The second woe is past; and, behold, the third woe cometh quickly.
15 And the seventh angel sounded; and there were great voices in heaven, saying, "The kingdoms of this world are become the kingdoms of our Lord, and of His Christ; and He shall reign for ever and ever."
