Zechariah  14:4 predicts, “On that day his feet will stand on the Mount of Olives, east  of Jerusalem, and the Mount of Olives will be split in two from east to west,  forming a great valley, with half of the Mount shall move north and half moving  south.” “That day” is a reference to the Day of  the Lord, and the One who stands on the mountain is the Lord Himself. So,  yes, this passage predicts the second coming of Christ.

The opening of  Zechariah 14 speaks of a future day when Jerusalem will be plundered by its  enemies. Verse 2 prophesies that all nations will gather against Jerusalem and  capture and ransack the city. Half of the citizens of Jerusalem will flee the  devastation, but the other half will remain. This will be one half of the one  third of the Jewish population still alive in Jerusalem after the Tribulation  (13:8). Then, Zechariah says, the Lord Himself will go forth and engage these  opponents in battle (14:3). Verse 4 speaks of the Messiah standing on the Mount  of Olives, a hill near Jerusalem on the east. The mountain will split, creating  an enormous valley. Since none of this has taken place yet, the prophecy points  to a future time.

A parallel passage tells of the Battle  of Armageddon (Revelation 19:11-21). Revelation 16:18-21 predicts horrible events at the end  of the Tribulation when the seventh bowl is poured out:

“Then there came  flashes of lightning, rumblings, peals of thunder and a severe earthquake. No  earthquake like it has ever occurred since man has been on earth, so tremendous  was the quake. The great city split into three parts, and the cities of the  nations collapsed. . . . Every island fled away and the mountains could not be  found. From the sky huge hailstones of about a hundred pounds each fell upon  men. And they cursed God on account of the plague of hail, because the plague  was so terrible.”

The earthquake in Revelation could very well speak of  the event described in Zechariah when the Mount of Olives splits in two. Jesus  the Messiah will cause an earthquake at His second coming that will serve as  part of the destruction of God’s enemies. The outcome of this battle is never in  doubt: Christ will be the victor, Israel’s enemies will be destroyed, and the  beast (Antichrist) and false prophet will be thrown into the lake of fire (Revelation 19:11-21).
