The returning Savior touches down upon the Mt of Olives causing a great earthquake (Zechariah 14:4)
Returning to the Mt of Olives is a direct fulfillment of Acts 1:11
Earthquake is a fulfillment of Nahum 1:5 and Isaiah 24:19-21
The final judgement of Revelation includes a great earthquake and 100 pound hailstones (Revelation 16:17-21)
This earthquake forms a valley running east to west from Jerusalem to the Mt of Olives as the Mt of Olives splits in two from north to south (Zechariah 14:4)
This valley allows the Jewish remnant to escape Jerusalem (Zechariah 14:5)
This is also the Valley of Decision spoken of by the prophet Joel where Christ will bring the nations to judge them (Joel 3:14)
This is the same as the judgement of the sheep and goats spoken of by Jesus in Matthew 25:31-33)
