Zechariah 14:3-5

But then GOD will march out against the godless nations and fight—a great war! That’s the Day he’ll take his stand on the Mount of Olives, facing Jerusalem from the east. The Mount of Olives will be split right down the middle, from east to west, leaving a wide valley. Half the mountain will shift north, the other half south. Then you will run for your lives down the valley, your escape route that will take you all the way to Azal. You’ll run for your lives, just as you ran on the day of the great earthquake in the days of Uzziah, king of Judah. Then my GOD will arrive and all the holy angels with him.
