First the trumpet will sound and the dead will rise from their graves to be judged. The living Christians will then also go up and meet Jesus in the air. Next time He comes to earth He will stand on the Mount of Olives, Zechariah 14:4.

"Zechariah 14:8 And it shall be in that day, that living waters shall go out from Jerusalem; half of them towards the former sea, (Mediterranean) and half of them towards the hinder sea: (Dead Sea) in summer and in winter shall it be.
Now we can see quiet easily what is going to happen, the Messiah 'Yeshua' on His return, will plant His feet on the Mount of Olives, and there will be an earthquake, it will cause the Mount of Olive’s to split even up to the Temple Mount. With the Mount of Olive’s split water will be able to easily run to the Dead Sea, as it already runs to the Dead Sea through the Kidron Valley. This can be seen at the Greek Monastery of Mar Saba near Bet Sahur. With this water running from the Temple Mount it would have no problem finding its way to the Soreq River that runs near Bet Shemesh and into the Mediterranean Sea.
We find more Scripture on this subject in Ezekiel 47:1-12. Verse :1 says the water will come out from under the house. In reference to the Temple Mount or the House of God. Verse:8 Then said he unto me, These waters issue out toward the east country, and go down into the desert, and go into the sea; which being brought forth into the sea, the waters shall be healed. (The dead waters of the Dead Sea will be healed)."
If apparitions of Jesus are reported, do not believe those people. I can't find the verse, but it's something like "Look, there's Jesus over there."
