Revelation 11:13,14

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.

At the time of the two prophets ascension to heaven, a great earthquake hits Jerusalem. This great earthquake opens a great rift valley that allows the faithful remnant of Israel to escape by the valley to the area of Petra in Jordan where they will be protected by God's angels for 3 ½ years. Seven thousand are killed by this earthquake but the rest of the remnant in Jerusalem give glory to God for proving that He is the God of Israel and the God of heaven.

The remnant giving glory to the God of heaven are probably the ones that had been following the teaching of these two prophets but they might not have totally bought into the message until they rose from the dead. This remnant will probably be among those that flee to the mountains of Jordan for protection.

After the God of heaven raises these two prophets from the dead, the problem that remains is that most on earth will still be deceived into thinking that there is a God dwelling on the earth. All those that want this  lawless man  to be God more than the real God of heaven will follow him. They will turn against all world religion that claims God is in heaven and they will burn all such religious institutions with fire. This is all further explained in chapter seventeen.
