I believe it is literal, just as God destroyed that time of old which Hebrews 12 talks about, and also 2 Peter 3 talks about, and per many Scriptures in the Books of the OT prophets about the end of "the world that then was".
The Book of Revelation is not a symbolic Book. It's a Book laying bear literal Truths only using the figurative language of OT historical events as examples for the end of this world. And not all of Revelation uses the figurative speech of the OT. Quite a bit of it has direct literal statements, just as it is within all Books of The Bible.
