As I've mentioned before this blog will introduce you to other interesting websites that offer a similar theme.
Apocalypse Fiction Magazine is an excellent resource for short works of fiction, editorial, comics, series and novels in the Apocalyptic genre.
The Strange Horizons website is another site that educates curious readers. Featuring reviews of apocalyptic works, columns, articles, poetry, and an art gallery, Strange Horizons is based around Christian Apocalyptic Fiction (as most good apocalypse literature should be).
Check these two sites out and don't forget to look up http://www.the-judas-syndrome.com to check out upcoming new movies and literature in the apocalyptic genre, and for news about it's release.
