“Jericho” isn’t just coming back to CBS for its new second season Tuesday, Feb. 12 at 10 p.m. It’s also bowing on Sci Fi Channel the previous night, Feb. 11, with a four-episode first-season marathon 7-11 p.m.

That’s on top of the current encores on Universal HD. (Upcoming UHD episodes: “Walls of Jericho” Friday at 6 and 10 p.m. and 2 a.m.; “Four Horsemen” Saturday at 1 p.m., Sunday at 9 a.m., Monday at 6 and 10 p.m. and 2 a.m.).

Sci Fi’s pickup of first- and second-season repeats also includes HD airings on the channel’s new high-definition simulcast feed. Too bad it’s not yet widely available. (It does get carried on DirecTV.) "Jericho" episodes will encore on Sci Fi Mondays at 10 p.m. starting Feb. 18.

You can also wallow in nuclear nightmares at CBS’ busy “Jericho” web site, which offers Season 2 sneak peeks alongside episode guides, behind-the-scenes footage, insiders’ commentary and full-episode streams of that cult-creating 22-hour first season.
