The East Valley Tribune published an extensive set of news features on earth fissures in their Sunday edition, including timeline, maps, videos, and an animation of how fissures form.
KPHO, CBS channel 5 in Phoenix, also has a nice video segment with great aerial shots of the 2005 fissure in Chandler Heights that triggered the recent interest in this hazard.
