Anatomy of an Earthquake examines what would happen if the 'Big One' were to strike North America, something scientists predict will happen soon. Through riveting stories from eyewitnesses, Anatomy of an Earthquake relives the infamous 1994 California earthquake that released more than five megatons of explosive force in the Los Angeles region. It explores the latest technology and structural testing that will hopefully prepare citizens for the next "big one". This fascinating documentary uses science and CGI (Computer Generated Imagery) to uncover the likely impact on Los Angeles if a major earthquake occurs.
