A wonderfully well-written and successful plotline, covering what will occur to the general population in the unexpected event of a 10.5 magnitude earthquake. As well as the breakdown of society as people have since come to know it.
Also the disbelief of those in authority to what seems to be far-fetched; previously unknown Faultlines in the USA. This Movie also shows the lengths to which Authority figures will go to, in a vain attempt to hide the truth.
