There is a new NBC 4-hour miniseries set to air during the May sweeps period (2-3 May) titled simply enough 10.5. No, this is not a sequel to 9 and ¿ weeks, nor is it a mini-sequel to 10. This number instead refers to a mega-earthquake that rocks the west coast of the United States. One may think that the network writers have done their homework and have consulted a geophysicist or two regarding the realism of their program, let alone the title. This is just a short note to comment on their potential folly. I would like to clarify to the network writers, as well as to the non-seismologists in the Earth science community what exactly a magnitude 10.5 earthquake could be, and why, if such were to occur, it may be more than just a west coast problem. Alternatively, NBC may just soon answer an age-old seismologic question...
