Good program with interesting information but nothing not already known and with some limitations in research perhaps. Additionally, where can the film of the underwater exploration of the location of the tectonic plate movement i.e., mega thrust result, be seen? There was a tantalizing few minutes of an underwater rover coming up to the "cliffs" formed from the mega thrust earthquake but nothing that could been properly - frustrating! There was also an account of the 1607 surge which moved up the Bristol Channel and inundated land and took lives. Another account of this event considers an underwater landslide off Ireland, as the cause and not a formerly, inactive plate movement. Santorini volcano and parting of the Reed Sea was more up to date although nothing mentioned about the Krakatoa eruption which caused a gigantic tsunami. The Toba volcano was not mentioned either and this was responsible for a large tsunami.
