From a loss-of-life standpoint, the Japanese earthquake/tsunami may well be at least five times more severe than 9/11. While natural disasters in the past have claimed more lives, itâs extremely rare for a developed country to suffer this kind of catastrophe.apan, being an advanced country, is expected to have a large amount of property loss and (relative to the size of the earthquake and tsunamis) small human casualties. Nevertheless, because the quake and tsunami are the largest to strike Japan in at least 150 years, both numbers will be large.
