“The Japanese government estimates that a major earthquake on the Nankai Trough would cause 169.5 trillion yen in direct damage and 50.8 trillion yen in economic losses for the following year. A study by the Japan Society of Civil Engineers in 2018 estimated that the long-term damage from the earthquake could result in 1,240 trillion yen in economic losses over a 20-year period.[11] It is predicted that the economic damage is likely to be 10 times higher than for the 2011 Tōhoku earthquake and tsunami.[12] A death toll as high as 230,000 has been suggested for such an event.[13]”
