Most seismologists of our country predicted that next Nankai earthquake will occur around 2040±10year. Tou-Nankai and Nankai Earthquake are twin earthquake because the twin occurred eight times after 684 AD. and in the worst case, it simultaneously broke. If they occur at the same time, damage will be huge. Gigantic tsunamis as well as strong ground motion will hit every coastal city and town located between the Izu peninsula and Shikoku island facing the Pacific. Especially, in Osaka, highly densely populated lowland areas with underground urban facilities such as subway network and shopping mall, the damage may be unbelievable huge. Knowing hazard, knowing vulnerability and knowing scenario are very urgent to reduce damage.
