00:00The Nankai Earthquake, which the Meteorological Agency has begun to investigate whether the possibility of occurrence has increased, is expected to occur in the boundary of the plate called the Nankai Earthquake, which runs from the east coast to the west coast.
00:18The government estimates that if a super-massive earthquake of magnitude 9 occurs along the Nankai Trough, the death toll will exceed 320,000.
00:30This Nankai Earthquake has historically occurred repeatedly.
00:36If you write it down in the annual table, you can see that it has occurred at intervals of about 100 to 200 years.
00:44It has been more than 70 years since the Nankai Earthquake, which occurred around the end of the last war.
00:53As a result, the government's Earthquake Investigation Committee predicts that in the next 30 years along the Nankai Trough, the probability of a super-massive earthquake of magnitude 8 to 9 will occur at 70% to 80%.
01:10The recent super-massive earthquake around the end of the last war occurred on the west side about two years after it occurred on the east side.
01:19The previous super-massive earthquake occurred on the west side about 32 hours after it occurred on the east side.
01:28It is not always the case that a super-massive earthquake occurs from the east side to the west side in order.
01:36In addition, it is said that it occurred at once during the Edo period before that.
01:45This is a simulation CD of the Nankai Trough Earthquake created by the Cabinet.
01:51It is assumed that in Tokushima Prefecture and Wakayama Prefecture, the probability of magnitude 7 will be the maximum, and in Osaka Prefecture, the probability of magnitude 6 will be very strong.
02:06In addition, if it is the earliest in Wakayama Prefecture, the tsunami will arrive in two minutes from the earthquake.
02:13It is expected that the maximum tsunami height will be 20 meters in Wakayama Prefecture and 5 meters in Osaka Prefecture, and there is a possibility of causing serious damage.
02:25The Cabinet will evaluate whether the probability of a Nankai Trough Earthquake occurring has increased.
02:38And if the evaluation result or conclusion by an expert is not available after two hours, the evaluation process will be announced.
02:49As a result, if it is evaluated that the probability of a super-massive earthquake occurring has increased, it is possible that some people will be asked to evacuate for about a week depending on the decision of the local government.
