The Tokyo Metropolitan Government has reviewed its damage estimates, such as the earthquake directly beneath the Tokyo metropolitan area for the first time in 10 years, and clarified the damage expected mainly by the tsunami in the islands of Tokyo due to the huge Nankai Trough earthquake.
It is estimated that up to about 950 people will die.
The estimated damage was on 11 islands in the Izu Islands and Ogasawara Islands in Tokyo.
It is assumed that a tsunami with a maximum height of 28 meters in about 14 minutes and a maximum height of 27 meters in about 17 minutes will flood Niijima and Kozushima after an earthquake of magnitude 9 class Nankai Trough caused an earthquake on Shikinejima. increase.
The height of the tsunami on other islands is said to reach up to 7 to 17 meters.
It is estimated that up to 1260 buildings will be completely destroyed mainly by the tsunami, and up to about 950 people will die if it occurs in the early morning of winter.
The death toll is reduced to nearly half of the previous 10-year-old assumption.
This is because the city is becoming more aware of evacuation based on the results of questionnaire surveys of residents.
In addition, if the route becomes unavailable and the fuel supply from outside the island is cut off, the diesel power plant may stop and a power outage may occur, or cars and buses may not be available for a long period of time.
It is also assumed that the submarine communication cable may be disconnected and communication may be interrupted.
