A website has been released that provides detailed data on the probability of tsunamis hitting areas along the Nankai Trough within the next 30 years.
The Tsunami Hazard Station was newly established by the National Research Institute for Earth Science and Disaster Prevention, and released last month by the government's Earthquake Investigation Committee, which maps the probability that a region along the Nankai Trough will be hit by a tsunami within the next 30 years. Is shown in
The height of the tsunami is divided into more than 10 meters, more than 5 meters and more than 3 meters, and it is shown in purple, red, and yellow in order of the probability that these tsunamis come.
The probability of being hit by a tsunami of 3 meters or more, which is said to be causing houses to begin to be washed away or destroyed, is very high, "over 26%" in a wide area, mainly in Shikoku, Kinki, and Tokai. You can see the detailed probability of.
These probabilities do not include tsunamis caused by the largest magnitude 9.1 earthquake of unknown magnitude, but rather tsunamis that are considered more frequent.
The Disaster Prevention Research Institute of Science and Technology states, "Preparing for the largest class tsunami is important, but we want you to know the risks of tsunamis with a high probability of occurrence and use it as a material to verify how well you are preparing."
