National Seismic Hazard Map 2018 Edition

Expansion of areas with seismic intensity of 6 weak or higher within 30 years! Announcement of the 2018 National Earthquake Motion Prediction Map!

The document is the 2018 edition of the "National Seismic Motion Prediction Map," which shows the probability of experiencing a major earthquake with a seismic intensity of 6 weak or higher within the next 30 years, as assessed by the government's Earthquake Research Committee. At the end of 2017, the probability of a massive earthquake occurring in the Kuril Trench off the Pacific coast was reassessed, resulting in a significant increase in the likelihood of a major earthquake in the southeastern part of Hokkaido.

In Japan, there are still areas where active fault surveys have not been sufficiently conducted, and there may be unknown active faults. Just because the probability is low does not mean we can let our guard down. The "α Damper Ex II" protects your important family and home from earthquakes, providing a safe and secure living environment. [Excerpt of the content] - In prefectural capitals, Chiba City has a probability of 85%, Yokohama 82%, and Mito City 81%, which are high probabilities. - In areas affected by the Nankai Trough earthquake, Kochi City has a probability of 75%, Shizuoka City 70%, Tsu City 64%, and Tokushima City 73%. - In the three major metropolitan areas, Tokyo has a probability of 48%, Nagoya City 46%, and Osaka City 56%. *For more details, please refer to the PDF document or feel free to contact us.
