The results of the ninth report were published in September 2022. In the assessment, 3 types of vulnera-bilities are measured: structural vulnerability, fire vulnerability, and general vulnerability; and on a scale of 1 to 5, each of Tokyo's small community units is evaluated.　 The overall danger level is assessed based on the difficulty factor of carrying out activities following an earthquake.　Tokyo Liquefaction Hazard Map　The liquefaction prediction map created in 1986 has been updated for the first time in 9 years since 2012, and we developed a program to automatically assess liquefaction risk based on this map in 2021. The revised 2023 version is now available on our website.https://doboku.metro.tokyo.lg.jp/start/03-jyouhou/ekijyouka/top.aspx　The Tokyo Liquefaction Hazard Map was a guide created with the aim of indicating the probability of the occurrence of ground liquefaction and it is different from those that estimated the damage caused by specific earthquakes.9
