Disasters in Yokohama City (Past Disaster History)

Last updated on April 9, 2025.

Every year, the Yokohama City Crisis Management Office compiles records of earthquakes and storms and floods that occurred in the city in a booklet called "Disasters in Yokohama City".
Each disaster includes the status of emergency response activities in damage situation and the weather condition, which can be used for disaster countermeasures in each region.
On this homepage, we can download PDF file of "disaster of Yokohama-shi" after 2000.

In addition, we make "disaster of Yokohama-shi" from 1975 and, about booklet version, can read in city hall the third floor citizen information center.

You can search for characters from each PDF file.
