Last updated on March 14, 2025.
If Kanagawa Prefecture designates the landslide warning area, etc. in accordance with the Act on Promotion of Measures to Prevent landslide in the landslide warning Area, etc. (commonly known as the landslide Prevention Law), Yokohama City has created and published the hazard map.
The hazard map is an area that could cause damage in the event of landslide due to heavy rains caused by torrential rainfalls during the rainy season and typhoons, so that citizens can take appropriate actions such as evacuation when landslide is expected or landslide occurs.
