Midori Ward Immediate evacuation warning Target Area, Floods, Inland Water, Landslide Hazard Map

Based on the lessons learned from Typhoon No. 18 in October 2014, Yokohama City extracted cliffs that may cause significant damage to houses in the event of a landslide. We have decided to issue "evacuation warning" with the announcement of "earth and sand disaster warning information".
There are two target areas in Midori Ward.
It is not safe in areas where the evacuation warning is not provided. In the event of a heavy rain or typhoon, pay attention to disaster prevention information and take evacuation actions as soon as possible at your own discretion.

　In order to ensure smooth and prompt evacuation in the event of a flood, information such as evacuation sites, etc. is displayed in the flood inundation area map showing the expected depth of water in the event of a flood.
If you are difficult to see on the scale of the hazard map, please also use the "Wai Wai Disaster Prevention Map" (outside site) (external site).

If Kanagawa Prefecture designates sediment-related disaster warning areas, etc. based on the "Law Concerning the Promotion of Sediment Disaster Prevention Measures in Sediment Disaster Warning Areas" (commonly known as the Sediment Disaster Prevention Law)", Yokohama City will create and publish hazard maps. going.
This hazard map shows areas where damage may occur if a landslide occurs due to torrential rainfalls during the rainy season or heavy rain associated with a typhoon. It was created so that citizens can take appropriate actions such as evacuation.
※As we can confirm about earth and sand disaster caution area from Yokohama citizen disaster prevention information "waiwai disaster prevention map (earth and sand disaster)" (outside site), we can confirm.
If you are difficult to see on the scale of the hazard map, please also use the "Wai Wai Disaster Prevention Map" (external site).
In addition, we distribute earth and sand disaster hazard map in each ward office.

※About confirmation of detailed position such as earth and sand disaster caution areas
Earth and sand disaster hazard map shows the approximate location of earth and sand disaster caution areas. The sediment-related disaster warning areas on the map surface are those at the time of creating the landslide hazard map, and may differ from the current designated situation. For legal drawings on earth and sand disaster warning areas, etc., please check the notification book of "Areas where there is a risk of earth and sand disaster" of Kanagawa earth and sand disaster information portal (outside site) or Yokohama Kawasaki flood control office of Kanagawa Please contact us.

　It is a map that summarizes various information such as the area where flooding is expected during heavy rain and the depth of flooding.
This map is used for smooth evacuation behavior against inundation and improvement of disaster prevention awareness during normal times.

Requests for Use

・Depending on the strength of the rain and how to descend, the flooded area and depth of inundation may differ from expectations.
・The inundation assumption of the inland water hazard map is created reflecting the maintenance status of rivers and sewers at the end of FY2018.
・The information side describes how to use the inundation hazard map and daily preparations. Please take a look at it.
