川口市ハザードマップ

Kawaguchi City Hazard Map displays evacuation site information such as Arakawa flood inundation assumption, easiness of shaking, building damage risk and evacuation shelter, wide area / primary evacuation site, and temporary evacuation plaza in Kawaguchi City, Saitama Prefecture.

"Kawaguchi City Hazard Map" is the Arakawa flood inundation assumption, easiness of shaking (estimated seismic intensity), building damage risk and evacuation center (designated / welfare), evacuation site (designated emergency evacuation / wide area) in "Kawaguchi City, Saitama Prefecture".・ It is an application that displays evacuation site information such as primary).

In conjunction with GPS information, the disaster prevention information of the current position is combined and displayed with the live-action video taken by the camera.

Arakawa flood inundation

"Arakawa Flood Inundation" posted on the app is based on the assumption that the Arakawa River embankment will collapse due to the largest rainfall assuming a total rainfall of 632 mm for 72 hours. Kawaguchi City provides information based on the "Arakawa River Inundation Area Map" published by the river office, which simulates the inundation situation.

* The flood assumption is just a guide. In reality, depending on how it rains, the shape of the land, the conditions of roads and sewers, etc., it may not always be flooded as expected on the hazard map. In addition, there is a possibility of flooding even in places not designated as the assumed area, so please evacuate as soon as possible depending on the local conditions in the event of heavy rain.

Ease of shaking

Various earthquakes are expected at the National Central Disaster Prevention Council and Saitama Prefecture, but if a magnitude 7 class earthquake occurs near Tokyo Bay, it is expected that a maximum seismic intensity of 6 or higher will occur in Kawaguchi City as well. This easiness of shaking map is created based on the earthquake that is expected to cause the largest shaking in Kawaguchi City (earthquake directly under the capital). (Earthquake scale: Moment magnitude 7.3)

The damage to the area on the south side is increasing as a whole due to the assumption based on the earthquake that occurs from the epicenter on the south side of Kawaguchi City and the spread of the Arakawa lowland where the ground is weak.

Building damage risk

Based on the easiness of shaking of an earthquake, it is possible to study the damage caused by combining the social data of the area such as the structure of the building and the year of construction.

This map is based on the "easiness of shaking of the ground" map, which predicts the ease of shaking (seismic intensity) in the event of an earthquake directly beneath the capital, which is expected to cause great damage to Kawaguchi City. "Building damage risk" that shows the relative risk by calculating the rate of total destruction of buildings according to the seismic intensity of each mesh from the current state of buildings by different and year of construction, and dividing the results into 7 ranks. It is displayed as.

* Ratio of total number of buildings destroyed: Ratio of total number of buildings destroyed to the number of buildings in the mesh (excluding partial damage and partial destruction)

Evacuation site in the event of a storm or flood, evacuation site in the event of an earthquake

Wide area evacuation site (at the time of the earthquake)

It is a place to evacuate when a fire spreads and the entire area becomes dangerous in the event of a disaster.

Evacuate when the primary evacuation site, the evacuation plaza, becomes dangerous.

It is not a place to live in an evacuation center like a shelter.

Primary evacuation site (at the time of the earthquake)

Although it is not as large as a wide area evacuation site, it is a place where you can secure a considerable degree of physical and life safety.

Evacuate when the evacuation square becomes dangerous.

Temporary evacuation square

It is a place where you can evacuate for the time being after a disaster occurs and try to keep yourself safe while watching the transition of the disaster. Parks and elementary, junior high, and high schools excluding wide-area evacuation sites and primary evacuation sites are designated (334 locations as of March 3rd year of Reiwa).

Please check the city homepage for location details.

Designated shelter (in the event of an earthquake or storm or flood)

This facility was established to protect people who have difficulty living at home due to damage to their homes due to the earthquake or flood, and to secure living functions such as accommodation and meals. It is a place to evacuate when a fire spreads and the entire area becomes dangerous in the event of a disaster. Please be aware of the status of evacuation shelters from the city, as it may not be possible to open the facility depending on the damage situation. When evacuating, please bring your own necessary items such as food, drinking water, indoor shoes and blankets as much as possible.

Welfare shelter (at the time of the earthquake)

Receiving facilities for people who require special consideration (people who need constant assistance in eating, excreting, and moving, etc., who have difficulty living together in the evacuation center), which significantly hinders the life of the evacuation center in general evacuation centers. is.

* Since the welfare evacuation center is a secondary evacuation center, it is not an evacuation center that was established from the beginning of the disaster.

Designated emergency shelter (in case of wind and flood damage)

It will be a temporary emergency evacuation site as a place to protect lives from flooding of rivers and torrential rains. Designated emergency evacuation sites are designated for each type of disaster. When evacuating, please bring your own necessary items such as food, drinking water, indoor shoes and blankets.

Before using

"Kawaguchi City Hazard Map" (hereinafter referred to as "this application") is an application that displays damage estimation information and evacuation site information in order to learn about disaster prevention and disasters in advance. When using in the event of a disaster, please understand that the map will not be displayed due to the interruption of the communication line and that the displayed contents of the application are assumed information, and after confirming the actual damage situation, evacuation information of the government and information Please evacuate based on your own judgment.

Due to the specifications of the app, the disaster prevention information posted may not be the latest. Please refer to the disaster prevention information announced by the government in a timely manner.

This application sends the user's location information to display the current location. Location information will be sent only when the "GPS automatic tracking" function is turned on in this application.
