Preparing for heavy rains and typhoons
Last update date September 1, 2020
１．Preparing for everyday life-preparation
Let's check the familiar situation on the hazard map!
・Let's check if there is no cliff near your home (earth and sand disaster hazard map)
・Make sure that there is no risk of flooding near your home. (Inundation Hazard Map)
・Let's check the evacuation route from your home to the evacuation center on the map.
[Be careful when thinking about evacuation routes]
・Check multiple evacuation routes so that you can evacuate to two or more evacuation centers.
・Avoid roads that may be closed due to flooding due to heavy rain or landslides.
Let's check the items to be taken out during evacuation!
・Prepare items to be taken out during evacuation on a daily basis so that you can take them out immediately.
・The items to be taken out should be kept to a minimum. (Radio, drinking water, flashlights, pharmaceuticals, baby products, etc.)
Let's work together to protect our town!
・In the event of an emergency, cherish your relationship with your neighbors on a daily basis so that you can help each other.
・Let's create a system that can cooperate in the community to protect the safety of people who have difficulty responding flexibly, such as evacuation behavior in the event of a disaster due to disability or elderly people.
・Let's talk about the cooperation system in the event of a disaster for nearby social welfare facilities in the area on a daily basis.
・Let's hold disaster drill, evacuation drill and lectures to acquire knowledge about disaster prevention.
・When evacuation warning comes out, call out to the neighborhood and take the initiative in evacuating.
Let's register for disaster prevention information email!
・Disaster prevention information is provided to the registered e-mail address of the registered PC or mobile phone.

２．When heavy rain comes ~ Let's be aware of this point
Let's try to gather information frequently on your own!
Please check the information frequently on the Japan Meteorological Agency website and the Yokohama City website.
・Japan Meteorological Agency website (weather information) (outside site)
・Yokohama City Disaster Prevention Information
Be especially careful when landslide disaster alert information comes out.

Let's be careful about the cliff!
A precursor to a landslide
・Pebbles fall from the cliff.
・New spring water is generated on the slope.
・There is a turbidity of the spring water.
・There is a crack in the slope.
If there is such a precursory phenomenon, take evacuation actions as soon as possible.
In addition, there may be cases where there is no time between the occurrence of a precursor phenomenon to the occurrence of a landslide, or there is no precursor phenomenon.
If you feel danger, take evacuation actions as soon as possible.
Don't overdo it and try to evacuate safely!
When evacuating, wear easy-to-move clothes and try to act with two or more people.
If the surroundings are dark and flooding has already begun, do not forcibly go outside and stay in a high place where you can secure safety, such as the second floor of your home.
Let's evacuate on a safe route!
・When evacuating, avoid roads along rivers, cliffs, and underground roads.
・The gutters and manhole covers on the road may be off due to heavy rain, so be careful and stay away.

４．Areas subject to evacuation warning issued simultaneously with the announcement of "earth and sand disaster alert information" (areas subject to immediate evacuation warning)
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 "Immediate evacuation warning".
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.
Areas subject to evacuation warning and selection criteria are as follows:
