# Flood and landslide evacuation map
The evacuation map is a map that can help you decide what actions to take and when. It displays the anticipated depth of flooding caused by heavy rainfall that occurs approximately once every 1,000 years, zones in which homes are at risk of destruction, flood duration, and zones in which people are in danger of injury during a landslide disaster. You can determine whether or not it is advisable to shelter in place during a large-scale flood or landslide based on the flood or landslide evacuation determination displayed when you select your location.
Please act on your own judgment
The result of the flood or landslide evacuation determination is based only on one hypothetical scenario. There is no guarantee that actual floods will occur as anticipated. Please act according to your best judgment while paying attention to your surroundings, including the weather, water level, and evacuation information.
# Anticipated flood inundation zones
This map displays anticipated inundation zones based on the river and scale of the flood. It was created by the Kinan Office of River and National Highway, Kinki Regional Development Bureau, MLIT of Japan and Wakayama Prefecture.
Select the river.
Select the scale of the flood.
- Forecast scale
- Flooding due to rainfall in the amount targeted by river development
- Maximum anticipated scale
- Flooding due to heavy rainfall that occurs approximately once every 1,000 years
Select the type of content to be displayed.
- Flood depth
- Maximum floodwater depth
- Flood duration (maximum anticipated scale only)
- Duration of continuous flooding at a depth of 50 cm or greater
# Anticipated tsunami inundation zones
This map displays anticipated tsunami inundation zones based on the “Nankai Megathrust Earthquake” and “Simultaneous Tokai, Tonankai, and Nankai Earthquake” projections announced by Wakayama Prefecture in March 2013.
|Earthquake||Magnitude||Max. Tsunami Height||Arrival Time|
|Simultaneous Tokai, Tonankai, and Nankai Earthquake||8.7||7 m||11 min.|
|Nankai Megathrust Earthquake||9.1||14 m||5 min.|
- Inundation zones
- Display the range of inundation by a tsunami caused by the two types of earthquakes.
- Nankai Megathrust Earthquake tsunami: Inundation depth
- Display the depth of inundation by a tsunami caused by a Nankai Megathrust Earthquake.
- Nankai Megathrust Earthquake tsunami: Arrival time
- Display the arrival time of a tsunami caused by a Nankai Megathrust Earthquake. The arrival time indicates the amount of time it takes after the earthquake occurs for the tsunami to reach 1 cm in depth at that location.
# Flood damage records
This map displays zones that sustained flood damage during past events such as concentrated downpours and typhoons.
You can switch between displaying or hiding the flood damage records of each category.
- Flood damage records are only shown for areas that could be confirmed via photographic interpretation and interviews with residents.
- Flood records prior to the 2011 Typhoon No. 12 (Talas) are shown in the Shingu district only.
# Landslide caution zones
This map displays the landslide caution zones designated by Wakayama Prefecture.
You can switch between displaying or hiding landslide caution zones for each type of disaster.
# Types of landslide disasters
- Collapse of a steep slope
- The sudden collapse of a steep slope that occurs as a result of water seeping into and loosening the slope through the effects of rain, an earthquake, or other factors
- Debris flow
- Rocks and sediment that are swept downstream at once from a hillside or the bottom of a river due to prolonged rain or a concentrated downpour
- The slow sliding down of a wide expanse of land due to the effects of groundwater and other factors
# Landslide caution zones and landslide special caution zones
- Landslide caution zones
- Zones of land where there is a recognized risk of death or bodily harm to residents and other people in the event of the collapse of a steep slope or other landslide disaster. These zones should especially establish a warning and evacuation system in order to prevent landslide disasters.
- Landslide special caution zones
- Zones of land within the above landslide caution zones recognized as posing a considerable risk of death or bodily harm to residents and other people in the event of the collapse of a steep slope or other landslide disaster due to damage to buildings. These zones should set certain limits on development activities and restrict the construction of buildings containing residential units.
# Designated refuge areas and designated emergency refuge areas
This map displays the designated refuge areas and designated emergency refuge areas deemed safe for each type of disaster.
- Designated refuge areas
- Facilities that provide a place for residents and other people who have evacuated from their homes or who are unable to return to their homes due to the danger of a disaster to take shelter (facilities where residents and others who have lost their homes after a disaster can live as refugees)
- Designated emergency refuge areas
- Facilities or locations that have met certain criteria for safety, etc., depending on the type of abnormal phenomenon (such as a flood or tsunami) and can be used as refuge areas to which people can escape from danger when a disaster occurs or is at risk of occurring (facilities or locations for temporary, emergency use in escaping from a disaster)
# Safety level
The number of stars (★) indicates the safety level of a designated refuge area or designated emergency refuge area.
You cannot evacuate to refuge areas that do not have a star (★) during that particular type of disaster.
A shaded star (★) indicates an indoor refuge area, while an unshaded star (☆) indicates an outdoor refuge area.
# Storm and flood refuge areas (flood and landslide disasters)
|★★★||An area that is sufficiently safe from landslides and floods|
|★★||An area where a certain level of safety can be ensured in the event of a landslide or flood|
|★||A refuge area will not be established here when a large-scale disaster is anticipated; a refuge area that is established here may be closed in event of imminent danger|
|★ (Caution)||This area is located in a landslide caution zone; you must aim for a safer evacuation destination|
# Tsunami refuge areas
|★★★||A safe location with no danger of inundation due to its high elevation|
|★★||An emergency refuge area located close to the anticipated inundation zone; to be used only in the event that there is no time to evacuate to a location with a three-star safety level|
|★||An emergency refuge area in danger of inundation; to be used only in the event that there is no time to evacuate to a location with a two- or three-star safety level|
