Fig 1.
Area of predicted tsunami inundation and locations of homecare recipients.
Fig 1 depicts areas at risk for flooding by a tsunami in Kochi. Fig 1 was drawn in the GIS by superimposing the layer describing the area of predicted flooding and the layer locating homecare recipients and welfare evacuation shelters. The sea is on the south side of Fig 1 (downward), and a tsunami will proceed from south to north (upward).
Fig 2.
Routes from the homes of homecare recipients to welfare evacuation shelters and routes of visiting nurses traveling to homecare recipients.
Pink lines in Fig 2 represent routes connecting each homecare recipient and the nearest visiting nursing station according to the shortest distance. Evacuation routes connecting welfare evacuation shelters and the homes of homecare recipients are depicted in green on the map.
