RESULTS OF OVERLAY ANALYSIS 3.1 Relationship between tsunami damage and tsunami depth Figure 4 and 5 show overlay maps of tsunami damage level and tsunami flooded depth measured by MMS at Yuriage area, Natori City, Miyagi Prefecture and at the Sendai Airport area, Iwanuma City, Miyagi Prefecture, respectirely. These figures show that the area with over 4m tsunami flooded depth is equivalent to the rank 1, and the area with over 1.5m tsunami flooded depth is equivalent to rank 2. Figure 6 shows the distribution of tsunami flooded height measured by field survey results of the 2011 Tohoku Earthquake Tsunami Joint Survey Group (2011) and the authors’ field survey and by MMS of GSI. Tsunami flooded height is calculated by the following formulas: Tsunami flooded height = tsunami flooded depth + LiDAR DEM. The measurement results by MMS correspond well with the measurement results by field survey. Ke 8: Me ar ıng pol (Ualtmt Sd Tr tram (Damage kuel: Rank1 i Hi. SS i Ns LESS SSS Vi S i, 2 ite Figure 4.

Figure7 is overlay map of tsunami damage and landform classification. Figure8 is overlay map of tsunami damage and DEMs. Figure9 is overlay map of tsunami damage and land use. In this section, we describe the outline of landform and land use in Sendai Plain using figure 7 and figure 9. Landform within 1 km area from the coastline is mainly sand dune or sand bar with little higher elevation. Wide sand bars are dominate in the northern area from Abukuma River, but several narrow sand bars are dominate in the southern area from Abukuma River. Landform of inland area over lkm from the coastline is coastal plain or delta. Valley plain or flood plain is dominated along Nanakita River, Natori River and Abukuma River. Natural levee and former river bed are only dominant along main large rivers. Land use on sand dune or sand bar is forest, other farmland and building area. Forest is dominant in the northern area from Abukuma River, however, other farmland is dominant in the southern area from Abukuma River. Land use of inland area over 1km from coastline is mainly paddy field. As building area and other farmland in inland area have zonal distribution along the coastline, these land use located on sand dune or sand bar in inland area. The results of overlay analysis between tsunami damage level and other geographic information are as follows: 1) The completely destroyed area (Rank 1) was located within 1km area from the coastline. Flooded depth of this area is over 4m, and landform classification of this area is almost sand dune or sand bar which has a little higher elevation compared with other area (Figure 7, 8). Contrary to a poor relationship between tsunami damage and landform condition such as landform classification or elevation, there is a good relationship between area of tsunami damage rank 1 and distance from coastline.
