MAPPING OF BUILDING DAMAGE OF THE 2011 TOHOKU EARTHQUAKE TSUNAMI IN MIYAGI PREFECTURE.

The authors visually inspected the building damage caused by the 2011 Tohoku earthquake tsunami, using the pre and post-event aerial photos. First, we prepared the mosaic of post-tsunami aerial photos acquired by Geospatial Information Authority of Japan (GSI), and conducted the visual inspection of buildings damage to classify the damage. The damage classification results are compiled with building shape files on GIS for mapping the structural vulnerability in the tsunami inundation zone. Finally, we discussed the structural vulnerability in the tsunami affected area based on mapping results of building damage. [ABSTRACT FROM AUTHOR]
