Analysis of land cover changing in coastal plain by the 2011 off the pacific coast of Tohoku Earthquake and Tsunami with ALOS satellite images

Extensive damage occurred as a consequence of the earthquake in a large area of East Japan on March 11, 2011, which generated a huge tsunami. Every municipal district town and village in the coastal regions received catastrophic damage due to this tsunami. It is necessary to investigate specially the struck situation in the coastal plain from the viewpoint of the analysis of land cover to clarify the struck characteristics by the tsunami and supporting revival planning for the future. The influences of the tsunami, a time series of changing land cover condition were investigated by using ALOS/AVNIR2 images observed before and after the disaster by the tsunami with land cover classification processing. From these results, the relationship between the land cover and the process of running up the tsunami were considered.
