Abstract

The Tohoku earthquake of March 11, 2011, caused very huge tsunamis and widespread devastation. Various very highresolution satellites quickly captured the details of affected areas, and were used for disaster management. In this study, very high-resolution pre- and post-event Geoeye-1 satellite images were used to identify damages. Change detection procedure was used to obtain estimation from the damages. However based on the selected zone and the number of categories selected for the change detection some variability was detected in the results. This paper analyses the effects of these parameters on the change detection results and discuss about the amount of errors and also the correlation between the results for different zones selection. It was observed that the amount of changes vary based on the selections and there is no linear relation between the quantitative results. This issue was investigated through various examples using 2011 Tohoku, Japan earthquake with very high resolution satellite images.
