Abstract
The vegetation of Miyake Island has been widely effected by the volcanic eruption in July 2000. This phenomenon is still going on and much of the vegetation cover has been changed. It is quite important to monitor the vegetation recovery process because of ecosystem study, prevention of disaster and rehabilitation of the Island. This study investigated an evaluation of the vegetation recovery process in Miyakejima Island after the 2000 volcanic eruption using satellite remote sensing and field vegetation survey. Multi temporal 12 satellite images of Terra/ASTER and JERS-1/OPS were selected and combined into three time series datasets such as the before eruption, the after eruption within two years and the after eruption more than three years. These three time series image datasets were analyzed into the seamless images of the maximum NDVI value. According to the unsupervised classification of these three images, Miyakejima Island was divided into six classes with vegetation change patterns. These results followed past works and field vegetation survey well. The classes were recognized with the vegetation change which shows the damage of trees and the recovery of vegetation after the volcanic eruption of the year 2000.
