Abstract
The advancement of remote sensing technology has contributed to a significant level of assistance in reducing nature's calamities, threatening both human lives and property in its immediate vicinity. Volcanic eruption is one of a kind where the dangerous environment surrounding it also causes great difficulties for close-up monitoring and surveillance. Differential Synthetic Aperture Radar Interferometry (DInSAR) is a technique useful for accurately detecting the ground displacement or land deformation in the antenna line-of-sight (slant-range) direction using synthetic aperture radar (SAR) data taken at two separate acquisitions. As one of important targets of the DInSAR analysis, we have studied the volcanic eruption of Miyakejima island, successfully demonstrating the detection of land deformation around its crater.
