Abstract
In recent years, satellite imagery has become a very useful tool for managing disasters and protecting the environment. When disaster happens, satellites can give reliable information about how serious is the disaster and where the area that are affected. Satellite imagery covers extensive surface areas and provides near real-time data, it helps agencies access remote or inaccessible regions. In this study, we focus on earthquakes that hit Ishikawa in Japan and eastern island of Taiwan earlier this year. When disaster occurred, FORMOSAT-5 responds quickly for providing imaging and value add products. Additionally, we also obtained valuable satellite data through collaborated with sentinel Asia, including Japan, Thailand and India. To identify the impacted area, we compared pre and post scenes with visualize change analysis rapidly to provide availability of information for decision-making. Soon afterwards, Numerical analysis was also provided. As the result, we were able to identify buildings were damaged in Wajima City and new exposed land extending along with coastline, on the other hand, large-scale landslides and a barrier lake have been discovered in mountainous areas of Taiwan.
