Effects of climate change on geo-disasters in coastal zones and their adaptation

Results of recent investigations suggest that climate change tends to exacerbate geo-disasters. Therefore, it is understood clearly that adaptation to climate change has rapidly become the most important and urgent issue for the future existence of human beings on Earth. These inferences form the background of this research. In comparison to those examining water disasters, few studies have examined climate-change-induced geo-disasters. This study aims at upgrading the methodology for estimating effects on geo-disasters of combined events, e.g., global warming with increased typhoon and rainfall severity or occurrence of great earthquakes. Such a methodology is expected to contribute to progress in the fields of natural disaster mitigation and land preservation, particularly near seacoasts and rivers.
