Even though the world is transforming into information-intensive society, the traditional problems related to ‘the earth and resources’, such as shortage of natural resources and energy, global environmental pollution and natural disasters, are getting extremely serious. Engineering geology is, therefore, playing a major role, as a tool to solve such various problems related to the earth and resources facing human beings.
Our laboratory of Earth and Resource System is conducting research on various issues: exploration / development of natural resources, understanding of earthquake occurrence, conservation of the global environment, disaster prevention and civil engineering.
Introduction Video for our lab is now available!!
