Department of Geology

Introduction to Department of Geology

The earth on which we live is very active. The Great Hanshin Earthquake in 1995 and recent eruptions of the Usu and Miyake-Jima volcanoes revealed that the earth is active and dynamic. Recently the crisis of earth environments occupies the interest of many people. It is very important to understand various natural phenomena on the present earth and mechanism governing the phenomena to cope with such problems. It is also significant to know the historical variation of the earth since its birth. The earth has undergone various changes since its birth and developed life on the surface to the present states. A life and living thing have experienced to many crises of mass extinction and changed into new style.
Geology has greatly contributed to understand such natural processes and mechanism controlling the changes. Also geology gives a fundamental base of exploration and development of mineral resources, petroleum, and geothermal energy. Furthermore, geology is a basic science to understand, prospect and cope with earthquake, volcanic eruption and natural hazards such as landslide.
Members of the Department of Geology study the nature and formation process of strata, rocks and minerals that constitute crust and mantle, the change and evolution of life, and the history and mechanism of change of the earth. Thus we face problems ranging from a familiar material to global scale. One of characteristics of our department in terms of educational system is careful teaching to small number of students.
