Point

Comprehensively teaching and researching the global environment

By deepening our understanding of the universe that surrounds the earth, we teach various aspects of the earth as an inter-related series of one system – for example, the atmosphere and water which are essential for our life, composite material and characteristics of the land that supports buildings.

Coexistence of human-being and the earth

Based on knowledge of the global environment, educated personnel will understand the mechanisms of environmental change that threaten human life and the technology to reduce disasters.

Searching the earth and the universe by one’s own hand

We perform training and experiments to deal with various aspects of the earth, such as outdoor surveys and field observations. We have various facilities including earthquake and volcanic observatories, cold region weather laboratories, X-band weather radars to develop our understanding of the universe and the earth.

 

Voice of undergraduate

Being able to study a wide field from the basics to application is appealing.

Department of Earth and Environmental Science 4th grader (2017)
OKADA, Rina

Since I was a high school student, I was interested in earth sciences. I wanted to enter Hirosaki University to study in a wide range of sciences, including the universe, earthquakes, disaster prevention, weather, and geology.
Of these, I was most interested in the geological field. I actually did a geological survey on the west coast area of Tsugaru peninsula, predicting the time of occurrence and scale of a tsunami and high tide by collecting and analyzing samples of sediment, such as measuring the period of a piece of vegetation contained in the soil.
While carrying out research, I try to see things from various angles, and be flexible in my thinking.

Environmental issues and natural disasters:
Dive into various issues of the earth!

Professor UMEDA, Koji

In this department, we aim to understand the nature of various problems that occur between human society and the natural environment by viewing the universe and the earth as one system. From this, we seek to reduce environmental issues and natural disasters, etc.
In the specialized subjects, a wide range of fields can be studied, from sciences such as astronomy, geology, seismology, meteorology, to engineering subjects such as soil mechanics, architectural structural studies, and environmental chemistry.
In this research field, you can contribute to society while connecting with it, through constant monitoring of earthquake and volcanic activities centering in the Northern Tohoku region of Japan, weather observation of the world natural heritage, Shirakami Mountain Range, preparation of a hazard map in case of a volcanic eruption, flooding, and sediment disaster, providing technical support in the creation of a disaster-proof city, and the development of human resources with professional knowledge related to earth science.
