Course description and aims

The first half of the course explains transfers of materials and processes of chemical reactions associated with volcanic activities. In the latter half, roles of water on volcanic activities are discussed on the basis of various perspectives.

Student learning outcomes

Acquisition of basic knowledge for chemical characteristics and reaction of gas, liquid and solid associated with volcanic phenomena


geochemistry, volcanic gas, volcanic eruption, disaster prevention

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

Theme-based lectures with the aid of original pictures and movies

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.


Not specified.

Reference books, course materials, etc.

Handouts will be distributed at the beginning of class when necessary.

Assessment criteria and methods
