Course description and aims

Advanced lectures dealing with chemical processes of volcanic phenomena as drastic emission of material and energy related to geophysical phenomena.

Student learning outcomes

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

Keywords

geochemistry, volcanic chemistry, 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

Chemical reactions among gas, liquid, and solid phases at active volcanoes in the first half of the course. Thermal activity of active volcanoes in the latter half of the course.

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.

nothing special

Reference books, course materials, etc.

Handouts will be distributed at the beginning of class when necessary
