Syllabus
Course overview and goals
This course outlines volcanoes and volcanic activity, which characterize the Japanese archipelago, by introducing the latest examples of eruptions and observations. This course comprises 10 lectures and a day trip session which will be held on Saturday. The main lecture contents are "Introduction to the Volcanology: volcanoes and subduction zones", "Generation of magma and eruption mechanism", "Volcanic hazards and risk mitigation", "Surveying volcanoes: structure of a volcano", "Monitoring volcanoes: volcanic activity", etc.
Course description and aims
[Goal]
Students will learn about the volcano and volcanic activity, which characterize the Japanese Archipelago. Students will understand the basic knowledge about volcanic eruptions, expected volcanic disasters, and a hazard mitigation system, to take appropriate action when they encounter eruptions. In addition, students will learn about several volcanic observation methods to understand the present state of the volcano.
[Theme]
This course provides a wide range of fundamental knowledge about the volcano. The contents cover many topics including the origin of volcanoes, eruption styles, volcanic ejecta, and observation methods. Students will also learn about disasters caused by volcanic eruptions and disaster mitigation. In a day trip excursion, students will visit an active volcano and observe volcanic ejecta and geographical feature of a volcano, through which they will experience a living volcano.
