Course description and aims

This course outlines volcanoes and volcanic activity, which characterize the Japanese Archipelago, introducing the latest eruption examples and observation examples. This course is comprised of (1)six lectures and a three-day outdoor training session which will be held during the exam period or the summer vacation. The main lecture contents are "Introduction to the Volcanology: volcano and subduction zone", "Volcanic eruptions 1: variety of eruptions", "Volcanic eruptions 2: volcanic ejecta", "Volcanic hazards and risk mitigation", "Surveying volcanoes: structure of a volcano", "Monitoring volcanoes: volcanic activity". The main training contents are "Observation of the lava flow, pyroclastic flow, volcanic ashes, and other geographical features of a volcano", "Collection of the volcanic gases or hot-spring water and its chemical analysis", "Exploration of the underground structure by electrical resistivity measurement".

Student learning outcomes

[Goal]
Students will learn about the volcano and volcanic activity, which characterize the Japanese Archipelago, from lectures and outdoor training. Students will understand the basic knowledge about volcanic eruptions, expected volcanic disasters, and a hazard mitigation system, in order to take an appropriate action when they encounter eruptions. In addition, students will learn about several methods of the volcanic observation to understand the present state of the volcano, and will deepen their understanding of it through the outdoor training.
[Theme]
This course gives the fundamental knowledge about the volcano widely. The contents cover many topics including the origin of volcanoes, eruption styles, volcanic ejecta, and observation methods. Students will learn about disasters caused by volcanic eruptions and the disaster prevention, as a natural disaster. In the outdoor training, students will visit an active volcano and observe volcanic ejecta and geographical feature of a volcano, through which they will experience a live volcano.
