Syllabus

Course overview and goals

This course focuses on earthquakes, magmatism, thermal convection, material transportation, plate motion, and chemical reaction that are ongoing in the Earth.

Students will have the chance to tackle practical problems in the Earth by applying knowledge acquired through this course.

Course description and aims

At the end of this course, students will be able to:
1) understand characteristics of seismic waves
2) understand source process of earthquakes
3) understand seismotectonics beneath Japan
3) understand how to live through earthquakes and volcanic eruptions

Keywords

Earth, Seismic wave, Elastic constant, attenuation, velocity model, fault, fault-plane solution, density, temperature, composition, convection system, volcanism, plate motion
