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.
At the end of this course, students will be able to:
1) Understand global structures (seismic velocity, density, composition, temperature, rheology)
2) Understand global dynamics （plate motion, mantle convection, thermal evolution) and overview of actual phenomena
3) understand characteristics of seismic waves
4) understand source process of earthquakes
5) understand seismotectonics beneath Japan
Earth, Seismic wave, Elastic constant, attenuation, velocity model, fault, fault-plane solution, density, temperature, composition, convection system, volcanism, plate motion
|Intercultural skills||Communication skills||Specialist skills||Critical thinking skills||Practical and/or problem-solving skills|
The first 7 classes introduce large-scale structure and dynamics in the Earth (Lecturer is Prof. Iwamori), and subsequent 8 classes focus on seismic wave propagation and source process of earthquakes (Lecturer is Prof. Nakajima).
