Course description and aims
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.
Student learning outcomes
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
Keywords
Earth, Seismic wave, Elastic constant, attenuation, velocity model, fault, fault-plane solution, density, temperature, composition, convection system, volcanism, plate motion
Competencies that will be developed
| ✔ Specialist skills | Intercultural skills | Communication skills | ✔ Critical thinking skills | Practical and/or problem-solving skills |
Class flow
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).
