Earth Dynamics Lab
Machine-translated · View original
A research field that explores changes in the Earth through seismic waves and rocks.
AboutAbout the lab
Analyzing the Earth's dynamic changes by a variety of methods.
The Earth Dynamics Lab analyzes the Earth's dynamic changes through geophysical big data analysis, field science, laboratory experiments, rheology, and the building of mathematical and analogue models.
It is one of the fields in the Earth Evolution Sciences major of the College of Geoscience.
Faculty members study the earthquake generation processes in subduction zones and the formation of accretionary complexes, earthquake investigations using seismic waves and satellite data, and source process analysis using seismic waveform data.
Graduation research topics include investigations of what happened during great earthquakes and studies of the relationship between rocks and fluids at subducting plate boundaries.
Key terms
- Accretionary complex
- A geological body formed in a subduction zone when material scraped off the subducting oceanic plate is added to the landward side
- Source process analysis
- Analysis that uses earthquake waveform data to investigate how rupture progressed along the fault
- Rheology
- The academic field that studies how materials deform and flow
ResearchResearch themes
The lab investigates the Earth's dynamic changes by multiple methods, including data analysis, field science, laboratory experiments, and model building. Graduation research topics range from analysis of the source processes of great earthquakes to the relationship between rocks and fluids at subducting plate boundaries.
