Students who would like to carry out their researches at chair of Seismology and Volcanology (ISV) will belong to one of the four research laboratories: (1) Seismological Observation, (2) Ocean Bottom Seismology, (3) Volcano Physics, or (4) Subsurface Structure. As these laboratories are collaborating closely, students will be provided a wide range of research opportunity as well as deep knowledge on their research interests. We believe this is a very important circumstance for bringing up active and productive researchers with a wealth of idea.
When, where, why and what size of earthquakes and volcanic eruptions will take place ?
While earthquakes and volcanic eruptions are often a public concern, threatening our social basis, they can also be important clues to understand the dynamics and evolution of the planet Earth. Earthquakes and volcanoes are so to say surface manifestations of the internal activity of the Earth; and thus, understanding their mechanism and processes is one of the essential issues in geosciences.
We have been investigating physical background of seismic and volcanic activities based on multi-disciplinary approach, including seismology, geodesy, geothermics, fluid dynamics, electromagnetics, geology, and so on, in collaboration with domestic and international universities and research institutes.
For students, Hokkaido provides good opportunities to apply a wide range of knowledge that you have learned, such as physics, chemistry, mathematics as well as earth science, to real earthquakes and volcanoes.
