Education

Overview

Students who would like to carry out their research at the Institute of Seismology and Volcanology (ISV) will belong to one of the four research laboratories: (1) Seismological Observation, (2) Ocean Bottom Seismology and Tsunami, (3) Volcano Physics, or (4) Subsurface Structure. As these laboratories are collaborating closely, students will be provided with a wide range of research opportunities as well as a deep knowledge of their research interests. We believe this is a very important circumstance for bringing up active and productive researchers with a wealth of ideas.

Research at the Institute of Seismology and Volcanology (ISV)

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 understanding the dynamics and evolution of the planet Earth. Earthquakes and volcanoes are so to say surface manifestations of the internal activity of the Earth; thus, understanding their mechanism and processes is one of the essential issues in geosciences.

We have been investigating the physical background of seismic and volcanic activities based on a 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.
