Hokkaido, which is located in the northern part of Japan, has two plate boundaries – between Pacific Plate and Okhotsk Plate (North American Plate) off south-east of Hokkaido and Okhotsk Plate and Amurian Plate (Eurasian Plate) in the west. This tectonic setting makes Hokkaido one of the most active areas on seismic and volcanic activity in the world. Institute of Seismology and Volcanology (ISV) is the research institute for elucidating the mechanisms behind earthquakes and volcanic eruptions and promoting research studies to prediction technology.

Message from the Director

Institute of Seismology and Volcanology(ISV) at Faculty of Science in Hokkaido University was established in 1998. Based on the national plan for prediction of earthquakes and volcanic eruptions, observational researches to study volcanic, earthquake and tsunami activities has been carried out in this institute. The researchers in our institute are eager to understand the occurrence of devastating earthquakes and volcanic eruptions to reduce disasters. We installed many observation systems such as seismometers, tilt-meters, strain-meters, GPS, tide gauges, etc, in and around Hokkaido. We also carry out several campaign surveys using various geophysical instruments in summer time every year. Students who are interested in large earthquakes, volcanic eruptions, or tsunamis, and like to use geophysical instruments in the field are welcome to join us.
