Ocean Hemisphere network Project "Ocean Hemisphere network Project" constructs an observation network and performs researches aiming at the discovery that will yield the creation of new earth's view in solid earth science field. Our goal is to reveal global activities of the earth based on the data obtained from newly established network in the ocean hemisphere, centered on the Pacific, that observes earth activities synthetically (based on seismology, geomagnetism, geodesy, tsunami and crustal deformation). |

Mt. Fuji Project (Japanese only) Although Mt. Fuji is very famous, most matters are not clear about Mt. Fuji. Since Fuji volcano has been being dormant for a long period, it has not been revealed how magma accumulates and proceeds to eruption and whether the process is same as other volcanoes that frequently erupt or not. The eruption style is also varied such as from explosive one to quiet one, and it is not clear how the eruption style is selected. We are performing the researches that how we should release the information about the subject related to the bare bones of volcanology and about volcanic activities to society as the cooperative research with volcanologists and sociologists of the whole country. |

Special Project for Earthquake Disaster Mitigation in Urban Areas The target of this research is prediction of strong ground motion, and we perform researches about 1. Deep seismic explorationm, 2. Deep drilling, and 3. Characterization of earthquake faults and crustal structure, with Disaster Prevention Research Institute, Kyoto University, National Research Institute for Earth Science and Disaster Prevention, and so on. The purpose is the construction of fault model to predict strong motion accurately. For this purpose, we research large-scale crustal structure in order to reveal the mechanism of generation of large earthquake that yield great damage in metropolitan area such as southern Kanto plain where determination of the source of earthquake generation is difficult. |

Seismic Experiment for Volcanoes (Japanese only) Volcanological researches revealed that appropriate observation can detect the unusual signals preceding eruptions at most volcanoes. Even if the unusual signals are observed, however, we can not know accurately whether the eruption trully occurs or not, what the eruption style is, and what the scale of eruption is, because we do not know the state of magma: where and how much magma accumulates beneath the volcano. Thus, we have been performing seismological exploration of volcanoes since 1994 as the main theme of prediction research on volcanic eruption with volcanologiste of the whole country in order to know how the underground of volcanoes is, where magma is, and what the relation between unusual signals preceding eruption and underground structure of volcanoes. |
The ERI is promoting various research projects as a shared institute of Japanese universities.
