Overview of ERI
ERI employs over 80 top-notch academics (professors, associate professors and research associates) drawn from diverse fields, ranging from seismology to volcanology, geophysics, geochemistry, geology, geodesy, applied mathematics, information science, civil engineering and seismic engineering. Together with a support staff of 50, 30 visiting researchers and 70 graduate students, we work on advanced researches, technique development, field observations, experiments, theoretical studies, analyses and computer simulations. We promote comprehensive research and education in order to achieve two goals. 1) Scientifically unraveling the various phenomena within the earth and seismic / volcanic activities on our planet, 2) Mitigation of disasters from such phenomena. Today, the ERI is composed of 4 divisions, 5 centers, and other supporting offices and sections.

Division of Theoretical Geoscience
This division engages in theoretical modeling researches based on basic principles of mathematics, physics, chemistry and geology to understand phenomena related to seismic and volcanic activities.
Division of Monitoring Geoscience
This division engages in research through measurements and analyses of various physical quantities to understand seismic, volcanic and other activities of the Earth's interior.

Division of Earth and Planetary Materials Science
This division engages in research based on information about chemical and physical properties of materials to understand the processes that take place in the Earth and planetary interiors.
Division of Disaster Mitigation Science
This division engages in the investigation and prediction of strong ground motions and tsunamis caused by earthquakes. It also carries out basic studies aimed at mitigating disasters from such phenomena.
* Research Centers:

Earthquake Prediction Research Center
This center carries out research projects for comprehensive understandings of earthquake phenomena and improvement of forecasting future earthquakes.
Volcano Research Center
This center carries out studies on various phenomena to elucidate its elementary processes and fundamental principles, aimed to form the basis for volcanic eruption predictions.
Ocean Hemisphere Research Center
This center studies the ocean hemisphere, which is an observational blind zone, by deploying unique instruments developed in-home. The goal of such observational studies is to elucidate the movements of the mantle and the core, which are the origins of various geological phenomena such as earthquakes and volcanic eruptions, and its driving forces.
Center for High Energy Geophysics Research
This center dedicates efforts to cosmic ray imaging of volcanoes, faults and global earth with high-energy particles such as muons and neutrinos.

Research Center for Large-Scale Earthquake, Tsunami and Disaster
This center studies large-scale earthquake and tsunami as well as urban area disasters, taking advantage of massive numerical simulation.

 *Science Management Centers  

Coordination Center for Prediction Research of Earthquakes and Volcanic Eruptions
This center is responsible for coordination and planning of national and international research projects on predictions of earthquakes and volcanic eruptions.

Center for Geophysical Observation and Instrumentation
This center is responsible for maintenance, management utilization and support for observational, technical and analytical facilities and analytical instruments belonging to ERI. This center also engages in intensive researches based on geophysical observations on land and sea, developing new observational techniques and instrumentation.

Earthquake and Volcano Information Center
This center is responsible for collecting, organizing, and sharing seismic and volcanic data, and works on forming and operating nationwide information and distribution basis. Research activities include development and technology transfer of earthquake disaster information system, international collaborative studies on giant earthquakes, crustal deformation and tsunamis, and establishing the academic base of effective outreach.

*Technical Support Division

This division provides technical support for observational and experimental research conducted by ERI.

*Research and Education Support Offices

Outreach and Public Relations Office
This office works to publicize the results of seismic and volcanic researches and distributes them across the society.

International Research Promotion Office
This office is responsible for planning and coordinating international research projects related to seismic and volcanic activities.

Education and Career Development Offfice
This office works to promote career development for junior researchers and education of graduate students.
Environment and Safety Management Office
This office is responsible for managing environment and safety during observation and research activities within the institute, at observatories and/or during fieldwork.
