| 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. |
|
|
|
|
| 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. |
