Geodynamics Research Center (GRC), PIAS, Ehime University

Introduction of GRC

Leading institute of high-pressure sciences brochure

◆Earth, Planetary and Materials Sciences

Geodynamics Research Center (GRC) is an international research institute where researchers conduct leading-edge studies on materials and states of the Earth's deep interior in order to reveal dynamics and evolution of the Earth and planets, based on advanced high-pressure experiments and numerical simulations. We investigate various issues of the Earth and planetary sciences, chemical composition of the Earth's lower mantle, materials and structures of the Earth's core, Earth's deep water, internal structure of solar planets and exoplanets and dynamics of the planetary interior, and expand our techniques and knowledge to a field of material sciences for synthesizing novel useful materials such as the world-hardest material "HIME-Diamond".

The radius of the Earth is about 6,400 km, but only 10 km depth is achieved by drillings. The Earth's deep interior is an unreachable place where pressure and temperature at the center are estimated to be respectively 360 GPa and 5000 K or higher. Thus, high-pressure and temperature experiments and numerical simulations are essential tools to study dynamics and composition under such extreme conditions. Developments of the techiniques at GRC lead to an innovative area of high-pressure materials sciences; syntheses of newly novel materials which are obtainable only by high pressure experiments.

◆PRIUS: Premier Research Institute for Ultrahigh-pressure Sciences

GRC operates PRIUS from 2013 which is one of the "Joint Usage / Research Centers" in Japan authorized by the Ministry of Education, Culture, Sports, Science and Technology. Missions of PRIUS, as an international education and research hub, are to conduct Earth and planetary science and material science research by using the high-pressure techniques with the objective of creating new fields of science thorough the international collaborations and interdisciplinary networks of researchers.

How to explore the Earth's deep interior under extreme conditions brochure

◆High-pressure and temperature experiments

GRC conducts experiments under conditions of ultra high pressure and high temperature experiments of the Earth's and planetary deep interiors by using two types of high-pressure generationg appaturs: Munti-anvil high-pressure apparatus and Diamond anvil cell apparatua. GRC is equipped with several types of Multi-anvil apparatus, including the world-largest class one of 6000-ton press, BOTCHAN.

◆Phase transitions of minerals

A “phase transition” is characterized by the change of configuration of a toms in mineral by the effect of pressure. Diamond is a high pressure form of graphite, whose phase transition occurs at 5 GPa (150 km depth). Measurements of the conditions where the phase transitions occur and changes of the physical properties of minerals (density, sound velocity, chemical properties etc) accompanying the phase transition bring fruitful information for understandings of the Earth's deep structure and materials.

◆Numeral simulations

Ab initio computations: Theoretical and computational investigation on the
ultrahigh-pressure behaviors of materials in the Earth and planets are conducted by using computer simulations based on quantum mechanics.

Fluid mechanics computation: Numerical simulations based on the fluid and continuum mechanics are conducted to reveal the convective motions in the mantle and core of the Earth and terrestrial planets for the understandings of the dynamics and evolution processes of the planets. Large scale computations using realistic parameters of the Earth, phase transitions, viscosity and compression behaviors under high pressure, are performed for 3-D spherical-geometry simulations.

Ultra-hard material HIME-Diamond and creation of novel materials brochure

◆What is HIME-Diamond?

HIME-Diamond synthesized in GRC is the hardest diamond and likely the hardest material in the world. Unlike normal diamond made of a single
crystal, HIME-Diamond consists of closely-packed nanometer-sized diamonds (~10 nanometers = one hundred-thousandth millimeters). Thus the HIME-Diamond is also called "Nano-polycrystalline diamond (NPD)".

◆Toward higher pressure generations

Experiments under higher pressure are of importance to investigate the interiors of the Earth and planets. The harder the compression material is, the higher the pressure we can reach and thus HIME-Diamond plays a
major role in future development of experiments at ultrahigh pressure. The high transparency of HIME-Diamond enables high-pressure experiments using optical in-situ observations and synchrotron radiations.

◆Novel polycrystalline materials and gems

GRC conducts syntheses of novel polycrystalline materials by applying techniques learned from making of HIME-Diamond. Nano-polycrystalline
stishovite (NPS) made from silica (SiO2) is one of the novel materials synthesized by GRC. NPS shows excellent physical properties having both hardness and toughness. Garnets (one of the main constituents within the Earth) with a variety of chemical compositions can be synthesized as nano-polycrystalline materials.

Research Institute for Marine Geodynamics, JAMSTEC

Understanding of Earthquakes and Volcanic Activity to Mitigate Disasters

To understand and reduce the impact of earthquakes, volcanic eruptions, and tsunami disasters along the subduction zones of Japan, we conduct comprehensive research that encompasses not only surface phenomena but also deep Earth processes such as energy transfer and material circulation that drive plate motion.
In collaboration with national agencies and universities, we carry out seafloor surveys and observations around Japan and the Pacific Rim using research vessels and advanced observation systems.
We are also developing analytical methods based on real-time monitoring technologies and subsurface structural models to understand ongoing seismic, volcanic, and tsunami activities.
By integrating and analyzing observational data, we aim to provide scientific information to relevant national bodies, including the Headquarters for Earthquake and Volcano Research Promotion, thereby supporting disaster prevention and mitigation measures of the government and local authorities.

RESEARCH

■Investigating Geodynamic Processes in Plate Subduction Zones through Marine Geophysical Observations

Plate subduction zones, extending from the incoming oceanic plate to the back-arc region, are areas where diverse geodynamic processes occur, including devastating earthquakes and tsunamis in the forearc and back-arc regions and volcanic eruptions along island arcs. To better understand these processes, we aim to elucidate subsurface structures, seismic and volcanic activity, and their temporal variations through marine geophysical observations, making full use of research vessels and deployable seafloor geophysical instruments. Our study areas include subduction zones not only in Japan but also around the world through international research collaborations.

■Deciphering Earthquakes, Tsunamis, and Volcanic Activity from Rocks and Sediments

Earthquakes, tsunamis, and volcanic eruptions in marine environments can cause sudden and large-scale disasters. To understand the preparatory processes and subsequent evolution of these geological phenomena, it is essential to decipher past occurrences and the Earth’s internal processes from geological records preserved underground and on the seafloor.

We therefore investigate rocks and sediments that retain evidence of past seismic and volcanic activity, using cutting-edge geochemical and geophysical analyses to reconstruct their event histories and to elucidate the Earth’s internal processes.

Furthermore, by incorporating simulations and AI-based methods, we aim to clarify the generation and transport processes of heat, magma, and fluids within the Earth and to advance our understanding of subduction zone dynamics.

■Understanding of Spatio-temporal Variations of Offshore Seismic and Volcanic Activities through Real-Time Monitoring

Real-time monitoring of seafloor and subsurface processes provides a better understanding of the stress state of plate tectonic boundaries such as the Nankai Trough, and of magmatic activities at offshore volcanoes in regions like Izu-Ogasawara. We are developing analysis methods that combine cutting-edge monitoring data with underground structural models to reveal the spatio-temporal variations of seismic and volcanic activity. In addition, we aim to enhance prediction methods for earthquakes, volcanic eruptions, and tsunamis triggered by these geodynamic events. Based on these efforts, we are constructing an integrated system encompassing real-time analysis of geodetic and geophysical data, as well as the framework for disseminating resultant information.

Tokyo Geographical Society

◆What is TGS (the Tokyo Geographical Society)?

The Tokyo Geographical Society (TGS) founded in 1879 is a long-established Japanese academic society. In 2025, its membership totaled ca. 650 professionals, comprising scientists, teachers, and engineers, active in fields including geology, mineralogy, geography, geophysics, and geochemistry. The founding concept of TGS is to contribute to the advancement of the geosciences over a wide range of related fields encompassing the natural and social sciences, humanities, and engineering, and to promote the public dissemination of research results in the geosciences.

Although we have no regular meetings for presenting research papers as usual academic societies, we have continued to carry out a wide range of activities as below:

1. Enhancing public awareness on geosciences
1) Scientific lectures, excursion and geotours
2) Collecting books and literature related to geosciences and compiling the history of geosciences
3) Introduction of geo-experts among the society members to the public as lecturers, committee members, geotour guides, etc.
4) Cooperation and contact with related academic societies
5) Publicity activities through website

2. Publishing and distribution of geoscience journals and publications1) Editing and publishing the official journal: Journal of Geography (Chigaku Zasshi)
2) Distribution and selling publications of the society

3. Grant and award programs for researches and outreach activities
1) Grants for geoscience researches, international geoscience meetings, and outreach activities and publications
2) Awards for individuals and groups within Japan and abroad, who are significantly contributing to the development and dissemination of geoscience.

TGS Website

◆History of the Tokyo Geographical Society

Soon after the Meiji Restoration in 1868, four diplomatic and cultural envoys-statesmen and scholars Hiromoto Watanabe (1848–1901), Takeaki Enomoto (1836–1908), Naohiro Nabeshima (1846–1921), and Moriyoshi Nagaoka (1842–1906)-were dispatched on missions to countries in West Europe and Russia. They all came to realize the important roles the geosciences played in the development of these advanced nations. Having joined Royal Geographical Societies in Vienna,
London, and St. Petersburg during their stays in Europe, and they felt there was a strong need to establish a similar society in Japan. Upon returning to Japan, they founded the Tokyo Geographical Society on April 18, 1879. Modeled after the Geographical Society of London (the Royal Geographical Society), its purpose was to contribute to the modernization of Japan. Imperial Prince Yoshihisa Kitashirakawa (1847–1895) accepted an invitation to be the first president.

◆Journal of Geography (Chigaku Zasshi)

The publication of TGS at the time of its founding, the Report of the Tokyo Geographical Society, was succeeded by the Journal of Geography (Chigaku Zasshi), which was first issued in 1889. Six issues a year volume, the latest issues and editorial and submission guides, can be accessed at the journal website of TGS. All issues and papers since 1889 are archived on J-STAGE. The number of papers downloaded each month in recent years has exceeded tens of thousands, indicating the high degree of recognition our official journal.

Special issues on themes of particular interest to geoscientists, focus mainly on the Japanese archipelago and the Asian region as a whole. Distinguished geoscientists engaged in a wide range of fields provide valuable review papers summarizing the frontiers of their research. Published in color, examples of recent issues are shown below:
Journal Archive

◆Public Lectures and Geoscience Club

Open scientific lectures are held regularly in spring and autumn. Geo-experts give easy-to-understand explanations on topics of broad interest to the general public, such as natural hazards, climate change, and natural resources, as well as interdisciplinary issues. Announcements, abstracts, reports, and materials related to the lectures are available on TGS website (Lectures and Geoscience Club) and in Journal of Geography to provide records of our activities.
Geoscience Club is a few times a year lecture event designed to promote the geosciences, as well as to serve a social function for members and guests. Geoscientists engaged in first-rate research are invited to present state-of-the-art research results in a relaxed, salon-like atmosphere at the auditorium of the Chigaku Kaikan (in central Tokyo). This series of lecture events has been held since 1961.

◆Geotours and Excursions

The Society conducts geo-tours and field trips once or twice a year in Japan for the Society members and the general public.

Information and reports on the geotours and field trips are posted on TGS website (Geotours and Field Trips) and in Journal of Geography.
In 2026, map lectures and geotours will be held for 8/18, 10/18, and 11/15.
