Science of Slow-to-Fast Earthquakes

Project Overview

Japan is one of the most earthquake-prone countries in the world. Many earthquakes occur every year, and it is considered that a huge earthquake could occur in the Nankai Trough or directly under the Tokyo metropolitan area in the near future. However, despite the efforts of seismologists, useful forecasts of earthquakes have proved elusive.
The recently discovered phenomenon of slow earthquakes has attracted scientific attention because it may fundamentally change our understanding of earthquakes. During an earthquake, underground rock ruptures quickly, radiating strong seismic waves that shake the ground. During slow earthquakes, the underground rock also ruptures, but slowly, so the shaking is very weak, sufficiently weak that these earthquakes have been overlooked until this century, with the development of highly sensitive instrumentation for seismic detection. Research during the last two decades has discovered slow earthquakes in various regions worldwide and has established some of their characteristics. However, their relationship to the occurrence of huge earthquakes, a topic of paramount concern, is not well understood. Therefore, we have launched a research project to broaden and deepen our understanding of earthquakes ranging from slow earthquakes to fast (ordinary) earthquakes. This is a Grant-in-Aid for Scientific Research Project [Grant-in-Aid for Transformative Research Areas (A)] of MEXT, Japan, entitled “The Science of Slow-to-Fast Earthquakes”.
To enable these researchers from various fields to collaborate effectively, six planned research subgroups have been established in the research area (see below schematic figure). These are the A01 Physicochemical Processes Group, A02 Structural Anatomy Group, A03 International Comparison Group, B01 New Technology Observation Group, B02 Information Science Group, and B03 Modeling and Forecast Group. In addition, we are calling for publicly offered research proposals every two years. Approximately 100 researchers, and many students who will lead the next generation of scientists, will work within this five-year-long research project to understand both slow and fast earthquakes and better forecast their future occurrence.

Earth-Life Science Institute (ELSI)

Earth-Life Science Institute — Search for the Origin of Earth and Life
The Earth-Life Science Institute (ELSI) of Institute of Science Tokyo, established in 2012, is a member of research centers of the World Premier International Research Center Initiative (WPI) Programme of the Ministry of Education, Culture, Sports, Science, and Technology (MEXT). ELSI’s mission is to discover the “origins of the Earth and life” through an integrated interdisciplinary approach that brings together top-level domestic and international researchers in fields such as Earth science, life science, and planetary science. ELSI investigates questions such as how Earth formed in the solar system, how life originated on Earth, and how life and the Earth arrived at their present forms. Furthermore, ELSI also considers how life might exist in other planetary systems based on this understanding of how Earth and life on Earth originated.

ELSI Graduate Course　[Introduction to the Graduate Programme in Earth-Life Science]

In April 2022, ELSI established a new graduate programmes in Earth-Life Science. This is one of the few integrated five-year Masters-PhD programmes provided fully in English in Japan. Students will receive both a Master’s degree and a PhD degree upon completion (upon completion of both a Master’s and PhD dissertation and defence in the second year and fifth years, respectively). ELSI has a target to accept up to 10 students per year (~5 Japanese, 5 international1) with financial support available (vide infra). Students will be affiliated with and formally supervised an ELSI Principal Investigator2 (PI) from one of the following departments:

ALMA project
Thirty Meter Telescope

ALMA project

ALMA is one of the world's largest radio telescopes located in Chile, consisting of 66 antennas.

Constructed and operated with international cooperation led
on behalf of Europe by ESO,
on behalf of North America by NRAO,
on behalf of East Asia by NAOJ.

2023 marks the 10th anniversary of its inauguration!

Radio wave observations with ALMA allow us to observe dust and gas which are the material of planets.
ALMA can observe them with unprecedented high angular resolution and high sensitivity.

Thirty Meter Telescope

TMT is an ambitious project with plans to construct on Hawai`i an extremely large telescope with an aperture of 30m with the cooperation of five countries including Japan. The major goals of TMT include search for signatures of life on extrasolar planets and the history of our solar system.

◆TMT Overview

In Search for Life on Extrasolar Planets

◆Direct observations of Earth-like planets
Many planetary systems around stars other than our Sun are being discovered today, and we are learning that there exist planets with various sizes and orbits. Recently, planets similar in size as Earth have been discovered, indicating that there are planetary systems much like our own Solar Sytem. Today, infrared observation has advanced to a point of being able to actually capture images of these planets.

◆Are we alone?
Are there extrasolar planets with existence of life? This is a question common to all humanity. TMT aims to discover signs of life on these planets.

TMT will be able to study the composition of the atmosphere of extrasolar planets through spectroscopic observation. Discovery of oxygen molecules and organic substances could be a signature of existence of extra-terrestrial life.

Our Solar System

The advent of TMT will enable us to tackle long-standing questions concerning the formation of the solar system, the origin of planetary volatiles, the physics of the ice and gas giants, and the unraveling of the complex dynamical history recorded in the Kuiper belt.

Science Teams

The TMT International Science Development Teams (ISDTs) are groups of researchers who work together to provide scientific guidance and feedback to the TMT project, to stimulate planning for future TMT observing programs, and to build connections between the TMT and the international astronomical communities. The ISDTs foster scientific collaboration across the TMT partnership and beyond, into the broader astronomical community. Prospective applicants are encouraged to contact the conveners to learn more about the ISDTs and their activities.

ISDTs (TIO website)

Maunakea and TMT

TMT is planned to be built on Maunakea, Hawai`i. Maunakea is a 4000-m mountain with gently inclined slopes, isolated in the mid-Pacific Ocean from any other land mass, which makes the mountain one of the exceptionally well-endowed sites for astronomical observations in the world. Maunakea is also a sacred place for the people of Hawai`i, connecting them to their k?puna (ancestors) and akua (gods). It represents a symbol of the Hawai`i culture deeply rooted in nature. We are committed to the TMT Project without impeding traditional and customary cultural practices of Hawai`i.
