Outline of Final Research Achievements

Detecting the occurrence of a huge earthquake is one of the greatest goals of humanity. Especially in Japan, there are many active faults in the urban area where many people live and in the coastal area where the power plants are distributed.
In this research, magnetic fields measurement are employed. We develop a system that uses geomagnetic field signals that fluctuate with earthquake faulting, and examine the feasibility in detail. To develop a high-resolution magnetometer system, we conducted long-term precise geomagnetic observations using a high-temperature superconductor based superconducting quantum-interference device (HTS-SQUID) magnetometer system.

Academic Significance and Societal Importance of the Research Achievements

本研究により,実現可能性が明らかとなることで,新しい緊急地震警報システムへ発展することが期待される。巨大地震発生の検知・予測に貢献が出来,地球物理学や地震学だけでなく社会全体へも大きな貢献ができる可能性を秘めている。例えば,医療機関や原子力発電所などの施設にとって,地震発生を1秒でも早く知ることは極めて重要で,それは多くの人命を救うことにつながる。
