Kageyoshi Noro heard that the building of the Iron and Steel Institute of Japan collapsed in the Great Kanto Earthquake of September 1, 1923. He died several days later, on September 8, 1923. Kageyoshi Noro Kageyoshi Noro (, October 17, 1854 - September 8, 1923) was a Japanese metallurgist who contributed to the modernization of Japan's steel industry. Kageyoshi Noro was born in 1854 in Nagoya, Japan. After finishing his primary education in Nagoya and his secondary education in Tokyo, he studied mining and metallurgy at the college, which would later became part of Imperial University of Tokyo. After graduation in 1982,
2011 Tōhoku earthquake and tsunami and south. From the averaged coupling coefficient of 0.5–0.8 in the source area and the seismic moment, it was estimated that the slip deficit of this earthquake was accumulated over a period of 260–880 years, which is consistent with the recurrence interval of such great earthquakes estimated from the tsunami deposit data. The seismic moment of this earthquake accounts for about 93% of the estimated cumulative moment from 1926 to March 2011. Hence, earthquakes with magnitudes about 7 since 1926 in this area only had released part of the accumulated energy. In the area near the trench, the coupling coefficient
