1923 Great Kantō earthquake space in which an estimated 38,000 people were killed by a single fire tornado. The park houses a Buddhist-style memorial hall/museum, a memorial bell donated by Taiwanese Buddhists, a memorial to the victims of World War II Tokyo air raids, and a memorial to the Korean victims of the vigilante killings. In Yasunari Kawabata's 1930 novel "The Scarlet Gang of Asakusa" several chapters deal with the Great Kantō earthquake. In "Japan Sinks", in one scene in the book, due to the fast-moving subduction of the Pacific and Eurasian plates, the Sagami Trough ruptures in a magnitude-8.5 earthquake, killing several million
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
