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 intensities were smaller than the actual ones in some places, especially in Kanto, Koshinetsu, and Northern Tōhoku regions where the populace warning did not trigger. According to the JMA , reasons for the underestimation include a saturated magnitude scale when using maximum amplitude as input, failure to fully take into account the area of the hypocenter, and the initial amplitude of the earthquake being less than that which would be predicted by an empirical relationship. There were also cases where large differences between estimated intensities by the Earthquake Early Warning system and the actual intensities occurred in the aftershocks and
