Ansei earthquake

Japanese: 安政地震 - あんせいじしん

During the Ansei era (1854-1860), there were about 20 earthquakes of various sizes, each causing some damage, including the Nara-Yokkaichi earthquake in June 1854 (July 1854), the Tokai earthquake on November 4 of the same year, the Nankai earthquake on the following day, the Edo earthquake on October 2, 1855 (November 11, 1855), and the Northern Hida earthquake in February 1858 (April 1858). Of these, the Tokai, Nankai, and Edo earthquakes are also known as the Ansei Three Great Earthquakes. The Tokai and Nankai earthquakes are both estimated to have had a magnitude of 8.4, and both earthquakes caused great damage from tsunamis. The death toll from the Nankai earthquake was 2,000 to 3,000, while the death toll from the Tokai earthquake is thought to have been less than this. The Edo earthquake had its epicenter near the mouth of the Arakawa River, and although localized, damage was great, with fires breaking out in over 30 places in the city, the stone walls of Edo Castle collapsing, various gates collapsing, 14,346 houses destroyed or burned, and approximately 7,000 people in the city dead, including Fujita Toko and Toda Houken.

安政年間（1854年―1860年）には，安政１年６月（1854年７月）の奈良〜四日市の地震，同年11月４日の東海地震，翌５日の南海地震，安政２年10月２日（1855年11月11日）の江戸地震，安政５年２月（1858年４月）の飛騨北部地震など多少とも被害を伴う大小20回ほどの地震が発生している。うち東海・南海・江戸地震を安政の三大地震ともいう。東海・南海地震はいずれもマグニチュード8.4と推定され，両地震とも津波の被害も大きく，南海地震の死者は2000〜3000人，東海地震はこれより少なかったと思われる。江戸地震は荒川河口付近を震源とし，局部的だが被害が大きく，市内30余ヵ所に出火，江戸城の石垣がくずれ，諸門が倒れ，壊焼家屋１万4346戸，市中の死者約7000人，藤田東湖，戸田蓬軒らも圧死。
