This article is a list of tornadoes that have impacted the central business district (downtown or city centre) of a large city (that is, one having at least 50,000 people, not counting suburbs or outlying communities, at the time of the storm). It is a common myth that tornadoes do not strike downtown areas. The odds are much lower due to the small areas covered, but paths can go anywhere, including over downtown areas. St. Louis, Missouri has taken a direct hit four times in less than a century. Many of the tornadoes listed were extremely destructive or caused numerous casualties, and the occurrence of a catastrophic event somewhere is inevitable. This list is not exhaustive (listing every single tornado that has struck a downtown area or central business district of any city), as it may never be known if a tornado struck a downtown area, or if it was just a microburst (powerful downward and outward gush of wind, which cause damage from straight-line winds), particularly for older events or from areas with limited information. Downbursts often accompany intense tornadoes, extending damage across a wider area than the tornado path. When a tornado strikes a city, it is occasionally very difficult to determine whether it was a tornadic event at all or if the affected area was indeed the "downtown", "city centre", or "central business district" consisting of very high population density and mid to high-rises, as opposed to other heavily urbanized/built-up parts of the city or suburbs. It is sometimes also difficult to determine tornadoes that strike urban cores before 1950, when tornado records (particularly in the US) started to be consistently logged with detail. Before this, lack of details on information from the events, as well as that most cities were far smaller in area and population complicate the record. For the list of cities that are not listed here for certain reasons, see below. == North America == Note: The F-Scale was superseded by the EF scale in the U.S. on February 1, 2007, and in Canada on April 18, 2013 For tornadoes and cities in: United States, Canada, Mexico, Bahamas, Cuba, Central America, and The Caribbean 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「List of tornadoes striking downtown areas of large cities」の詳細全文を読む スポンサード リンク
