The Sudbury tornado was an F3 tornado, which hit the Canadian city of Sudbury, Ontario, at approximately 8:30 a.m. on August 20, 1970.〔C.M. Wallace and Ashley Thomson, ''Sudbury: Rail Town to Regional Capital''. Dundurn Press, 1993. ISBN 1-55002-170-2.〕 It is currently tied for the status of the eighth deadliest tornado in Canadian history. ==Storm== Considered unusual because tornadoes of this strength rarely occur in Northern Ontario,〔("1970 Sudbury tornado" ). ''Sunday Magazine'', CBC Radio, August 23, 1970.〕 the tornado touched down in the suburban community of Lively. The tornado tracked quickly eastward into the city, hitting the neighbourhoods of Copper Cliff, Robinson and Lockerby over the next ten minutes. Another tornado associated with the same storm also hit the community of Field, approximately 50 kilometres east of Sudbury, less than an hour later. The storm continued through North Bay, uprooting some trees in the wilderness but avoiding any damage to the city.〔"90 mile winds smash Sudbury area". ''Toronto Star'', August 20, 1970. p. 1.〕 It then tracked southeasterly toward Ottawa, leading the federal government to order a precautionary shutdown of its offices in the capital,〔"Ottawa concerned". ''The Globe and Mail, August 21, 1970. p. 8.〕 but the storm weakened around Chalk River and only a few millimetres of rain actually fell on Ottawa by the time it reached that city.〔 Residents of the region had little warning of the storm as the Sudbury Airport did not at the time have weather radar capable of detecting tornado activity,〔("1970: Deadly tornado tears through Sudbury, Ontario" ). The Weather Network, August 20, 2012.〕 and the day's only weather forecast was for "showers".〔"Forecast was for 'showers'". ''The Globe and Mail'', August 21, 1970. p. 1〕 The first public indication of the twister, instead, was a phone call to CKSO from a woman frantically reporting that her house was blowing away.〔("1970: Freak tornado kills six in Sudbury" ). ''The National'', August 20, 1970.〕 Six people died and 200 were injured in the tornado, which caused an estimated $17 million ($ in dollars) in damage,〔 including to Inco's copper smelter in Copper Cliff. A pipeline carrying iron-nickel concentrate to the plant collapsed onto a train track below, in turn causing a derailment when a train hit the collapsed pipe, but the incident resulted in only minor injuries.〔"Damage high but INCO 'got off lightly'". ''Toronto Star'', August 21, 1970. p. 3.〕 The Inco Superstack, then under construction, swayed in the storm but was not heavily damaged.〔 Six workers were on the construction platform at the time; although all six survived, they quit their jobs the next day.〔"6 nearly blown off 1,250-foot smokestack so they quit their jobs". ''Toronto Star'', August 21, 1970. p. 2.〕 Minor damage was also reported to the Big Nickel, with some pitting of the stainless steel panels as rocks and debris hit the monument, although that structure also survived.〔("'It's the end of the world'" ). ''Sudbury Star'', August 16, 2010.〕 Damage was also reported to Memorial Hospital, Glad Tidings Tabernacle, and over 300 homes in Lively, Sudbury and Field.〔"5 dead as 80-mph winds batter Nickel Belt". ''The Globe and Mail'', August 21, 1970. p. 1.〕 Some streets in the affected neighbourhoods were flooded by up to a foot of water, and electrical and communications infrastructure was heavily damaged. For several days after the storm, amateur radio remained the only reliable method of communication into and out of the city.〔"Sudbury phone lines still bad; CNE hams send messages". ''Toronto Star'', August 21, 1970. p. 8.〕 In Field, a lumber mill which was the town's primary employer was heavily damaged,〔"6 children put injured mother on door, carry her a mile for help". ''Toronto Star'', August 21, 1970. p. 8.〕 and a church roof was ripped off just minutes after parishioners had left the building after the end of the morning mass.〔"Sudbury homeless start rebuilding; loss is $17 million". ''Toronto Star'', August 21, 1970. p. 1.〕 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「Sudbury, Ontario, tornado」の詳細全文を読む スポンサード リンク
