Tornado hits Spanish fair, flood deaths reach 10

A tornado swept through a fair ground in a Spanish town, knocking down a Ferris wheel and injuring 35 people, while the death toll from flooding in the same southern region of the country rose to 10, authorities said Saturday.

The Friday tornado damaged several rides and cut electricity in the temporary fair set up in the main square of Gandia, according to its town hall website. It said 15 of the injured were seriously hurt, all of whom were treated on site.

Local media reported the fair in Valencia province was closed to the public at the time of a thunderstorm and that all the injured were fair workers.

この記事でのfairは名詞として使われています。その用法では「品評会、博覧会」といった少し堅いイメージが思い浮かびますが、fairの原義は「祝日、休暇」です。第1文のa fair groundは「市・縁日・催物などに使用する広場;博覧会場」という意味(ibid)ですので、ここのfairは地方の人が集まり商品を販売する「定期市」の事を指しているのではないでしょうか。(EnDough)
