翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Bridge River Ash ： ウィキペディア英語版 Bridge River Ash The Bridge River Ash is a large geologically recent volcanic ash deposit that spans from southwestern British Columbia to central Alberta, Canada. The ash consists of dust-sized shards ellipsoidal fragments of pumice. It overlaps the Mount St. Helens Yn Ash and the Mazama Ash which were erupted from Mount St. Helens and Mount Mazama about 3,400 and 6,800 years ago. Even though the name ''Bridge River Ash'' is consistent with the Bridge River Cones, the ash did not originate from these volcanoes. The Bridge River Ash was created when Mount Meager erupted about 2,350 years ago as prevailing winds carried the ash east during eruption. This is the most recent major eruption in Canada.〔(Volcanoes of Canada: Distribution of tephra deposits in Western North America ) Retrieved on 2007-11-29〕 ==See also== *Volcanology of Canada *Volcanology of Western Canada 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「Bridge River Ash」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
