These pieces of debris have been causing sonic booms, resulting in vibrations felt by some residents, as well as flashes of light across the sky, said the NOAA on Friday in an public information alert posted on their website.
「これらの破片は衝撃音波を生じていて、空を横切る光の点滅と同様に、一部の住人が感じた振動を引き起こした」とNOAAは金曜日に、ウェブサイト上に掲載された公開情報の警告で述べた。
